Experts are trying to figure out why the coronavirus is so capricious. The answers could determine how to best protect ourselves and how long we have to. The coronavirus has killed so many people in Iran that the country has resorted to mass burials, but in neighboring Iraq, the body count is fewer than 100. The Dominican Republic has reported nearly 7,600 cases of the virus. Just across the border, Haiti has recorded about 85. In Indonesia, thousands are believed to have died of the coronavirus. In nearby Malaysia, a strict lockdown has kept fatalities to about 100.
