(CNN) — Since the first sign of an outbreak, the reminders have come from government officials, health agencies and plenty of experts: There’s no reason to worry. Don’t panic. It’s under control.
“We have this under control, and we’re not worried about it,” US Health and Human Services Secretary Robert F. Kennedy Jr. said at a briefing Monday when asked about the hantavirus outbreak that has moved from cruise ship to quarantine.
“The thing about this one,” President Donald Trump said in the same briefing, “it’s much harder to catch. It’s been around for a long time. People are very familiar with it. I hope it’s fine.”
In a society with still-fresh memories of the loss and disruptions of the Covid-19 pandemic, federal and state officials have repeatedly assured the public that the hantavirus – even the Andes strain, which can be transmitted from person to person – is not the menace the world was facing six years ago.
It’s true that it’s no Covid. Although the illness the Andes virus causes can be serious and even deadly, it’s not as contagious as measles or even the flu, which means it may be contained more easily. Officials also point out that Covid was a brand-new virus, while this one is not. Knowledge of the Andes virus is limited, but it has been studied in outbreak settings before.
More cases are expected to be identified, but both the US Centers for Disease Control and Prevention and the World Health Organization say the risk to the general public remains low.
Still, some health experts say that at points, the messaging has been overly confident and too willing to dismiss the possibility of a threat. Statements meant to quell anxiety instead risk undermining trust if they later turn out not to be true.
There’s a difficult balance, too, in trying to keep it simple and ending up too vague.
Late Sunday, after the return of 18 passengers from the cruise ship MV Hondius to the United States, HHS announced that one person had tested “mildly PCR positive” for the Andes strain of hantavirus.
That phrasing launched a barrage of criticism.
“Fortunately, the receiving facility is equipped to handle this. But whoever wrote that someone tested ‘mildly positive’ is an idiot,” wrote Dr. Jeremy Faust, an ER doctor at Brigham and Women’s Hospital in Boston and editor of the doctor-focused news site MedPage Today. “They have it.”
On Monday, the CDC’s Dr. Brendan Jackson explained in a news briefing that the person had two tests before arriving in the United States: one positive, one negative. Follow-up testing will help doctors make a more definitive diagnosis, he said.
Even so, to some, it exemplified the communications problems around the hantavirus outbreak.
“What does ‘mildly PCR positive’ mean? Symptomatic or not? Confirmed or suspected? What testing was done? Clear, precise public health communication matters,” said Dr. Krutika Kuppalli, an infectious disease expert at UT Southwestern Medical Center who has also worked as a medical officer for the World Health Organization, on social media. “This is another example of the leadership void we are seeing and when messaging is vague, misinformation fills the gaps.”
Confident or ‘calm-mongering’?
