Delta variants can be detected by genome sequencing

The virus tests used to determine if a person is infected with COVID-19 are not designed to know which variant is causing the infection.

NS Delta variant According to the Centers for Disease Control and Prevention (CDC), it is the predominant COVID-19 strain in the United States.

As highly contagious strains spread rapidly across the country Many people I’m wondering how I can tell if I’m infected with a delta variant.


Is there a COVID-19 test specific to the delta variant?

Source of information


Yes, delta variants can be detected by genome sequencing, but it is not a test taken at the clinic.

What we found

According to the CDC, there are two types COVID-19 test Available to test current or past infections — Virus testing When Antibody test..

“A virus test checks a sample through the nose or mouth to see if it is currently infected with the virus that causes COVID-19. A virus test can be done in the laboratory, at the test site, at home, or elsewhere. It can be done with. Two types of virus testing are used. Nucleic acid amplification test (NAAT) When Antigen test“The CDC Website..

When it comes to detecting whether a person has a delta variant, the Texas Department of Health (DSHS) states that the information “may not be immediately available.”

“The viral tests used to determine if a person is infected with COVID-19 are not designed to know which mutant is causing the infection,” Texas DSHS said. Said above. Website..

According to Texas DSHS, detection of delta variants and other variants of COVID-19 requires a special type of test called “genome sequencing”, but due to the large number of cases of COVID-19 in the United States, all The virus sample does not perform the sequence. ..

“”Genome sequencing Scientists identify SARS-CoV-2, the virus responsible for COVID-19, and monitor how it transforms into new variants over time, and these changes characterize the virus. Understand how it affects and use this information to better understand how the virus changes. According to the CDC, it affects your health.

Dr. Gabe Kelen, director of emergency medicine at Johns Hopkins Medicine in Baltimore, confirms that virus testing used in doctors and pharmacies is common.

“They detect the presence of SARS-CoV-2, a viral infection. It doesn’t identify it, which means it doesn’t tell you which strain,” Keren said. “Major laboratories like us, the CDC, and most state health departments have the ability to actually sequence these samples.”

According to Texas DSHS, delta variants now make up the majority of COVID-19 cases in the United States, so “a positive test result is likely to indicate infection with the delta variant.”

Dr. Ameshua Darja, a senior scholar at the Johns Hopkins Health Security Center, supports the Texas DSHS statement.

“For all purposes and purposes, if you are infected with COVID-19 in the United States today, you can consider it to be a delta mutant because it is the predominant version of the virus here. “Dr. Adalja told VERIFY.
