Even as the number of positive COVID-19 cases continues to rise in the city, a new trend has left medical experts puzzled. While doctors had expected that TB patients would be more prone to the virus as their immune system is already weak, surprisingly only two such cases have been reported by the health department. Also, officials at the TB Hospital in Sewri said that while 14 of their staff members have tested positive, the infection has not spread to a single patient.

A senior official from the civic health department said that it might be too early to draw a conclusion but a study could be done to understand the correlation between the two. "So far, we have reports of two TB patients who have tested positive. However, there have been no deaths so far. One reason for the low numbers could be that we have given all TB patients medication for a month and have asked them to stay indoors," added the official.
