What Covid-19 Testing Taught Us – 2022 & Beyond - William D King

In March 2020, the world anxiously watched as cases of Covid-19, a novel coronavirus, were confirmed in countries around the world. As governments scrambled to enact containment measures and test potential cases, the true scale of the outbreak was still unknown. This blog post by William D King discusses what we learned from Covid-19 testing.

William D King on What Covid-19 Testing Taught Us – 2022 & Beyond

It’s been almost three years since the first case of Covid-19 was reported. In that time, we’ve seen the pandemic spread across the globe, infecting millions of people and killing hundreds of thousands. We’ve also seen an unprecedented global effort to develop vaccines and treatments for the virus.

One of the key elements in this fight has been testing, says William D King. Early on, there were few reliable tests available, and these were mostly reserved for those who were sick enough to be hospitalized. As more tests have become available, they’ve played an increasingly important role in our understanding of the pandemic and our efforts to control it.

There are two main types of Covid-19 tests: antibody tests and diagnostic tests. The latter is used to determine if someone currently has the virus. Antibody tests can show if someone has been infected in the past.

Diagnostic tests for Covid-19 are either molecular or antigen tests. Molecular tests detect viral RNA, while antigen tests detect proteins from the virus. Both types of tests can be performed with a swab of the nose or throat or with a saliva sample.

Antibody tests look for antibodies that are produced in response to an infection. These antibodies can be detected in blood or saliva samples.

One of the key lessons we’ve learned from testing is just how widespread the virus is. In many countries, only a small fraction of the population has been tested, but the results of those tests have shown that the virus is present in far more people than we previously thought.

This is important because it means that the true death rate from Covid-19 is probably lower than we thought. It also means that many people who have the virus are asymptomatic and don’t even know they have it.

As testing becomes more widespread, we’re likely to see even more cases of asymptomatic infection. This is why it’s so important to continue to follow public health guidelines even if you don’t feel sick.

Testing has also played a crucial role in identifying new variants of the virus, says William D King. These variants are of concern because they may be more contagious or more resistant to existing vaccines.

William D King’s Concluding Thoughts

In 2022, we had a lot to learn from what took place during the pandemic in terms of testing. According to William D King, we need to be prepared for anything and everything that could come our way, and doing so, will help keep us ahead of the game. Let’s take what we learned in 2022 and use it as a stepping stone into 2023 and beyond.
