Hantavirus is a serious viral infection transmitted to humans through rodents, which can lead to severe conditions such as lung or kidney failure if left untreated. Following the outbreak on the MV Hondius ship, this virus has come into the spotlight. Here’s what you need to know, compiled with insights from experts.
How Does Hantavirus Spread?
The primary carriers of the virus are rodents such as mice and rats. Transmission occurs mainly through:
- Airborne (Aerosolization): Inhalation of dust contaminated with rodent urine, feces, or saliva is the most common route. This is especially risky during cleaning in enclosed spaces where dust is disturbed.
- Direct Contact: Touching contaminated surfaces and then touching your mouth, nose, or eyes.
- Bites: Rarely, infection can occur through a bite from an infected rodent.
- Human-to-Human Transmission: Generally, hantavirus does not spread between people. However, some rare types, like the Andes virus, have been reported to transmit through very close contact.
Symptoms and Disease Progression
Hantavirus infection usually follows a two-stage course. Symptoms can appear 1 to 8 weeks after exposure:
Early Stage (Flu-Like):
- High fever and chills
- Severe muscle aches, especially in the back, hips, and legs
- Fatigue, headache, and nausea
Late Stage (Critical Phase):
- Pulmonary Form (HPS): Severe shortness of breath, dry cough, and fluid accumulation in the lungs.
- Renal Form (HFRS): Back pain, decreased urine output, and bleeding disorders.
Treatment and Prevention
Currently, there is no approved vaccine or antiviral treatment that directly eliminates hantavirus. Treatment is primarily supportive in a hospital setting, including respiratory support and fluid balance monitoring.
To protect yourself:
- Prevent rodents from entering your home or workplace.
- Use masks when cleaning areas with rodent presence, and disinfect surfaces using wet cleaning methods (e.g., bleach solutions) to avoid stirring up dust.
- Store food in sealed containers that rodents cannot access.
Why This Is Important
Hantavirus is a serious disease with a global mortality rate ranging from 15% to 50%. Recent cases in enclosed environments highlight the importance of monitoring transmission routes carefully.
