NEW DELHI, India (AP) — In June, India began using cheaper, faster but less accurate tests to scale up testing for the coronavirus — a strategy that the United States is now considering.

But government numbers suggest some parts of the country might have become over reliant on the faster tests, which can miss infections. Experts warn that safely using them requires frequent retesting, something that isn’t always happening.
