The strength of the immune response was directly related to the percentage of genes derived from African ancestors, said senior researcher Luis Barreiro. He's an assistant professor at the University of Montreal's Department of Pediatrics and researcher at the Sainte-Justine University Hospital Center in Montreal.

"Basically, the more African you have in your genome, the stronger you're going to respond to infection," Barreiro said.

But a strong immune response uses inflammation to attack and defeat infection, he said.

Too much inflammation can cause chronic high blood pressure, damage organs such as the heart, and increase susceptibility for autoimmune diseases such as lupus and Crohn's disease, Barreiro said.

"The immune system of African-Americans responds differently, but we cannot conclude that it is better, since a stronger immune response also has negative effects," he said.

Genetic differences between blacks and whites (with Neanderthal DNA) due to evolution, interbreeding and natural selection appear to be behind this difference in immune response, Barreiro said.

Researchers identified thousands of genes that showed race-based differences in a person's genetic response to infection.

High temperature and high relative humidity significantly reduce the transmission of COVID-19, respectively, even after controlling for population density and GDP per capita of cities, they wrote.

Another study published March 1 in the Journal of Hospital Infection examined the lifespans of various human coronaviruses on many different surfaces.

The study authors found that spikes in temperature made a difference in the lifespans of coronaviruses across surfaces.

For example, an 18-degree Fahrenheit (32-degree Celsius) jump, from 68 degrees to 86 degrees, decreased how long SARS lasted on steel surfaces by at least half.

This may be because some coronaviruses (and the flu) have a viral envelope: a layer of fat that protects viral particles when traveling from person to person in the air. But that sheath can dry out faster in warmer temperatures, disabling the virus.
