(PTI) Scientists have confirmed for the first time that the COVID-19 can not be transmitted by mosquitoes, a finding that proves World Health Organisation's claim that the disease is not mosquito borne.
The research published in the journal Scientific Reports, provided the first experimental evidence on the capacity of Coronavirus, to infect and transmitted by mosquitoes.
Here we provide the first experimental data to investigate the capacity of Coronavirus to infect and transmitted by mosquitoes, the study noted.
While the WHO has already stated that mosquitoes can not transmit the virus, our study is the first to provide conclusive data supporting the theory, said Stephen Higgs, co-author of the study from Kansas State University in the United States.
According to the study, conducted at the University's Biosecurity Research Institute the virus is unable to replicate in three common and widely distributed species of mosquitoes --Aedes aegypti, Aedes albopictus and Culex quinquefasciatus, and hence can not be transmitted to humans.
Samples collected by the scientists within two hours of inoculation in mosquitoes confirmed eficient delivery of infectious viruses to these insects. However, based on the lack of detectable infectious virus in any of the 277 samples collected at all time points beyond 24 hours post-inoculation, the scientists said Coronavirus can not replicate in mosquitoes.
Even if a mosquito fed on a person with virus in the blood, the mosquito would not be a vector is feeding on a naive host, researchers concluded.
We observe that even under critical situation, Virus is unable to replicate in these mosquitoes and therefore can not be transmitted to people even in the unlikely event that a mosquito fed upona viremic host, the scientists mentioned in the study.
