A study demonstrating the role of temperature and humidity in the spread of Corona infection



New research has shown that air temperature and humidity played a major role in determining when and where the second wave of the Coronavirus epidemic will strike, as researchers at the University of Nicosia of Cyprus confirmed that current prediction models take into account only two factors to predict places that will witness the peak of the disease spread without taking into account indicators The weather, despite assurances that with higher temperatures and low humidity, infection numbers will decrease, according to a report by the British "Daily Mail" newspaper.


The researchers explained that by including data on humidity and temperature, researchers from Cyprus were able to add a level of nuances that allow for a more accurate prediction, and the researchers wrote in their study: “The results indicate that the outbreak of the epidemic in two waves per year is inevitable because it is linked. Directly with what we call seasonality of the weather. "


The student and Demetris Drekakis from the University of Nicosia created a computer model that takes into account differences in weather as well as virus behavior, called this AIR index Airborne infection rate and focuses on the concentration of coronavirus particles under different conditions, AIR was applied to coronavirus data from the summer of 2020 in Paris and the city New York and Rio de Janeiro and managed to predict the second wave of Corona virus in these cities.


Since the coronavirus epidemic began, we have all been asked to socialize by standing or sitting six feet (or two meters) away from strangers, but a new study suggests that the distance may not be enough to prevent transmission of the virus, even in light winds. Researchers found that even in winds at 2 mph, saliva can travel 18 feet in just five seconds.


The team from the University of Nicosia in Cyprus explained that the results show that safety distance guidelines may not do all that to prevent us from contracting the Coronavirus, and the study was published in Physics of Fluid, and the team examined how the infection is transmitted through the air.


The researchers noted that in a period of epidemics where comprehensive and effective vaccination is not available, long-term planning should be by looking at the effects of weather and designing public health and safety guidelines accordingly. This can help avoid reactions in terms of strict lockdowns that negatively affect All aspects of life and the global economy.


The study, published in the Journal of Fluid Physics, found that the second wave of infection varies according to the location north or south of the equator, due to the difference in the timing of the seasons in the northern and southern hemispheres, and they confirmed that their model indicates that with higher temperatures and lower humidity , The infection numbers will decrease.
