The coronavirus is finding

Store USA new victims worldwide, in bars and
restaurants, offices, markets and casinos, giving rise to
frightening clusters of infection that increasingly confirm
what many scientists have been saying for months: The virus
lingers in the air indoors, infecting those nearby.
If airborne transmission

Shop is a significant factor in the pandemic,
especially in crowded spaces with poor ventilation, the
consequences for containment will be significant. Masks may
be needed indoors, even in socially distant settings.
Health care workers may need N95 masks that filter out even
the smallest respiratory droplets as they care for
coronavirus patients.
Ventilation systems in schools, nursing homes, residences
and businesses may need to minimize recirculating air and
add powerful new filters. Ultraviolet lights may be needed
to kill viral particles floating in tiny droplets indoors.
The World Health Organization has long held that the
coronavirus is spread primarily by large respiratory
droplets that, once expelled by infected

cigarettes people in coughs and sneezes, fall quickly
to the floor.
But in an open letter to the WHO, 239 scientists in 32
countries have outlined the evidence showing that smaller
particles can infect people and are calling for the agency
to revise its recommendations. The researchers plan to
publish their letter in a scientific journal.
Even in its latest update on the coronavirus, released June
29, the WHO said airborne transmission of the virus is
possible only after medical procedures that produce
aerosols, or droplets smaller than 5 microns.
