The temperature is going up, and there have been discussions that heat and humidity may limit the spread of COVID-19. According to WebMD, there isn’t enough evidence to know if it's true or not.
Not enough evidence
Scientists have been trying to re-create the real-world conditions in lab, but they are various and difficult to be duplicated. Also, virus may change depending on the environment. There have been studies showing that the coronavirus in Asian areas and the US are not 100% the same.
Even based on real-world examples, researchers found the evidence unclear. Though some viral illnesses seem to slow in the summer months, this isn’t always the case. For example, COVID-19 has spread very quickly in Australia despite the warm and humid environment.
Therefore, there’s no reason for you to assume that summer months will be safer for the transfer of COVID-19, and you still need to protect yourself and those around you.
Is “6 feet” really safe?
We are told to stay 6 feet away from others in order not to be infected. But is the distance that reassuring? To answer this question, you first need to know how long the virus can live in air and on surfaces.
Spread through air
In most situations, the droplets produced when an infected person sneezes or coughs won’t travel longer than 6 feet, that’s why 6 feet is a “safe distance.” However, many other factors should be taken into consideration during this process, including people’s vulnerability, and whether they are outdoors or indoors.
One complicating factor is aerosols. Aerosols are very small droplets that can be emitted when people are breathing and talking. The virus can spread through aerosols and travel farther than 6 feet.
Spread through touching surfaces with the virus
The coronavirus can live for hours to days on different surfaces. How long it survives depends on the material of the surfaces. Here is a list of how long the coronavirus can live on different materials.
Since the coronavirus can live on surfaces made of common materials for up to 5 days, it’s important to clean the surfaces in your home daily.
What you can use to get rid of coronavirus
Soap and water
Soap and water can help remove the coronavirus from surfaces and your hands effectively. They are the first line of defense.
The sodium hypochlorite in bleach is very effective at killing the virus. Leave the bleach to work for 10-15 minutes before wipe the surface with a clean cloth.
Surgical spirit is mostly made up of the alcohol ethanol and has been proven to kill coronavirus in about 30 seconds. Rub the surgical spirit over a surface with a cloth, and just leave it there. The alcohol will evaporate so you don’t need to wipe it off.
It’s not possible to live an entire isolated life during the pandemic, but what you can do is reducing the risk of exposure to all possible modes of transmission – droplets in the air and on surfaces, and smaller aerosols.
“Your job is to limit it as much as you can,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.
