I still don't understand the push for blanket COVID-19 testing of the general population.
You could go in to get a test today, test negative and then go out and contract the infection the next day (if you were exposed to someone who had the infection).
1. Unless you are severely ill, testing for COVID-19 does not change your treatment. Healthy people with mild symptoms will get the same advice as those who get the flu: stay home, stay hydrated, and take Tylenol. If you feel sick, prevent spreading your infection to others through self-quarantine for 14 days. Regardless of whether or not you may have a positive diagnosis of COVID-19, we can all do our part by practicing responsible social distancing.
2. Going to get tested could put you at risk for catching or spreading COVID-19. Patients are crowding waiting rooms to request testing, leading to a breakdown in social distancing that exposes more people to the spread of COVID-19. Even the test itself can spread infectious particles, as patients undergo the unpleasant process of having a nasopharyngeal swab stuck up their nose and often end up coughing or gagging.
3. Current tests can still miss infections. A recent study found that nasal swab testing in China missed 37% of COVID-19 cases, while throat swabs missed up to 68%. In the U.S., there are multiple different tests with varying degrees of accuracy, and the number of patients who test negative but actually have COVID-19 remains unknown. In the early stages of infection, it’s possible for your test to be falsely negative, which could lead to a false sense of confidence. A negative test does not change your risk of becoming infected, and everyone must continue to practice responsible health precautions.
4. In most regions of the U.S., COVID-19 is so widespread that testing is no longer helpful for containment. During the initial “containment” phase of an outbreak, testing is critical for finding isolated cases and tracking down contacts who may have been exposed. Done properly, like in South Korea and Singapore, early testing prevents an outbreak like COVID-19 from spiraling out of control. Unfortunately, our own efforts to ramp up testing have come far too late – we missed the opportunity to trace and contain COVID-19. Now that the coronavirus has become so widespread, social distancing, rather than testing, is the most effective strategy for fighting this pandemic.
5. Unnecessary testing could overwhelm our health care system and deprive resources from critically ill patients. As we face one of the most severe flu seasons of this decade, hospitals are already operating at close to maximum capacity. With impending shortages of beds, masks, and ventilators, it may only be a matter of time before American doctors are forced to make the same extraordinary rationing decisions being made by their Italian colleagues.
