25% of COVID-19 infected have no symptoms: but are contagious
US, WASHINGTON (ORDO NEWS) — Due to the large number of asymptomatic patients, coronavirus is difficult to overcome. According to some estimates by Robert Redfield of the US Centers for Disease Control and Prevention, the proportion of people who have no symptoms is 25%.
The worst thing is that the infected do not even know that they are currently actively spreading the virus, infecting their environment. It is possible that such a group of patients is responsible for the fact that today in the world there are more than one million patients.
Asymptomatic patients significantly complicate the containment of the pandemic. Another problem is the long incubation period of COVID-19. The first symptoms appear no earlier than 3-5 days.
WHO calls to wear masks for absolutely everyone, as they allow patients to not spread the virus. According to some testing in Iceland, the proportion of asymptomatic patients in general may be 50%.
