Brazil has declared an end to its public health emergency over the Zika virus, 18 months after a surge in cases drew headlines around the world.
The mosquito-borne virus was not considered a major health threat until the 2015 outbreak revealed that Zika can lead to severe birth defects. One of those defects, microcephaly, causes babies to be born with skulls much smaller than expected.
Photos of babies with the defect spread panic around the globe as the virus was reported in dozens of countries. Many would-be travellers cancelled their trips to Zika-infected places. The concern spread even more widely when health officials said it could also be transmitted through sexual contact with an infected person.
The health scare came just as Brazil, the epicentre of the outbreak, was preparing to host the 2016 Olympics, fuelling concerns the Games could help spread the virus. One athlete, a Spanish wind surfer, said she got Zika while training in Brazil ahead of the Games.
In response to the outbreak, Brazil launched a mosquito-eradication campaign. The health ministry said those efforts have helped to dramatically reduce cases of Zika. Between January and mid-April, 95% fewer cases were recorded than during the same period last year. The incidence of microcephaly has fallen as well.
The World Health Organization (WHO) lifted its own international emergency in November, even while saying the virus remained a threat.
“The end of the emergency doesn’t mean the end of surveillance or assistance” to affected families, said Adeilson Cavalcante, the secretary for health surveillance at Brazil’s health ministry. “The health ministry and other organisations involved in this area will maintain a policy of fighting Zika, dengue and chikungunya.”
All three diseases are carried by the Aedes aegypti mosquito.
But the WHO has warned that Zika is “here to stay,” even when cases of it fall off, and that fighting the disease will be an ongoing battle.
More than half of adult women of reproductive age in Brazil have actively tried to avoid pregnancy because of the Zika virus epidemic, according to a survey carried out there.
Brazil has confirmed far more malformations of the brain in babies born to mothers who were infected with Zika than any other country.
So far, there have been 1,845 confirmed cases of what is now being called congenital Zika syndrome; a further 7,246 cases are suspected but the link to the virus has not yet been firmly established.
The survey carried out in June, led by academics in Brazil, shows that 56% of women who responded have tried to avoid becoming pregnant as a result. The numbers are no different among those who describe themselves as having religious beliefs – 58% of Catholics and 55% of Evangelicals in the survey said they were avoiding pregnancy.
In a letter to the Journal of Family Planning and Reproductive Healthcare, Dr Debora Diniz from the University of Brasilia and colleagues say there is an urgent need for Brazil to reconsider its policies on family planning and abortion, to help women who want to avoid the risk of having a baby with brain malformation.
“As indicated by the high proportion of women who avoided pregnancy because of Zika, the Brazilian government must place reproductive health concerns at the centre of its response, including reviewing its continued criminalisation of abortion,” they write.
The government should ensure better access to contraceptive methods and information, they say, arguing for a wider range of methods to be made available. Long-lasting reversible contraception such as intrauterine devices are scarce, they say, and hormonal implants are unavailable through the public services.
Women’s groups are attempting to challenge Brazil’s abortion restrictions through the courts, arguing that those infected by the Zika virus should be permitted a termination.
The team conducted a face-to-face survey of more than 2,000 women, who are literate and between the ages of 18 and 38, which corresponds to 83% of the female population.
They found that 27% had not tried to avoid pregnancy and 16% were not planning to become pregnant anyway, regardless of the Zika epidemic.
The response reflects the geographical impact of the epidemic, with a higher proportion of women from the hard-hit north-eastern region (66%) trying to avoid pregnancy than in the south (46%).
“Black (64%) and brown (56%) women were more likely to report avoiding pregnancy than white women (51%), which also likely reflects the disproportionate impact of the epidemic among the most vulnerable racial groups,” they write.
An estimated 174,000 Brazilians are said by the ministry of health to have been infected with the Zika virus, although the last updated figure was in early July.
Two weeks shy of his first birthday, doctors began feeding José Wesley Campos through a nose tube because swallowing problems had left him dangerously underweight.
Learning how to eat is the baby’s latest struggle as medical problems mount for him and many other infants born with small heads to mothers infected with the Zika virus in Brazil.
“It hurts me to see him like this. I didn’t want this for him,” said José’s mother, Solange Ferreira, breaking into tears as she cradled her son.
A year after a spike in the number of newborns with the defect known as microcephaly, doctors and researchers have seen many of the babies develop swallowing difficulties, epileptic seizures and vision and hearing problems.
While more study is needed, Zika-caused microcephaly appears to be causing more severe problems in these infants than in patients born with small heads because of the other infections known to cause microcephaly, such as German measles and herpes. The problems are so particular that doctors are now calling the condition congenital Zika syndrome.
“We are seeing a lot of seizures. And now they are having many problems eating, so a lot of these children start using feeding tubes,” said Dr Vanessa Van der Linden, a pediatric neurologist in Recife who was one of the first doctors to suspect that Zika caused microcephaly.
Zika, mainly transmitted by mosquito, was not known to cause birth defects until a large outbreak swept through north-eastern states in Latin America’s largest nation, setting off alarm worldwide. Numerous studies confirmed the link.
Seven percent of the babies with microcephaly that Van der Linden and her team have treated were also born with arm and leg deformities that had not previously been linked to other causes of microcephaly, she said.
To complicate matters, there are babies whose heads were normal at birth but stopped growing proportionally months later. Other infants infected with the virus in the womb did not have microcephaly but developed different problems, such as a patient of Van der Linden’s who started having difficulties moving his left hand.
“We may not even know about the ones with slight problems out there,” Van der Linden said. “We are writing the history of this disease.”
On a recent day, José lay on a blue mat wearing just brown moccasins and a diaper, his bony chest pressed by a respiratory therapist helping him clear congested airways.
Jose, who has been visited by the Associated Press three times in the last year, is like a newborn. He is slow to follow objects with his crossed eyes. His head is unsteady when he tries to hold it up, and he weighs less than 13 pounds, far below the 22 pounds that is average for a baby his age.
Breathing problems make his cries sound like gargling, and his legs stiffen when he is picked up. To see, he must wear tiny blue-rimmed glasses, which makes him fussy.
Arthur Conceicao, who recently turned one, has seizures every day despite taking medication for epilepsy. He also started taking high-calorie formula through a tube after he appeared to choke during meals.
“It’s every mom’s dream to see their child open his mouth and eat well,” said his mother, Rozilene Ferreira, adding that each day seemed to bring new problems.
Studies are under way to determine if the timing of the infection during pregnancy affected the severity of the abnormalities, said Ricardo Ximenes, a researcher at the Fiocruz Institute in Recife.
Also, three groups of babies whose mothers were infected with Zika are being followed for a study funded by the US National Institutes of Health. The groups include infants born with microcephaly, some born with normal-sized heads found to have brain damage or other physical problems and babies who have not had any symptoms or developmental delays.
At birth, Bernardo Oliveira’s head measured more than 13 inches, well within the average range. His mother, Barbara Ferreira, thought her child was spared from the virus that had infected her during pregnancy and stricken many newborns in maternity wards in her hometown of Caruaru, a small city 80 miles west of Recife.
But Bernardo cried non-stop. The pediatrician told Ferreira that her baby was likely colicky and would get better by the third month. Instead, the crying got worse, so Ferreira took him to a government-funded event where neurologists were seeing patients with suspected brain damage.
“At the end of the second month, beginning of the third, his head stopped growing,” Ferreira said. “Bernardo was afflicted by the Zika virus after all. I was in despair.”
In Brazil, the government has reported 2,001 cases of microcephaly or other brain malformations in the last year. So far, only 343 have been confirmed by tests to have been caused by Zika, but the health ministry argues that the rest are most likely caused by the virus.
The health minister, Ricardo Barros, said there was a drop of 85% in microcephaly cases in August and September compared to those months last year, when the first births started worrying pediatricians. He credited growing awareness of the virus and government attempts to combat mosquitoes through spraying campaigns.
Despite all the problems, some infants with the syndrome are showing signs of progress.
On a recent evening, 11-month-old Joao Miguel Silva Nunes pulled himself up in his playpen and played peek-a-boo with his mother, Rosileide da Silva.
“He is my source of pride,” Silva said. “He makes me feel that things are working out.”
On Friday the Florida State Department of Health reported four cases of Zika, and on Monday, another ten. All were likely contracted locally from mosquitoes in Wynwood, a north Miami neighborhood. The CDC is advising pregnant women not to travel to the area. Meanwhile, hundreds of women have tested positive for Zika virus in Puerto Rico. At least 2% of blood donors in Puerto Rico have recently been infected with Zika: another ominous sign the infection is spreading rapidly.
Given the geographic distribution of the Zika-transmitting Aedes aegypti mosquitoes in the US, we fully expected to see Zika cases in Florida, Texas and elsewhere along the Gulf Coast and in the Caribbean. What we didn’t expect was that Congress would be so slow to fund emergency efforts to control the spread of Zika.
Congress just went on vacation without approving emergency funds to fight the disease. They won’t reconvene until after Labor Day. In February, President Obama requested $ 1.9bn from Congress, and the Administration has continued to press Congress for funds since then. But according to US House Speaker Paul Ryan, “There is plenty of money in the pipeline right now, money that is not going to Ebola, that was already in the pipeline, that can go immediately to Zika.”
Republicans haven’t wanted to allocate new emergency funds, wanting hold to caps under the routine appropriations process.
The Ebola epidemic should have taught us the importance of strengthening disease surveillance and health systems at home and in those parts of the world where new disease threats are most likely to emerge. I suspect Republicans have been quick to push for reallocating Ebola monies to the Zika fight because they think it’s foreign aid. But, by analogy, is it foreign aid to gather intelligence or train foreign troops in the Middle East? Or are we doing that to protect ourselves?
Strategically supporting disease surveillance and health systems in Africa and elsewhere is very much about protecting our national security. But that takes time and money.

Meanwhile, the Zika funding bill currently before Congress includes provisions to cut funding for Planned Parenthood. Democrats argue that Planned Parenthood provides important obstetric and gynecological services, especially to poor women. These services include birth control, and when necessary, abortions – all services that women will need to prevent having Zika-affected microcephalic babies.
American views on abortion shifted in part due to another infectious disease: a rubella outbreak in the 1960s resulting in over 20,000 babies being born with microcephaly and other birth defects. Abortion was no longer just a sign of moral failure. It became a white, middle class issue, in much the same way that opioid abuse has today. But regardless of where you stand on abortion or Planned Parenthood, I’d argue that we need new funding to fight Zika.
Our system for financing public health emergencies is broken. If we were under attack by Russia or North Korea, you can bet that Congress would immediately approve emergency funding to fight back and defend our shores. We have federal disaster relief funds on hand should an earthquake or hurricane or flood hit. But when a public health threat strikes, we’re caught off guard with our pants down.
We can’t keep playing this shell game: defunding long-term, strategically important public health programs to respond to emergencies. Siphoning off funds from other public health programs – such as the national strategic stockpile of vaccines and other emergency supplies to combat epidemics – to fight Zika doesn’t make sense either. Moreover, local public health departments – our frontline defense against disease outbreaks –have suffered huge funding cuts and lost one-fifth their manpower since the 2008 recession.
We know that the combined forces of globalization, climate change, population growth, urbanization and poverty will lead to more frequent disease outbreaks. It’s our “new normal.” And we can be certain that members of Congress will try to leverage any crisis to their party’s advantage. But politics must not get in the way of our ability to protect the American people. We must insist on stable, permanent funding for public health emergencies because we know there are many more to come.
It’s time to acknowledge that sometimes being a world leader means doing what’s best for our people – even when that means doing good for the rest of the world too.

Sao Paulo is fighting a significant outbreak of dengue fever. The disease spreads swiftly in crowded locations. Photograph: Mauricio Lima/AFP/Getty Images
Brazil has the highest incidence of dengue fever in the globe.
Final year, instances spiralled to a new substantial of 1.4 million and the trend demonstrates no indications of abating. São Paulo, host city for the opening ceremony of the FIFA World Cup on June twelve, battled a significant dengue outbreak this month. “Our campaign has not been effective,” laments Guilherme Ribeiro, an epidemiologist who specialises in infectious ailments at the Institute of Collective Health at the Federal University of Bahia. “We commit a great deal of funds and dengue is a priority for the government but regrettably 2013 was the worst 12 months on record.”
Ribeiro understands the mosquito-borne illness effectively having suffered the fever twice and studied it up shut in his native Salvador. A sprawling metropolis of two.6 million with large rises towering more than a sea of shanty towns, Brazil’s third largest city is a prime breeding ground for the Aedes aegypti mosquito which transmits dengue. Salvador is a single of the twelve host cities for the Planet Cup and wellness officials are paying near consideration. In mid-June, the rainy season will commence tapering off and dengue will be at its peak in the area.
Not like malaria and yellow fever which are primarily found in the Amazon states and other thinly populated components of the nation, dengue is rampant in urban places in which 85% of Brazil’s population lives. Swiftly increasing cities and towns have supplied an best environment for the spread of dengue. A tropical climate combined with bad infrastructure for water and sanitation motivate the proliferation of the Aedes mosquito, which can breed in as little as a teaspoon of water.
But what can make the urban mosquito specially hazardous is the truth that in densely populated neighbourhoods, it does not have to travel far to infect a massive number of individuals. A latest examine warned that, “overcrowded cities current extremely favourable situations for enhanced transmission,” and that São Paulo was in danger of turning out to be a sizzling spot due to the fact all four dengue virus strains have been in circulation there throughout an outbreak in 2013 – a first for a massive city in Brazil.
There is no cure for dengue and it can sometimes be fatal. Public health professionals are pinning their hopes on a vaccine which they feel will be the most powerful way to fight the ailment. A number of vaccines are in growth and Brazilian scientists are doing work on one edition at the Butantan Institute in São Paulo. It was produced in partnership with the US-primarily based Nationwide Institutes of Health. Early outcomes are promising and the vaccine will be moving into phase 3 clinical trials at the finish of up coming year.
In the meantime, the best way to get rid of mosquitoes is to eliminate their breeding locations but Salvador is a excellent example of how chaotic urban sprawl can make the process almost not possible. “The mosquito is incredibly effectively adapted to our urban setting,” says Ribeiro pointing to the blue water tanks which are a common sight on rooftops close to the city. They also come about to be an ideal incubator for mosquito larvae which thrive in dark, damp spaces. The tanks are extensively utilised because piped water provide during the city is intermittent. There is widespread public awareness about the want to keep tanks and water containers covered and clean but it does not always translate into action. “The campaign only functions when the local community participates,” says Angélica Andrade Santos, a well being official in the Pau da Lima area.
A single of the favelas (shanty towns) in Pau da Lima is a base for epidemiologists like Ribeiro who go there to perform discipline research on infectious ailments. There are presently a few dengue instances in late March, such as one particular 16-year previous with hemorrhagic fever, the most virulent sort. In accordance to a nevertheless-to-be published research carried out in 2010 by the Institute of Collective Wellness and the Oswaldo Cruz Basis, 95% of the adults in this favela have been exposed to the virus. But dengue is not confined to poor neighbourhoods. Other research have located that the virus circulated in densely populated neighbourhoods across the city affecting rich and bad alike.
Dengue Mata (Dengue Kills) billboards greet visitors as they drive into the city from the airport. It is a blunt warning from the well being department to the several site visitors and soccer supporters who will quickly be arriving in Salvador. Simon Hay, an Oxford-based epidemiologist, urged Brazilian authorities to aggressively remove mosquitoes all around the northeastern stadiums.
But Ribeiro says it is unlikely that the ultra-modern Arena Fonte Nova poses a dengue threat simply because it is a nicely maintained public space with extremely tiny standing water. He advises site visitors to instead be alert to the risk on the streets saying, “one week in Salvador is a lot more risky than currently being at the stadium.”

Scientists operating with Prof Hay have recognized nine of Brazil’s stadiums as getting in dengue-plagued regions.
“Dengue fever could be a substantial dilemma in some of the tournament areas, and preventive measures are required,” Prof Hay writes in the journal Nature.
“Fifa, the Brazilian authorities and the World Cup sponsors must use their influence and experience to communicate the risk.”
The season for dengue fever normally ends in Might, a month just before the Globe Cup is due to get started.
But the northeast of Brazil is going through a heatwave, and public wellness officials warn that the mosquito breeding season might extend by means of the Planet Cup.
The north-eastern cities of Natal, Fortaleza, Recife and Salvador will host 21 video games amongst them, which includes Germany vs Portugal, Spain vs the Netherlands and potentially, a number of England video games.
England’s very first game towards Italy will be held in the humid setting of Manaus, in the Amazon rainforest.
If England finish prime of their group, they will play the runners-up from Group C in Recife’s Arena Pernambuco on June 29.
Should they win that game, their quarter-last will be held in Salvador’s Arena Fonte Nova six days later.
If they finish second, their quarter-final will be held in the Estadio Castelao in Fortaleza.
Climate researchers from the University of Reading say there is a 60 per cent likelihood of an El Nino event for the duration of the World Cup, which could lead to heatwaves and drought in Brazil.
El Nino is characterised by larger sea temperatures in the Pacific Ocean.
It typically brings about large amounts of rain, major to floods on the west coast of North America.
But in South America, it can lead to drier and hotter weather and create the ideal breeding circumstances for mosquitoes.
Dengue fever is a viral infection that generally produces a extreme fever and large temperature, among other symptoms that may possibly call for hospitalisation.
The condition has a basic stage and a significant stage that influences around 5 per cent of sufferers.
It can lead to seizures and excruciating joint discomfort, explaining why dengue is also identified as “break bone fever”.
The virus has 5 separate subtypes, with subsequent infection by one more type far more most likely to lead to severe signs and symptoms, this kind of as the life-threatening dengue haemorrhagic fever.
It is transmitted by female Aedes aegypti mosquitoes, which bite in the course of the day and lay their eggs on stagnant water.
There is no remedy or vaccine, so public health bodies in Brazil have attempted to lessen the risk of Dengue fever using insecticides and larvicides, and by targeting the areas of water on which mosquitoes breed.
But there may possibly be a novel solution on hand in time for the Planet Cup.
British biotec company Oxitec has created a mosquito with a modified gene that can only be kept alive with the antibiotic tetracycline. The modified males are launched to mate with the wild female population. Their offspring is unable to survive without antibiotics.
Brazil has, for the past two many years, conducted a trial of the genetically modified mosquitoes in Bahia state.
Brazilian company Moscamed released the world’s greatest ever swarm of GM mosquitoes in Jacobina, a town in Bahia, final month.
“We need to have to supply alternatives since the technique we have now in Brazil doesn’t work,” stated Aldo Malavasi, the president of Moscamed.
“We have thousands and thousands of cases of dengue and that expenses a whole lot for the country. Folks are unable to function.”
The company has reported a 90 per cent drop in wild Aedes aegypti mosquitoes in the town so far.
Earlier this month, Jenny McCarthy, the anti-vaccine movement’s loudest proponent, disavowed her earlier arguments. As an alternative, she claimed that she by no means advised anybody not to vaccinate their kids and that she simply opposes doctors providing children several immunization shots at as soon as.
That McCarthy at some point took a single modest phase toward the nearly universally agreed upon truth that vaccines conserve lives and never trigger autism is excellent information, but it may be as well minor also late: the anti-vaccination motion in the United States has helped to usher in outbreaks of preventable conditions in states coast to coast.
In New York and California, measles outbreaks are bigger than they’ve been in decades. A lower of vaccinations across Europe brought with it 26,000 situations of measles in 2011. And one Australian survey discovered that 83% of Sydney homeopaths suggested their customers against vaccinating.
Opting out of vaccines or insisting on a schedule for administering them, as McCarthy now suggests, that puts other individuals at chance (simply because your own kid could be protected by herd immunity) is unconscionably selfish. That the very good that comes from vaccinating youngsters towards deadly diseases can be characterized as a “gray zone” – allow alone topic to national debate – is the height of Initial Globe Problems.
And yes, as McCarthy asserted, each youngster is distinct – but the actually “diverse” kids we must be anxious about are the 22m youngsters who overwhelmingly reside in building countries like India, Indonesia and Nigeria, who are denied even basic entry to immunizations, let alone the proper to choose their own distinctive vaccine routine.
As significantly as McCarthy and other folks might want to think that immunizations are an problem of personalized option, decisions not to vaccinate influence young children outside of your very own home and, more and more, across borders and oceans.
I go through McCarthy’s Chicago Sun-Times editorial just a number of days after going to a tiny local community healthcare clinic outside of Sao Paulo, the place immunizations are part of the regimen care its sufferers get. Brazil’s immunization program is 1 of the most amazing in the planet. The government tends to make most of its personal vaccines in the country and distributes them cheaply and universally, which led to a steep decline in infant mortality and deaths from infectious ailments right after the national vaccination program started in the 1970s – one particular chart illustrating polio infection rates exhibits a total drop-off a couple of years right after nationwide immunization campaigns. Now, although, Brazil is seeing tiny outbreaks of illnesses like measles. But they are not homegrown – they’re reportedly coming in from Europe and the United States, thanks to anti-vaxxers.
In a lot of techniques, Brazil is a model for how national vaccination packages can function, and how vaccines can accelerate a country’s advancement, health and development. The country’s implementation of widespread cost-effective vaccinations, coupled with an expanding public health program, induced infant mortality to plummet and contributed to a greater regular of residing, a more healthy populace and a more robust economic climate. But right now, Brazilian pubic overall health officials are newly concerned that some of the richest, most produced nations on the planet threaten their achievement
In accordance to Dr Homma, the Globe Cup is specifically troubling – the influx of vacationers, he mentioned, might bring with it unvaccinated Americans and Europeans, putting Brazilians at threat. Brazil has not experienced a measles outbreak in more than a decade and the Americas take into account the condition eradicated – but with half a million new site visitors coming into Brazil for the June sporting occasions, the Pan American Well being Organization and the WHO accredited an emergency program to fight likely outbreaks.
The most scary affect of vaccine denialism is the straightforward fact that when we are capable to cross borders with ease and accessibility data from all around the globe, it’s significantly easer to spread both deadly diseases and bad suggestions.
The anti-vaccine contingent – whose most recent celebrity proponent is Alicia Silverstone – that argues vaccines can negatively have an effect on kids, and in some instances, even go so far as to say vaccines cause autism, largely has the privilege of living in locations in which numerous deadly communicable illnesses are uncommon. This means that even the unvaccinated children of anti-vaxxers have a rather very good chance of in no way contracting the illnesses for which they eschew the shots – simply because of the herd immunity brought on by the identical vaccines these grownups oppose. Which is a luxury not afforded to mother and father and youngsters in much of the globe.
In accordance to the WHO, vaccination prevents among two and 3 million deaths every yr. Vaccines shield individuals who are immunized, but also infants also little for vaccinations, immune-compromised people such as people undergoing specific cancer remedies, and individuals who are resistant to immunizations. You can also aid the 22 million kids who lack accessibility to vaccinations around the world get the standard shots they require by providing to the Gavi Alliance.
Plus, up coming week is Planet Immunization Week – so there is no much better time to stick it to the Jenny McCarthys of the globe by generating positive that your own stickings (and your kids’) are up to date.
To mark planet leprosy day on Sunday, campaigners and sufferers go over how Brazil’s network of colonies have excluded individuals with the condition and hampered efforts to raise awareness. The government has been urged to allocate far more funding to support eradicate the problem and increase the lives of individuals affected by it
