COVID-19: propagation of risk via the air has been underestimated so far? – Naturopathy Naturopathy Specialist Portal

How strong is the risk of corona is a virus on the air?

To avoid the spread of COVID-19, it is important to understand the role of the airborne transmission of infectious droplets, especially if they come from an infected Person, which have about 1.5 meters distance. A research group called now by the health authorities, the awareness of the Transmission of COVID-19 to float on the air, as this results in a greater risk than previously thought.

In the case of the current joint investigation by the Queensland University of Technology and the Chinese Academy of Sciences, it was found that the role of the airborne transmission of viral droplets in the case of COVID-19 was strongly underestimated. The results of the study were published in the English journal “Environment International”.

Would the Transmission of viable virus droplets through the air, underestimated?

The national health authorities for the control of the pandemic be responsible, be hampered by the fact that it reports the research results on the Transmission of viable virus droplets through the air don’t recognize, which were conducted after the SARS outbreak in 2003, the researchers.

Spread of COVID-19 through the air?

Now is the ideal time can spread to explore how viruses due to the air flow, since there are many Similarities between the Coronavirus, which SARS has caused, and the COVID-19-Coronavirus. Therefore, it is the researchers found to be very likely that COVID-can-spread 19 on the air.

Several cases of contact Transmission have already occurred

The analysis of the initial pattern of spread of COVID-19 in China shows several cases of a non-contact Transmission, especially in areas outside of Wuhan, says the research group. On numerous cruise ships, where thousands of people were infected, were many of the infections after the passengers have had to isolate in their cabins, and although improved hand hygiene was introduced. Therefore, the ventilation system could have widespread infectious air between the cabins, conclude the researchers.

Transmission of corona virus through the air has already been confirmed

“We know that the predecessor of Covid-19, SARS.CoV-1, during the outbreak in 2003, over-the-air has distributed. Several studies have explained this mode of Transmission in Prince of Wales Hospital in Hong Kong, as well as in health-care facilities in Toronto, Canada, retrospectively,“ explains Professor Lidia Morawska from the Queensland University of Technology, in a press release.

Increased risk in interior spaces?

A Review of the world health organization in 2009 found evidence that viral diseases in indoor environments due to Aerosol or airborne transmission to be propagated over large distances and it can come in a short period of time to the accumulation of infections.

The smallest virus droplets transmitted through the air

The liquid part of virus droplets began to evaporate immediately after the Exhale and some of the droplets were so small that they could move in the air currents, and not fell to the ground, as in the case of larger droplets actually the case.

On the air-spreading viruses are difficult to prove

“Such small droplets can carry away your virus content of dozens of meters of the infected Person,” says Morawska. It is difficult over-the-air expansion was to prove the end of the virus directly, since it requires the knowledge of the air flow, as well as Collecting samples over a long period of time is required.

How can we protect ourselves?

The research group asks that health authorities need to take precautions to reduce the Transmission over the air. These arrangements include, for example, rooms of the increased ventilation of the interior and the use of natural ventilation. Air circulation should be avoided, as well as the stay in the direct air stream of another Person. It should be also ensured that as little as possible of people in the same environment. In nursing homes, hospitals, shops, offices, schools, Restaurants, and on cruise ships, adequate ventilation should be implemented.

Further research is needed

More research work must be carried out for the air transfer. The probability of the spread of COVID-19 airborne droplets, must be taken seriously and the appropriate protective measures should be taken. So far, the air transfer as a method of propagation has been largely ignored, criticize the researchers. (as)
