Concerns Rise Over Hantavirus and Andes Virus Outbreaks
Health officials are currently monitoring a hantavirus outbreak that originated on the MV Hondius cruise ship. This situation has sparked concerns about the Andes virus, a less common strain found in South America.
As of May 11, the outbreak linked to the cruise ship has resulted in about eight cases and three fatalities. The World Health Organization has confirmed that this is the Andes strain of hantavirus.
What makes the Andes virus particularly worrying is its ability to transmit from person to person, unlike most hantaviruses that spread through rodent contact. This raises alarms about the potential for larger outbreaks.
Dr. Marc Siegel, a senior medical analyst, stated, “The Andes strain has been on the rise as rodents migrate north to Buenos Aires in warm, humid conditions. Current studies show no significant mutations in the virus.” The Centers for Disease Control and Prevention (CDC) notes that this virus is mainly found in countries like Argentina, Chile, and parts of southern South America, primarily carried by a species of wild rat.
The Andes strain is known to cause more severe health issues, such as hantavirus pulmonary syndrome (HPS). This rare but serious condition predominantly affects the lungs, leading to fluid buildup that can make breathing difficult. The CDC reports that approximately 38% of individuals with respiratory symptoms may not survive.
Early signs of HPS can include fatigue, fever, and muscle aches. About half of the patients may experience additional symptoms such as headaches, chills, and digestive issues like nausea. Symptoms generally appear within four to 42 days after exposure. It’s important to note that typically only those showing symptoms can spread the virus to others.
While person-to-person transmission of the Andes virus is possible, Dr. Siegel emphasized that it remains relatively rare. He also noted, “There is currently no specific treatment or vaccine available. However, the U.S. Army Medical Research Institute is exploring monoclonal antibodies, and an mRNA vaccine is in development.”
People infected with the virus often receive supportive care to help manage their symptoms, which can include rest and fluids.
Experts explain that the Andes virus doesn’t spread as easily as more contagious illnesses like flu or COVID-19, leading the CDC to assess the overall risk to the American public as “extremely low.”
The CDC recommends that those who think they may have been in contact with an infected person and are experiencing symptoms should reach out to a medical professional or their local health department.
