Where is the risk of the next pandemic?Who: Probably mosquitoes


Insect-borne pathogens pose an “increasing” risk and could cause the next pandemic, according to the World Health Organisation (WHO), the Daily Mail reported.Who says pathogens like Zika, yellow fever, chikungunya and dengue are spread by arthropods such as mosquitoes and ticks.They are the top killer of the next potential outbreak that could escalate into a pandemic, especially since nearly 4 billion people live in tropical and subtropical regions where these animals thrive.Experts around the world are looking for strategies to prevent outbreaks like COVID-19 from happening again, the report said.”We have been through two years of COVID-19, and we have learned the lessons of failing to adequately prepare for high-impact events,” Dr. Sylvie Briand, director of the WHO’s Global Infectious Disease Preparedness Team, said at a briefing on March 31.”We got signals in previous SARS and flu pandemics, but we still have gaps in preparedness,” Briand said.The next pandemic is likely to be caused by a new arbovirus.We are also seeing some signals that these risks are increasing.”Briand was speaking at the launch of WHO’s new Global Arbovirus Initiative, which aims to work together to address arbovirus threats.The prevalence of arboviruses is increasing and now poses a threat to public health in tropical and subtropical regions, Briand said.More than 89 countries have faced Zika outbreaks since 2016, while yellow fever risk has been rising since the early 2000s.In 130 countries where dengue is endemic, 390 million people are infected each year, and severe cases can lead to haemorrhagic fever and death.Yellow fever is at high risk of outbreaks in 40 countries and can cause jaundice, severe haemorrhagic fever and death.Chikungunya is less well known, but it is present in 115 countries and can cause severe and disabling arthritis.Who believes that while there is a yellow fever vaccine, for other diseases, the best protection is to prevent mosquito bites in the first place.The global Arbovirus Initiative will focus resources on risk surveillance, pandemic prevention, preparedness, detection and response, who said.Given the frequency and scale of arbovirus outbreaks, especially those transmitted by Aedes mosquitoes, international action is critical, the organization said.(Edit: DXY)
