Will Houston’s hot and humid weather protect against the spread of coronavirus?

Spring is coming, will that help?

HOUSTON – I received my first Bluebonnet Click2Pin yesterday! A sure sign that Spring is around the corner! A sign of even warmer weather although we stay fairly dry with the humidity not becoming too strongly felt until late May.

Will either the heat or humidity help with the Covid-19, popularly known as Coronavirus? Well, understand that the common cold and the flu are also in the category of “coronavirus” and so it’s natural to look at how colds and the flu are transmitted from person to person. We usually see more cold/flu increase in the winter because people gather together more often indoors as opposed to warmer months. So just getting away from each other might be part of the solution in terms of transmission.

These cold and flu viruses are person-to-person airborne transmissions so the air itself will make a difference. Dry air tends to support viruses floating around while humid air, with more water droplets, has those airborne viruses falling to the ground. Thus, humid air may help slow infection rates. Fewer virus molecules in the air the better. Check that “good” box for Houston.

In addition, studies do indicate that such viruses do not live as well in hot weather as cold (consider that this whole thing started in the winter months in China). Of course, just how hot can matter and we’re not going to get extremely hot until summer. We are, however, expecting a warmer than normal March to May across much of the country:

Warmer spring than normal

Let’s hope the heat helps.

Covid-19′s big concern is that it transmits quickly and easily from person to person. And while Spring may be a more hostile host for this virus, those months are big travel times whether it’s school breaks, conferences, or seeking a break from winter’s cold weather. THAT will bring more people together which will cause more infections. We may not be as close to each other as in winter, but there will be more of us from different parts of the country and world congregating.

Let’s hope for a quick vaccine. Bluebonnets die at the end of Spring. Covid-19 is not likely to just wither the same way.
