Dr. Patolia said he was surprised by the study finding that one in 400 people in the general population could be asymptomatic carriers of COVID-19.
“Also, nursing home patients are more at risk of complications of COVID, and I expected that they would have a higher rate of symptomatic disease as compared to [the] general population,” said Dr. Patolia. He was also surprised by the high rate of asymptomatic infections in travelers.
“Physicians should be more aware about the asymptomatic carrier rate, particularly in travelers and nursing home patients,” he noted. “Travelers carry high risk of transferring infection from one region to another region of the world, and physicians should advise them to get tested despite the absence of symptoms,” Dr. Patolia emphasized. “Similarly, once any nursing home patient has been diagnosed with COVID-19, physicians should be more careful with the rest of the nursing home patients and test them despite the absence of the symptoms,” he added.
Dr. Patolia also recommended that pregnant women wear masks to help prevent disease transmission when visiting a doctor’s office or labor unit.
Looking ahead, there is a need for cheaper at-home testing kits so that all vulnerable populations can be tested fast and frequently, Dr. Patolia said.
The study was supported by the National Natural Science Foundation of China. The researchers had no financial conflicts to disclose. Dr. Patolia has disclosed no relevant financial relationships.
