How Dangerous is the Hantavirus Outbreak?

What exactly is hantavirus, what's the current status of the outbreak, and how are news outlets presenting the story?

The Details: Passengers, including 18 Americans, reportedly evacuated the MV Hondius cruise ship in Spain, after the outbreak's inception in early May. "Eight cases have been reported so far, including three deaths. Five of the 8 cases have been confirmed as hantavirus," the World Health Organization (WHO) stated on Thursday. One of the Americans tested positive, though reportedly asymptomatic, and arrived at Nebraska's Biocontainment Unit on Monday. Others are set to be monitored at the University of Nebraska Medical Center's National Quarantine Unit. The Centers for Disease Control and Prevention (CDC) stated on Friday, "At this time, the overall risk to the American public and travelers remains extremely low," and "Routine travel can continue as normal."

What Exactly Is Hantavirus? "Hantaviruses are a family of viruses which can cause serious illnesses and death," according to the CDC. The Andes virus, the type responsible for the outbreak, comes from contact with rodents and is usually only spread interpersonally through "close contact" with an infected individual. Andes can cause hantavirus pulmonary syndrome (HPS), "a severe and potentially deadly disease that affects the lungs." HPS symptoms typically occur 4 to 42 days after exposure, carrying a 38% fatality risk, though the CDC noted, "Typically, people are only infectious while they have symptoms."

Slants In News Coverage: Outlets on the left often led with skeptic framing of the CDC. Some headlines included the following:

• Axios (Lean Left bias): "Hantavirus response stokes questions about CDC"
• Associated Press (Left): "Experts question CDC's response to cruise ship hantavirus outbreak"
• The Washington Post (Lean Left): "Experts wonder 'Where is the CDC?' as a hantavirus outbreak unfolds on a cruise ship"

One exception was Politico (Lean Left), its headline stating, "US health agencies equipped to handle hantavirus, acting CDC director says." 

Contrastingly, headlines on the right often emphasized the CDC's actions and assurances: 

• Washington Examiner (Lean Right): "CDC sends team to evacuate Americans on hantavirus-plagued ship"
• New York Post (Lean Right): "CDC head assures Americans hantavirus outbreak isn't the new COVID"
• Newsmax (Right): "Former CDC Chief to Newsmax: Officials 'Have a Handle On' Hantavirus"

Other News Coverage: Outlets across the political spectrum covered the CDC's message about a low risk of infection, though The New York Times (Lean Left) said the virus is still "bringing some 'Covid PTSD.'" Outlets in the center generally presented the story analytically, highlighting fact-based updates and descriptions of the virus and its cases. Reuters (Center), for example, focused on plainly answering the question, "What is the hantavirus?"
