July 27, 2024

A health alert has been recently issued in the United States, after a rodent-borne hantavirus killed four people.

About Hantavirus:

  • Hantaviruses are a family of viruses which can cause serious illnesses and death.
  • The virus can cause severe infections of the lungs (with cough and shortness of breath) or kidneys (with abdominal pain, and sometimes kidney failure).
  • It causes diseases like Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS).
  • Transmission:
    • They are spread mainly by rodents like rats and mice, and are not spread from person-to-person.
    • Transmission of the virus to humans occurs through inhalation of infected rodent urine, droppings, or saliva.
  • Symptoms:
    • Its symptoms can be mild or severe, depending on whether a person's lungs become infected. 
    • The infection starts with sudden fever, headache, muscle aches, and sometimes abdominal symptoms, which may be followed by a cough and shortness of breath or by kidney problems.
    • The infection gets worse quickly. Lung failure can occur and may lead to death.
  • Treatment:
    • There is no specific treatment for hantavirus infection, but early medical care can help if serious disease develops. 
    • More than half of people who have this disease in their lungs die.
