COVID-19 infections can reactivate dormant viruses already residing inside the human body, according to recent studies published in peer-reviewed journals including Nature and explored by outlets such as STAT and Genetic Engineering and Biotechnology News. Researchers investigating both acute and long COVID-19 have found that SARS-CoV-2 can wake up persistent pathogens like Epstein-Barr virus, offering new clues into the underlying mechanisms of chronic post-viral symptoms.
How SARS-CoV-2 Triggers Latent Pathogens
Most adults carry between 8 and 12 dormant viruses within their tissues, according to scientific data highlighted by IFLScience. When a person contracts COVID-19, the acute immune disruption and systemic inflammation can disrupt this delicate balance. According to findings covered by The Indian Express, the physiological stress of a coronavirus infection creates an environment where these sleeping viruses can reactivate and begin replicating.
However, the sheer global scale of the SARS-CoV-2 pandemic has amplified research into virus reactivation.
Connection to Long COVID Symptoms
The discovery that COVID-19 wakes up dormant viruses provides a compelling biological hypothesis for certain cases of long COVID.
According to reports from STAT, researchers are actively analyzing whether ongoing immune activation driven by these revived viruses contributes to the prolonged inflammation observed in long COVID patients.
Frequently Asked Questions
What are dormant viruses?
Dormant or latent viruses are pathogens that enter the human body, cause an initial infection, and then persist in a non-replicating state within cells, evading the immune system for years or decades.
Can other infections wake up dormant viruses?
Yes.
Are treatments available for reactivated viruses?
