Mosquitos to be infected with bacteria in fight against Zika virus

Mosquitoes in two large areas of Brazil and Colombia are to be infected with bacteria that deprive them of the ability to transmit viruses, in an attempt to check the spread of Zika, which has been held responsible for brain damage in thousands of babies.


Funding the ambitious plan are two philanthropic foundations – the Wellcome Trust and the Bill and Melinda Gates Foundation – together with the Brazilian, UK and US governments. The scheme will cost $ 18m (£14.7m) and is supported by the World Health Organisation (WHO).


Wolbachia bacteria are carried by around 60% of the world’s insect species, but not by the Aedes aegypti mosquito, which transmits Zika, dengue, yellow fever and chikungunya viruses to humans.


Researchers at Australia’s Monash University have been working for the past decade to infect mosquitoes with Wolbachia in an effort specifically to eliminate dengue, but the Zika crisis in Latin America has focused attention and now major funding on their work.


Following successful trials in Australia, Indonesia and Vietnam, including small-scale projects last year in Latin America, Wolbachia-infected mosquitoes will be released across two large urban areas – in Rio de Janeiro in Brazil and in Antioquia in Colombia, starting next year. The infected mosquitoes breed with local mosquitoes and pass the Wolbachia bacteria on to their offspring, so the project is self-sustaining. In those areas where trials have been done so far, transmission of the viruses has stopped.


“Wolbachia could be a revolutionary form of protection against mosquito-borne disease. It’s affordable, sustainable, and appears to provide protection against Zika, dengue, and a host of other viruses. We’re eager to study its impact and how it can help countries,” said Dr Trevor Mundel, president of the global health division of the Bill and Melinda Gates Foundation.


The World Health Organisation earlier this year called for large-scale pilot studies of the Wolbachia mosquito-control method and the Pan-American Health Organisation offered technical support in countries affected by Zika.


The idea emerged from the Grand Challenges programme backed by the Gates Foundation, which each year calls for scientists to bid for funds with creative new ideas to solve some of the world’s most pressing health problems. Prof Scott O’Neill’s team from Monash University proposed Wolbachia infection of mosquitoes to stop dengue transmission in 2005.


Jeremy Farrar, director of the Wellcome Trust, told the Guardian it was vital for the scientists to ensure they had local support for what will still be a trial. “Community involvement is absolutely fundamental,” he said. A huge amount of work, over years, had gone on to explain the project to people living in areas where earlier trials had taken place. “Get that sort of community intervention wrong and you never recover from that,” he said.


There are great hopes for Wolbachia but it is too soon to suppose this is the answer to the Zika and dengue epidemics. Farrar said he would wait to see whether it worked. “I’m in equipoise. I really hope it will, but I’d like to see the evidence at scale.”


Sue Desmond-Hellman, chief executive of the Bill and Melinda Gates Foundation, in London with Farrar for the latest Grand Challenges meeting where new projects are presented and funding awarded, said she agreed.


“What I feel most confident about is that it is safe,” she said. “We know that Wolbachia is already found in 60% of the world’s insects. Everyone in this room has probably been bitten by something with Wolbachia.”


Aedes aegyti mosquitoes are found across large areas of the world, including the southern part of the United States, parts of Asia and Africa. Methods to control the populations or limit the damage they can do in transmitting viral infections are urgently needed. The director of the US Centers for Disease Control and Prevention said on Tuesday that there was not yet a way to contain the spread of infections.


“Zika and other diseases spread by [the Aedes aegypti mosquito] are really not controllable with current technologies,” said Thomas Frieden. “We will see this become endemic in the hemisphere.”


More than 50 countries have experienced an outbreak of Zika virus infections since 2015, according to WHO data, and there have been nearly 2,200 cases of microcephaly – babies with brain damage – associated with Zika, 28 of which have been reported in the US. The vast majority – 2,033 – were reported in Brazil.

Queensland doctors warn 46 infants infected in outbreak of incurable virus

Dozens of Australian babies are contaminated by a virus that has no remedy, doctors say.


Associate Professor Theo Sloots says 46 infants are infected with parechovirus, which has spread to Queensland. At least 11 instances have been confirmed in the state because December.


“The outbreak is Australia-wide now and we believe there are at least 4 kinds of the virus,” the Queensland Paediatric Infectious Conditions (QPID) laboratory director informed reporters in Brisbane.


“We don’t know what type is in Queensland in contrast to other states.”


Parechovirus is a respiratory and intestinal condition that triggers fever, irritability, rash and diarrhoea, but significant instances can develop into hepatitis or encephalitis.


QPID Associate Professor Michael Nissen said the virus contaminated mostly infants, but no 1 was sure in which it came from, how frequently it occurred or how to battle it.


“This virus does not respond to typical antibiotics,” he stated.


But Nissen said humans need to have been ready to fight it because it has been about for a long time – medical professionals just were not in a position to detect it.


The QPID laboratory has lately created a test to recognize the virus in patients inside of a day.


“It is crucial to diagnose the infection early and distinguish it from other achievable leads to,” Nissen said.


The next normal phase would be creating a vaccine, but he said until then the ideal way for mothers and fathers to avoid parechovirus was excellent hygiene all around babies.


This incorporated washing hands after going to the toilet, prior to eating, right after wiping noses and after modifying nappies.


“It truly is actually widespread-sense things,” Nissen said.
