The use of tear gas may increase the spread of the virus due to coughing and lung damage.
Smoke and pepper spray may also increase its spread.
Shouting and speaking loudly, which are common to both violent and non-violent protests, may also cause infections at distances greater than 6 feet (1.8 m).
Research has found that the share of infections due to a single infected person in a choir can be almost 90%, and that just a few contagious people can infect hundreds of susceptible people around them.
Outdoor events may have a substantially lower risk of spreading the disease than indoor ones, and the "transient" moments of people moving around may be less-hazardous than longer durations of proximity.
