NEW YORK (AP) — No quick dispatching of disease investigators. No televised news conference to inform the public. No timely health alerts to doctors.

In the midst of a hantavirus outbreak that involves Americans and is making headlines around the world, the U.S. government’s top public health agency, the Centers for Disease Control and Prevention, has been uncharacteristically missing in action, according to a number of experts.

To President Donald Trump, “We seem to have things under very good control,” as he told reporters Friday evening.

To experts, the situation aboard a cruise ship has not spiraled because, unlike COVID-19 or measles or the flu, hantavirus does not spread easily. It has been health experts in other countries, not the United States, who have been dealing primarily with the outbreak in the past week.

“The CDC is not even a player,” said Lawrence Gostin, an international public health expert at Georgetown University. “I’ve never seen that before.”
