Understand the Coronavirus Spread, Can It Over the Air?



Understand the Coronavirus Spread, Can It Over the Air? - Aside from droplets or contact with people who are favorable for the coronavirus, or through items exposed to the virus, fears of emerging infections also spread through the air. How are the facts spread?

Respiratory infections caused by the coronavirus or COVID-19 are indeed transmitted through droplets of various sizes and physical contact. The most common cases in the coronavirus are transmitted through respiratory and touch drops.

In an analysis of 75,465 cases of COVID-19 in China, there were no reports of airborne transmission. Transmission of droplets occurs when a person is in close contact or about 1 meter away from someone who has respiratory symptoms, such as coughing or sneezing and is therefore at risk of mucosa (mouth and nose) or conjunctiva (eye) being exposed to potentially infective respiratory drops.

Transmission can also occur through fomites in the environment around an infected person. Therefore, transfer of COVID-19 can occur through direct contact with an infected person and indirect contact with surfaces in the immediate environment or with objects used in an infected person, such as a stethoscope or thermometer.

Reporting from www.who.int, the transmission of COVID-19 transmission through the air can be made possible under special conditions and settings where supporting procedures or treatments that produce aerosols are carried out, namely endotracheal intubation, bronchoscopy, open suction, administration of nebulization, manual ventilation before intubation, turning the patient into a prone position, disconnecting the patient from the ventilator, non-invasive positive pressure ventilation, tracheostomy, and cardiopulmonary resuscitation.

There is some evidence that COVID-19 infection can cause intestinal infections and is in the stool. However, to date, only one study has bred the COVID-19 virus from a single fecal specimen. There have been no reports of fecal transmission, COVID-19 oral infection to date.

A recent publication in the New England Journal of Medicine has evaluated the persistence of viruses from the coronavirus. The discovery of coronaviruses in aerosol particles for up to 3 hours does not reflect the clinical setting, in which aerosol-producing procedures are carried out, that is, aerosol-producing procedures that are experimentally induced.

As a result, based on available evidence, including the most recent publications mentioned above, WHO calls for precautions to be taken for people caring for COVID-19 patients. WHO continues to recommend airborne precautions for circumstances and arrangements where aerosol-producing procedures and support treatments are carried out by a risk assessment.

This recommendation is consistent with other national and international guidelines, including those developed by the European Society of Intensive Care Medicine and the Society of Critical Care Medicine, which are currently used in Australia, Canada, and the United Kingdom.

The current WHO recommendations emphasize the importance of using all rational and appropriate PPE, not just masks that require the right behavior and from health workers, especially in cleaning procedures and hand hygiene practices.

WHO also recommends training staff on these recommendations, as well as adequate procurement and availability of PPE needed and other supplies and facilities. WHO continues to stress the importance of hand hygiene, respiratory etiquette, and environmental cleaning and disinfection, as well as the importance of maintaining physical distance and avoiding close and unprotected contact with people with symptoms of fever or breathing.
