While the possibility for reduced spread of SARS-CoV-2 due to hot weather cannot be ruled out, it will be unwarranted to assume that Covid-19 will vanish down the summer, according to an Indian virologist.
The arrival of summer in India may have raised hopes that hot and humid weather could slow the Covid-19 progression but virologist Naga Suresh Veerapu believes that outbreak and pandemic occurrences often do not follow seasonality.
Veerapu, Assistant Professor, Department of Life Sciences, Shiv Nadar University, Uttar Pradesh noted that it is too early to speculate on the changes in the epidemiological landscape of SARS CoV-2 with the seasons.
"It is sensible to rationalise that high temperature reduces the spread of SARS-CoV-2, unwarranted though assuming the virus vanishes down the summer," he told PTI.
In April, researchers at the Massachusetts Institute of Technology in the U.S. announced that a warm and humid weather is linked to slower spread of the novel coronavirus, suggesting that Asian countries experiencing monsoon may experience lesser transmission of the virus.
However, a global study published last week in the Canadian Medical Association Journal, found that temperature and latitude are not associated with the spread of Covid-19 disease, adding that school closures and other public health measures were, on the other hand, having a positive effect on containing the novel coronavirus.
Veerapu noted that the possibility for reduced spread of SARS-CoV-2 due to hot weather cannot be ruled out, and India can gain the window of opportunity to work on countermeasures to contain the disease.
However, he explained that regardless of the hot weather, SARS-CoV-2 may continue human-to-human spread under household conditions, and in confined spaces.
