Two Iranian scientists fell ill in late May, and they grew sicker and ended up in the intensive care units of hospitals in two different cities nearly 400 miles apart. Then, they both died within days of each other.
They both graduated from Iran’s top universities — young, healthy and athletic. One of them, Ayoub Entezari, was an aeronautical engineer who worked for a military research center, and the other, Kamran Aghamolaei, was a geologist.
