Scientists are still studying whether ultraviolet (UV) light from the sun destroys the coronavirus.

Basic soap-and-water scrubbing can, in fact, kill bacteria and viruses like coronavirus. You can use regular dish soap and hot water to clean surfaces (be sure to rinse with plain water) before applying a disinfectant to kill even more germs.

Researchers at the University of Washington's Institute for Health Metrics and Evaluation, publisher of a popular coronavirus model, are among those who attribute declining cases to vaccines and the virus's seasonality, which scientists have said may allow it to spread faster in colder weather.

The team found that B. 1.1. 7 is more deadly than previous variants for all age groups, genders and ethnicities. “This provides strong evidence that there indeed exists increased mortality from the new strain,” says Henrik Salje, an infectious-disease epidemiologist at the University of Cambridge, UK.
