Sounding a note of caution, Union Health Minister Harsh Vardhan on Tuesday told the Rajya Sabha that the battle against Covid-19 is far from over, at a time when India's total tally has neared the five million-mark.

"I would urge all Members of Parliament that the coronavirus battle is still far from over. On one hand, when we are in an Unlock stage to revive the Indian economy, and have a balanced approach, it is important that sustained community support is ensured to control the spread of the virus and break its chain of transmission," Vardhan said in the Upper House.
