Many people are seeking definitive answers to recurring questions about how the coronavirus transmits from one person to another and how to maintain safety and prevent COVID-19 infection in both closed and open spaces.
**Key Warnings**
Dr. Oliver Morgan, an epidemiologist and head of COVID-19 response at the World Health Organization (WHO), was a guest on the 40th episode of the “Science in Five” program, presented by Fismita Gupta Smith. He stated that COVID-19 transmission occurs through inhaling respiratory droplets emitted by an infected person, or by touching the nose, mouth, or eyes with contaminated fingers. He emphasized the essential adherence to WHO recommendations to avoid three main things: being in crowded places, close contact with others, and remaining in poorly ventilated indoor locations.
**Outdoor Air and Poor Ventilation Risks**
Dr. Morgan explained that the WHO recommends holding meetings and gatherings outdoors whenever possible, as the virus can spread when attendees talk, laugh, or sing. It is crucial to ensure good airflow, even in outdoor settings. He noted that when meetings or gatherings occur indoors, the risk of transmission increases significantly without good ventilation. Therefore, it is important to be aware that there is always a risk of infection during indoor gatherings, similar to the risk faced by people living together in the same household who have close contact for extended periods.
**Guidelines for Indoor Locations**
To prevent infection and keep people safe when necessary meetings occur indoors, Dr. Morgan advised several measures. These include opening doors and windows, if possible, to promote airflow in the room, along with wearing protective masks. A physical distance of at least one meter should be maintained between individuals whenever feasible.
He also stressed the importance of regular handwashing with soap and water, as the virus can exist on surfaces. Moreover, getting vaccinated against the coronavirus whenever possible is emphasized as an essential practice for everyone.
**Prevention in Open Spaces**
Regarding precautions while in open spaces, Dr. Morgan recommended following the same protective measures as in closed settings, including wearing masks and maintaining a physical distance of at least one meter. Frequent handwashing is also advised, to prevent any viruses from various surfaces.
