New research shows that the Coronavirus pandemic can become a seasonal disease. This is reminiscent of the influenza virus in winter. The SARS-CoV-2 virus infection shows a decrease in infection as the summer season starts. Some researchers also claim that a rise in temperature helps decrease the virality of COVID-19. This means that the virus will spread more freely with a dip in temperature and humidity. This makes winter season the playground for Coronavirus.
According to the studies present in Transboundary and Emerging Diseases, COVID-19 will become an annual seasonal disease. This means that there needs to be proper regulation by the time winter arrives or else we might look at a massacre. This is exactly why the infection started in winter in China. The temperature apparently also helps spread the fomites (viral air particles) in the low humid air.
COVID-19: A seasonal disease in Winter
According to these researchers, the arrival of winter will also mean the arrival of coronavirus. Professor Michael Ward, an epidemiologist in Sydney School of Veterinary Science at the University of Sydney, says the pandemic spread all across China, America, Europe, and other countries in the month of winter in 2019. This means every country will be affected by the virus in a surrounding of cool temperature.
Vaughan Gething says if restrictions are lifted too quickly, there is a ''very real risk'' there could be a second peak of coronavirus, particularly in the winter when the NHS is at its busiest https://t.co/zPQcwnrtq2 pic.twitter.com/ZpjAaM8DHz

Previous studies noted that relative humidity and temperature play a major role in the spread of the SARS related disease. However, recent studies confirm that the virus is directly related to humidity and not temperature. This means a sudden drop in temperature may not be enough to trigger the virus infection. However, a drop in humidity will affect the way the virus spreads even if it is not winter.
