The percentage of infection with coronavirus from asymptomatic carriers in the chain transmission, is an open question that requires further study. This was during an online conference on Twitter June 9, said the Executive Director of the world health organization for emergency situations Mike Ryan.
So who responded to the wave of skepticism that rose after the statement of the technical program Manager Maria van Kerkhove. She said on 8 June that the cases when people with asymptomatic course of the disease passes the infection to another person, is very rare.
Van Kerkhove, which also participated in the conference suggested that it was not understood because it was only on certain model studies and not on the situation in the world as a whole. “I don’t mean the policy of the who, and was just trying to systematize what we know,” she said.
Studies show that about 16% of the population can carry COVID-19 without symptoms, some scientists suggest that up to 40% of the global transmission can occur from asymptomatic individuals, said technical Manager. Who proposes to divide those who did not manifest obvious signs of the disease during the asymptomatic and presymptomatically (those who have symptoms develop later) of the media, it could also cause confusion, suggested van Kerkhove.
