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.
I took the photo as we were driving up to Antipolo one morning this month when the opportunity presented itself for a quick photo of Metro Manila:
This serves as a reminder for those working to improving air quality in Metro Manila and elsewhere. It has already been established that much of the air pollution in Metro Manila and its adjacent areas can be attributed to mobile sources (i.e., motorised transport). A reduction of motor vehicle use, particularly cars, combined with more efficient engines and cleaner fuels should be lead to significant air quality improvements and, ultimately, an improvement in the quality of life. Of course, there should be parallel efforts to improve facilities for walking and cycling, and implementing the mass transit projects that will carry most people between the origins and destinations regardless of the distances.
Here’s to the approaching 2019 and the optimism that comes with the New Year!
Manigong Bagong Taon sa lahat!
