The increase in the rate of spread of Covid-19 is linked to temperature and humidity, which in its case increases in different regions in different months of the year.
This was revealed in a medical study conducted in the United States.
Research from the University of Florida found that in colder climates, the northeastern states of the United States may experience more cases during the winter, while in warmer regions, such as the southern states, it may occur in the summer.
Similarly, temperate regions can be exposed to 2 waves of code.
Experts involved in the research said that we believe that cod can become endemic, meaning that it will remain in human populations, but the geography of a place will play a role in its wave. How low or high the temperature.
The study found that specific increases or decreases in temperature and humidity led to an increase in the number of Covid-19 cases in the world’s worst-affected areas.
For example, cases increased when the temperature dropped below 17C or rose above 24 C.
Similarly, the virus survives longer in humid areas in dry environments.
“We need to tailor epidemic prevention strategies to the environment in our residential areas,” the researchers said.
He said that Florida, Africa and India are tropical regions but there faced Covid-19 waves, but the time of increase in cases there was different from the waves of more cold regions.
However, he added that the number of cases may increase during severe cold or heat waves, but only when the temperature is maintained for an average of 14 days.
He said that the temperature and humidity of an area play an important role in the volume of viral particles, as it determines the vitality of the particles in the atmosphere.
The dry weather in cold regions evaporates water from viral particles and shrinks their volume, allowing them to swim longer in the air.
He explained that in colder climates, people prefer to stay indoors and there is a higher risk of spreading viral particles.
In contrast, warmer areas with higher humidity have higher amounts of water in their air, which causes viral particles to grow larger and roar faster on the floor.
But at the same time, people spend more time indoors to escape the heat outside, and the risk of cod increases when the air drainage system is faulty.
Human behavior is a key factor in the spread of the virus, researchers say.
The study found that temperatures between 16 and 23 degrees Celsius show a lower number of cases, which is the temperature that people consider to be tolerable and spend time outside.
The researchers said that the research confirms previous findings related to the low temperature and humidity code, which also shows how the virus spreads even in hot weather.
He said the results showed once again how complex the weather and Corona’s relationship is.
Researchers emphasize the use of masks such as proper ventilation and filtration, which are important steps to prevent the spread of the disease.
He said that better air ventilation and face masks could reduce the rate of cod cases, even in large and somewhat crowded places.
The findings were published in the American Journal of Tropical Medicine and Hygiene.
