How COVID-19 Is Detected Or Confirmed
One of the biggest issues with detecting COVID-19 in a patient is that it presents much like the common cold. To combat this, researchers across the globe have been scrambling to come up with a way to test for the presence of the virus, and this has resulted in several different testing methods. One of the best ways to check for the virus isn’t to see if you can find the virus in a person’s body—it’s to find the antibodies the body produces to fight the infection. The tests that look for antibodies are called serological tests, and a firm in Singapore may have perfected a means of conducting this type of test to find COVID-19.
Antibody tests are probably the fastest and easiest way of detecting the presence of COVID-19, but it isn’t the only way. There are tests currently being used around the world, which look for the virus’ genetic information in a person’s saliva, mouth, nose, and anus. These tests use the polymerase chain reaction (PCR) method, which is a process in molecular biology that rapidly produces billions of copies of DNA for study. While these tests can detect the presence of COVID-19, they cannot identify people who were infected and ultimately cleared of it.
Who Is At Risk
There is no known immunity to COVID-19, which means that everyone is at risk of catching and spreading the infection. That doesn’t mean this is a perfect time to panic; just because you might become infected, doesn’t mean you’re going to fall over dead in a few hours. COVID-19 can be dangerous, but like most infections, certain portions of the population are more at risk than others. Young children, healthcare professionals, the elderly, and people with a compromised immune system are the ones who are most at risk of becoming seriously ill from COVID-19.
When a healthy adult contracts the virus, there’s a possibility that they will not show any symptoms at all, and won’t get sick. This is one of the reasons the virus has managed to escape the confines of Wuhan, China, to infect the world. Infected people who are asymptomatic become unknown carriers, and even when an otherwise healthy adult does show symptoms, they are often mild and comparative to the common cold.
