India has reported nearly 25,000 new coronavirus infections and its transmission rate is increasing for the first time since March, AP reported.

India’s infection numbers have skyrocketed since lockdown restrictions were eased. At the same time, testing has ramped up to more than 200,000 samples a day, compared to just a few hundred in March. Research by the Institute of Mathematical Sciences in Chennai shows that India’s virus reproduction rate ticked up in the first week of July to 1.19 after steadily falling from peak transmission of 1.83 in March.

Health experts say the true extent of the virus’s spread in India is unknown and more testing must be done, given its population of nearly 1.4 billion people.
