The CDC has released updated guidelines for the coronavirus, with one of the largest changes highlighting the fact that the virus is able to spread easily with the help of droplets or small aerosol particles that are released when a person talks, coughs, sings, sneezes, or breathes.
Airborne viruses, with COVID-19 included, are notorious for their ability to spread at a fast face in crowded and environments with poor ventilation. The particles can cover large distances after release, and they are deemed to be the prime infection vectors.
New data has also revealed that droplets and airborne particles can remain suspended in the air and are able to cover distances larger than 6 feet. Indoor activities where activities like choir practice, sports, and fitness take place favor the spread of the virus, even more so if the building doesn’t have a proper ventilation system.
The social distancing rules are also harsher. If previous guidelines advised people to stay at a distance of six feet, the new advice notes that a distance of a minimum six feet is the bare minimum, and a greater distance should be kept whenever possible.
It is also advised to wear a mask and use disinfectants as often as needed to reduce the risk of contracting or spreading a disease. Those who feel seek are advised to stay at home in self-isolation, and air purifiers should be employed to minimize the potential risks.
Several scientists have argued for months that the virus can spread easily via airborne transmission, with early reports appearing at the start of April. An open letter was sent to the World Health Organization in July, arguing that the organization should take the spread of the virus via droplets into account more seriously.
The new CDC guidelines have been praised by several health experts, as they will contribute more effectively to the fight against COVID-19.
