HAVANA, Cuba, Jul 30 (ACN) Dr. Francisco Duran, Cuba's national director of epidemiology, warned Thursday that asymptomatic super spreaders are the worst threat in closed places to infect with the coronavirus SARS-CoV-2, which causes COVID-19.
Duran pointed out that many of the recent events reported which have raised the contagion curve in the country have occurred precisely in closed spaces.
As confirmed by scientists, airborne viral load can reach critical concentrations in closed, poorly aired environments, especially when an infected super spreader is present, said the expert, who never forgets to reiterate the importance of individual and collective prevention.
In this sense, he quoted a new study published in the American journal JAMA Network Open, which emphasizes that a strict use of masks can prevent the spread of the coronavirus SARS-CoV-2.
Experts say that most people infected with a typical viral load do not fill the air with coronavirus-infected respiratory droplets and therefore the risk of spreading the pathogen tends to be low.
However, a super spreader when coughing can often fill a poorly ventilated room with up to 7.4 million copies of the coronavirus per cubic meter of air, he indicated.
The implication of these findings for everyday life and the workplace, Dr. Duran said, is that people can be at high risk for infection if they stay in a small room for more than a few minutes.
