We are not scientists or public-health experts but we crawl the world wide web for information, text, and literature about the COVID-19 disease and the virus, SARS-CoV2, that causes it from leading scientists, experts and journalists.
Six months into this Covid-19 pandemic, a growing consensus among experts is developing that people catch Covid-19 through close-up, person-to-person interactions for an extended periods of time which usually happens in crowded events, poorly ventilated areas and places where people are talking loudly or are singing. The so-called attack rate – the percentage of people who were infected in a specific place or time – can be very high in crowded events, homes and other spaces where lots of people are in close, prolonged contact.
One important factor in transmission is that talking, breathing, and singing produce respiratory bits of varying sizes that can disperse along air currents that can be directly inhaled by people nearby.
Getting Covid-19 from contaminated surfaces is rare while short encounters with people outdoors are unlikely to cause the spread of the SARS-Cov2. Being outside is generally safer because viral particles dilute more quickly.
