A recent study has revealed that individuals infected with COVID-19 may carry the virus and remain contagious for as long as 37 days. As research into the global pandemic progresses, this information is crucial for understanding the virus’s behavior.
In a study conducted by a team of medical professionals in China, nearly 200 patients were analyzed, including 54 who succumbed to the disease. The researchers found that COVID-19 RNA (ribonucleic acid) persisted in respiratory samples from survivors for a median of 20 days following initial infection. Notably, the longest recorded period of viral shedding—the release of the virus from infected cells—was documented at 37 days.
The findings highlight significant implications for how long patients should be isolated and the recommendations for antiviral treatment duration, as noted by Dr. Jian Wu, a co-author of the study from the Beijing Medical Association.
As of now, COVID-19 has spread to 118 countries, infecting around 125,000 individuals since its emergence in Wuhan, China, in December 2019. Experts worldwide are actively seeking to comprehend the virus’s transmission methods and the necessary precautions to mitigate its spread.
Current estimates place the incubation period for COVID-19 at approximately five days. To protect themselves and vulnerable populations, health officials are urging individuals to refrain from travel and large gatherings, while many U.S. universities are transitioning to online classes for the foreseeable future. The U.S. Centers for Disease Control and Prevention recommends a minimum of 14 days of self-isolation for anyone who has been in contact with an infected person. Given the uncertainty of exposure, it’s wise for everyone, particularly those in public-facing roles, to consider self-quarantine, even if they are not exhibiting symptoms.
As more research emerges in the coming weeks and months, these findings underscore the importance of understanding the duration of contagion. The implications for both patient isolation and antiviral treatment guidelines cannot be overstated.
