Coronavirus is just not transmitted by mosquitoes, research reveals


Washington, July 19

Scientists have confirmed for the primary time that the novel coronavirus behind the COVID-19 pandemic can’t be transmitted to individuals by mosquitoes, a discovering that provides proof to WHO’s declare that the illness is just not mosquito-borne. 

The analysis, printed within the journal Scientific Reports, supplied the primary experimental proof on the capability of SARS-CoV-2, the virus that causes COVID-19 illness, to contaminate and be transmitted by mosquitoes.

“Here we provide the first experimental data to investigate the capacity of SARS-CoV-2 to infect and be transmitted by mosquitoes,” the research famous.

“While the World Health Organization (WHO) has definitively stated that mosquitoes cannot transmit the virus, our study is the first to provide conclusive data supporting the theory,” mentioned Stephen Higgs, a co-author of the analysis from Kansas State University within the US.

According to the research, performed on the college’s Biosecurity Research Institute, the virus is unable to copy in three widespread and extensively distributed species of mosquitoes—Aedes aegypti, Aedes albopictus and Culex quinquefasciatus, and therefore can’t be transmitted to people.

Samples collected by the scientists inside two hours of inoculation in mosquitoes confirmed environment friendly supply of infectious viruses to those bugs. 

However, based mostly on the dearth of detectable infectious virus in any of the 277 samples collected in any respect time factors past 24 hours post-inoculation, the scientists mentioned SARS-CoV-2 can’t replicate in mosquitoes. 

“Even if a mosquito fed on a person with virus in the blood, the mosquito would not be a vector if feeding on a naive host,” they concluded.

“We demonstrate that even under extreme conditions, SARS-CoV-2 virus is unable to replicate in these mosquitoes and therefore cannot be transmitted to people even in the unlikely event that a mosquito fed upon a viremic host,” the scientists wrote within the research. PTI
