What is Hantavirus ?

Transmission can occur through :

• Inhaling particles from dried rodent urine or droppings

In the early stage, hantavirus often appears like a common flu:

• Fever
• Muscle pain (especially thighs, hips, back)

At this stage, the condition can progress quickly and requires immediate medical attention.
