The fight against COVID-19 isn’t over

With lack of widespread COVID vaccination and the emergence of new variants, it’s critical we make use of all the tools we have to fight the virus—including rapid antigen testing.

COVID-19 upended our lives, changing the way we live, work, and socialize. After more than a year of quarantining, social distancing, masking, and relentless handwashing, people are anxious to return to normal. 


As some nations are starting to ease restrictions and open back up, new strains of the virus are wreaking havoc around the world. We must remain vigilant with pandemic best practices and rigorous serial testing to prevent the spread because the virus is mutating—and the pandemic isn’t over yet.


Why viruses mutate—and what it means for us


Viruses mutate all the time through a process called antigenic drift—quite simply, the virus makes an error while copying itself and a new mutation is born. Most of the time, these mutations rise and fall quickly and are no cause for concern, likely even going unnoticed the vast majority of the time.


These changes will give a virus a competitive edge. For example, a mutation could make a particular strain of virus better able to attach to human cells, making it more contagious. Or it could make the virus multiply more quickly in the human body, building up heavy loads of the virus and allowing it to spread from person to person earlier in the course of infection.


Or, in the case of the Delta variant, it could do both those things.


A new strain takes hold


In October 2020, the World Health Organization detected a new strain of the SARS-CoV-2 virus which causes COVID-19


Within six months, the new strain, the Delta variant, was officially labeled a Variant of Concern (VOC).


By July 2021, the Delta variant had made its way to 100 countries. India had surpassed 400,000 deaths and set records for the most daily deaths, many of them driven by a surge caused by the Delta variant. In the United States, the Delta variant had been recorded in all 50 states and was the dominant strain, representing about 52% of all new cases and as many as 80% or 90% in hotspots.


There is still much to learn about the Delta variant, but preliminary studies are alarming. One study in Scotland, for example, showed people infected with the Delta variant were twice as likely to need hospitalization compared to people infected with the Alpha variant (the strain most prominent before the Delta variant).


Unfortunately, the Delta variant isn’t the end of the story. The World Health Organization is currently tracking at least four other Variants of Interest (VOI), including the Lamba variant, which has been found in 29 countries and is already the cause of more than 80% of cases in Peru.


It’s clear the fight against COVID isn’t over yet.


Rapid antigen testing—a powerful tool in the fight against COVID-19


As we know by now, some of the most effective ways to prevent the spread of disease are through methods like handwashing, social distancing, and wearing masks or face coverings.


Some countries now also have access to vaccines. So far studies suggest the vaccines do offer protection against the different strains, although the level of protection may vary; for example, a fully vaccinated person may still become infected with the Delta variant, but their symptoms would be much more mild.


However, we cannot fully rely on the vaccine to protect. Only about 25% of the world’s population has gotten at least one dose of the vaccine—a far cry from the 70% to 90% experts say is needed in order to achieve herd immunity. Higher vaccination rates are concentrated in wealthier countries; low-income countries hover around 1% of the population having received a first dose.


Fortunately, rapid antigen tests have emerged throughout the pandemic as an extremely effective and reliable way to mitigate the spread of disease. 


Rapid antigen tests analyze samples, oftentimes via nasopharyngeal swabs, to detect proteins specific to COVID-19. They’re designed to detect high viral loads, which occur in the body when a person is most infectious. According to the latest report published by the UK government in July, the Innova test can detect the latest Delta variant, B.1.167.2 and Delta Plus Variant B.1.617.2.1 in addition to being able to detect previously identified variants including Alpha, Beta, Gamma and Kappa as shown in recent studies. 


These tests are also very convenient and accessible. They don’t require special equipment and they don’t have to be sent to a lab. They produce results in 30 minutes or less. This allows people to safely conduct these tests from the comfort of home and get quick and reliable information on whether they’re virus-free—or whether they need to start isolating right away.


Rapid antigen testing—most effective when used in serial testing


Rapid antigen testing is at its most effective when used as a regular part of COVID-19 safety practices, such as in the UK where testing twice a week is advised, even if a person doesn’t feel sick. To this end, the UK has made tests available for free for much of the population. Frequent testing is recommended in part because the virus has a median of 5 days incubation period when the virus is not live and not detectable and that rapid antigen tests have proven critical when it comes to detecting asymptomatic cases. Studies show 1 in 3 people infected with COVID-19 never display symptoms. Because they don’t know they’re infectious, these asymptomatic individuals can spread the disease without even realizing it—a particularly concerning threat considering how easy it is to spread and catch the Delta variant. Making serial testing a regular and accessible option means those cases can be identified and appropriately managed, breaking the chain of disease transmission—and saving an untold number of lives.


A weapon in the fight against COVID


The vaccine is helping us make progress against COVID-19. With the emergence of new variants and the lack of widespread access to the shots, it is critical we continue to use all the tools in our arsenal to protect ourselves and each other from the virus. With fast, accurate results, rapid antigen testing is one of the best tools available.
