We start the month of February with a very informative articles from the New York Times about car use and the spread of Covid-19. There have been a lot of discussions or discourse, even arguments, about private car use or shared vehicles (e.g., Grab) as people have apparently chosen these over public transport in many parts of the Philippines. For one, there is still a limited supply of public transport as government tries to take advantage of the situation to implement their rationalization and modernization programs.

The following article is from the US but the principles presented particularly about air flow and the potential spread of the virus inside a car are factual and apply in a general manner to other situations including ours. It is important to have an appreciation of the science behind air circulation and how it relates to the potential infections.

Anthes, E. (January 16, 2021) “How to (Literally) Drive the Coronavirus Away,” New York Times, https://www.nytimes.com/2021/01/16/health/coronavirus-transmission-cars.html [Last accessed: 2/2/2021]

The common misconception appears to be that using private vehicles automatically helps spread the coronavirus. The science tells us it is not as simple as that (i.e., using your own vehicle will lead to your and your family being infected). While private vehicles are not the proverbial suit of armor vs. Covid-19, their proper use might give better chances compared to crowded and/or poorly ventilated public utility vehicles. Walking and bicycles, of course, are most preferred but that’s a topic for another article.
