A new study has informed us that the warm and humid temperature lessens the chance of multiplication of coronavirus. Many of the largest outbreaks have been in regions where the weather is cooler. This leads to the prediction that the disease might begin to fall off with the arrival of summer.
The researchers analyzed how the epidemic evolved in various Chinese cities taking into account the weather in each. They also compared how the virus multiplied in countries with relatively lower seasonal air temperature and lower humidity. Some of these countries with low seasonal temperatures are Korea, Japan, and Iran.
Recent paper from MIT researchers further suggest that higher temp and humidity seem to slow virus spread and it may have seasonality: https://t.co/6rL93HP6Oj

These countries experience more severe outbreaks compared to its spread in warmer and more humid countries. Some of the warmer countries are Singapore, Malaysia, and Thailand, where the Coronavirus outbreaks have been more limited.
Is the Outbreak of Disease is Based on the Season?
Some of the diseases like Flu typically arrives with the colder winter months. Typhoid tends to peak during the summer. Measles cases drop during the summer in temperate climates, while in tropical regions they peak in the dry season.
From this, we can understand that each and every disease has its outbreak at a particular season. This thing applies to corona too.
The virus that causes COVID-19 which has been officially named SARS COV-2 is too new to have any firm data on how cases will change with the seasons.
A study conducted 10 years ago by Kate Templeton, from the Centre for Infectious Diseases at the University of Edinburgh, UK. He found that three coronaviruses, all obtained from patients with respiratory tract infections at hospitals and GP surgeries in Edinburgh showed “marked winter seasonality”. These viruses seemed to cause infections mainly between December and April a similar pattern to that seen with influenza.
Can Warm and Humid Weather Distance us from the Coronavirus?
There are some early hints that COVID-19 may also vary with the seasons. The spread of outbreaks of the new disease around the world seems to suggest it has a preference for cool and dry conditions.
So in cold dry weather, the basic reproduction number of the new coronavirus is somewhere between 2 and 3. This shows that each infected person passes along the virus to an average of 2 to 3 other people.
So it is clear that the warm climate helps to lessen the multiplying rate of corona but still, it is advised to stay in our home rather be out in the sun. Because even the multiplying rate is less, the spreading of corona remains the same.
