Context:

The recent passing of Betsy Hackman, wife of actor Gene Hackman, has brought attention to hantavirus, a rare but severe viral infection that can lead to life-threatening respiratory illness and internal bleeding.

What is Hantavirus?

According to the CDC, hantaviruses belong to a family of viruses that can cause:

  • Hantavirus Pulmonary Syndrome (HPS): A severe respiratory illness.
  • Hemorrhagic Fever with Renal Syndrome (HFRS): Causes internal bleeding and kidney failure.

How is Hantavirus Contracted?

  • Carried by Rodents: Common carriers include deer mice, white-footed mice, rice rats, and cotton rats.
  • Transmission to Humans:
    • Inhalation of Aerosolized Droppings: The virus spreads when contaminated dust particles from rodent urine, feces, or saliva are disturbed.
    • Direct Contact: Handling infected rodents or their nests.
    • Rare Cases: Bite from an infected rodent.

Symptoms and Progression

  • Incubation Period: Symptoms appear 1-8 weeks after exposure.
  • Early Symptoms (Flu-like):
    • Fever
    • Muscle aches
    • Fatigue
  • Severe Symptoms:
    • Respiratory Distress: Shortness of breath, chest tightness, and fluid in the lungs.
    • Organ Failure: In HFRS, it can lead to kidney failure and internal bleeding.

High-Risk Groups

The CDC highlights that individuals in rodent-prone areas are at higher risk, including:

  • Farmers, campers, construction workers, and homeowners in rodent-infested areas.
  • Children under five, pregnant women, and immunocompromised individuals should avoid handling pet rodents.

Treatment and Prevention

  • No Specific Cure: There is no antiviral medication for hantavirus.
  • Supportive Care:
    • Oxygen Therapy & Ventilation for severe respiratory cases.
    • Intensive Care Support to manage complications.
  • Prevention Measures:
    • Rodent Control: Seal entry points and eliminate rodent infestations.
    • Proper Sanitation: Avoid sweeping contaminated areas; instead, disinfect with bleach solutions.
    • Protective Gear: Wear gloves and masks when cleaning rodent-prone areas.
