The U.N. health agency says two patients with hantavirus and one suspected of infection were evacuated from a cruise ship at the center of a deadly outbreak. Two of the patients arrived at Amsterdam's airport Wednesday evening and were driven off in ambulances. The ship departed from Cape Verde and headed to Spain's Canary Islands. The World Health Organization says eight cases have been recorded, with five confirmed by lab tests. Three people have died. Two Argentine officials investigating the origins of the outbreak say the government's leading hypothesis is that a Dutch couple contracted the virus during a bird-watching outing before boarding.

A new variant of COVID-19 is circulating in parts of the world and may be driving an increase in cases in the eastern Mediterranean, Southeast Asia and western Pacific regions. The World Health Organization said Wednesday the new variant called NB.1.8.1 is increasing globally and in mid-May had reached nearly 11% of sequenced samples. Current vaccines are expected to remain effective and there's nothing to suggest that the disease associated with the variant is more severe. Airport screening in the United States has detected the new variant in international travelers arriving in California, Washington state, Virginia and New York.

Five years after the virus that causes COVID emerged in China it still holds some mysteries. The disease has killed an estimated 20 million people globally, according to the World Health Organization, and thousands are still dying every year. But scientists still aren't clear where it came from, and they are still trying to understand what causes long-term symptoms called long COVID. And while vaccines have helped dramatically reduce severe disease and death from COVID, the virus mutates so quickly researchers have struggled to find a vaccine that stops the spread.

Updated COVID-19 vaccines are on their way. The Food and Drug Administration approved new shots from Pfizer and Moderna on Thursday, and the companies are set to begin shipping millions of doses. The shots are cleared for adults and children as young as 6 months, and health authorities hope far more Americans get them this year. Vaccinations could begin in days, as a summer wave of COVID-19 continues. Authorities say anyone who's recently been infected can wait three months after recovering to get vaccinated.
