BENGALURU/NEW DELHI—India recorded more than 4,000 COVID-19 deaths for a second straight day on Thursday, while infections stayed below 400,000 for a fourth day, though the virus has become rampant in rural areas where cases can go unreported due to a lack of testing.
Experts remain unsure when numbers will peak and concern is growing about the transmissibility of the variant that is driving infections in India and spreading worldwide.
