A study from the University of Maryland has shown that the virus has spread most in cities and regions of the world where average temperatures have been around
5-11C (41-52F) and relative humidity has been low.
But there have been considerable numbers of cases in tropical regions, too. A recent analysis of the spread of the virus in Asia by researchers at Harvard Medical School suggests that this pandemic coronavirus will be less sensitive to the weather than many hope.
They conclude that the rapid growth of cases in cold and dry provinces of China, such as Jilin and Heilongjiang, alongside the rate of transmission in tropical locations, such as Guangxi and Singapore, suggest increases in temperature and humidity in the spring and summer
will not lead to a decline in cases. They say it underlines the need for extensive public health interventions to control the disease.
