The world health organization underestimates the risk of the spread of coronavirus in the air. Concerned scientists from different countries. They believe that the virus-containing tiny droplets of liquid that are allocated when the infected cough or sneeze can stay in the air much longer than suggested by who. Speech in particular goes about confined or poorly ventilated areas, and on public transport. That is a possible transfer of coronavirus airborne droplets may explain why the infection was spread with great speed during the rehearsals of the choir, or Lunches with a large number of invited guests.
Paul Edelstein, an expert in the field of pathology, the University of Pennsylvania: “I agree that you should pay attention to all the ways of transmission of coronavirus in the air, and that is better to ventilate the room. It is reasonable. The only thing that was not mentioned in the statement of these scholars is the need to arrest the primary infection source. In other words, to prevent transmission to people.”
Open letter to the who guidelines, which States about the risk of transmission of coronavirus by airborne droplets, the document was signed by 239 researchers from 32 States.
The Royal Society, the leading scientific society of great Britain, also issued a statement with a strong recommendation to wear all protective masks. The call was announced after two new reports have provided evidence of the effectiveness of the mask directly to the person who wears it, because it protects the owner.
Paul Edelstein, an expert in the field of pathology, the University of Pennsylvania: “wearing a mask helps prevent transmission of droplets of two types, large and small. Before you disintegrate into microparticles in the air (from infected people) first gets drops of larger size, which captures the mask”.
Experts of the world health organization study made by international group of scientists offer to admit that the new coronavirus can be transmitted by airborne droplets, and include this possibility in its recommendations. This was at the briefing in Geneva, said a technical expert who Benedetta of Allegranzi.
