What I Know about COVID-19

This article is the collection of knowledge / thoughts about COVID-19 that I find relevant to my everyday life.

Getting it: masks work. Not perfectly. This is a good illustration on El Pais.

Incubation period: average of 5 days.

On average, symptoms showed up in the newly infected person about 5 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14. 

When Contagious: most contagious 1 to 2 days BEFORE one is sick.

Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick. 


If anyone has additional articles that I should incorporate, please email me at covid@nikitab.com and I will review them.


  • After someone travels, when should they get tested to assess if they picked it up while traveling?
