Will warmer weather push down the number of confirmed Novel Coronavirus or COVID-19 cases?
International experts say it is still too early to tell.
Harvard Health Publishing writes in a report published on March 13, 2020: "Some viruses, like the common cold and flu, spread more when the weather is colder.
"But it is still possible to become sick with these viruses during warmer months.
"At this time, we do not know whether the spread of COVID-19 will decrease when the weather warms up."
Looking into the behavior of the common cold and flu, National Geographic reports that "flu season" has long been associated to the winter months of the northern hemisphere.
For tropical countries, "flu season" is more common during rainy seasons.
Why is that so?
Research suggests the reason stems from two major factors: people in closed quarters and the dry, cold air.
National Geographic states, "Some suggest it's closer quarters—to escape the cold weather, people cluster indoors, where human-to-human transmission becomes more likely…
"And relatively recent research suggests that dry, cold air may also help viruses stay intact in the air or travel farther as they become airborne...
"Warmer air holds more moisture, which prevents airborne viruses from traveling as far as they would in dry air."
But experts and scientists underline that there is still so much about COVID-19 that is uncertain, according to CNN.
While there is evidence that COVID-19 appears to thrive in colder weather—as seen in the world's worst-hit countries: China, Italy, and South Korea— the fact that there are also large cases of COVID-19 in warmer places challenge that.
And with research about the coronavirus still at its preliminary stages, experts cannot give a conclusive answer yet.
But in case the virus does slow down in the summer season, U.S. military medical researcher Nelson Michael suggests government should take advantage of that time and use it to reassess the country's health care system and "buy time for a potential vaccine to be developed."
Brittany Kmush, a public health expert at New York's Syracuse University, reiterates in the same CNN report: "There really still is so much unknown about this virus.
"If case numbers decrease over the summer, it is a good idea to prepare for a resurgence during the colder months."
