Many new data help reinforce the view that SARS-CoV-2 spreads more slowly in hot countries.
According to the New York Times, recent studies show that SARS-CoV-2 virus spreads rapidly at temperatures of 3-17 degrees Celsius. Therefore, warm climates are less likely to contract Covid-19.
Also according to this study, countries near the equator and in the Southern Hemisphere are reported to have 6% fewer cases globally.
“Wherever the temperature is cold, the number of infections increases faster. In Europe, although the health system is considered to be the leading, there is a spike in cases, “said Qasim Bukhari, a researcher from Massachusetts Institute of Science and Technology.
Dr. Deborah Birx, global AIDS coordinator in the United States, said the pandemic was similar to SARS in 2003. But because it broke out in China and South Korea, the identification of symptoms was similar to SARS. should be difficult.
An analysis of researchers in Spain and Finland also said that the virus lives in regions with low, dry temperatures.
The temperature factor that affects the spread is also easily visible in the US. Warm temperatures, such as Arizona, Florida and Texas, have slower outbreaks than cold states like Washington, New York and Colorado. States like California have moderate outbreaks due to temperatures that are not too cold or hot.
The Chinese government also published a report with such content. During the outbreak period, the incidence of infection in subtropical cities was lower than in cold regions
“We need stricter precautions, hot temperatures can reduce the possibility of spread but does not mean there will be no infection,” Mr. Bukhari added. Although difficult to grow in hot climates, the virus can survive for several hours on surfaces and air.
Jarbas Barbosa, assistant director of the WHO regional office for the WHO, will take 4-6 weeks to be able to more clearly determine how Covid-19 develops in different weather. . At the same time, there are many mysteries about Covid-19 yet to be discovered, so it is unclear whether the next fall, SARS-CoV-2 will thrive.
