Question 1

When do hantavirus symptoms appear?

Accepted Answer

Hantavirus symptoms typically appear 1–8 weeks after exposure to infected rodents or their droppings. The incubation period can range from a few days to over a month.

Question 2

What are the early symptoms of hantavirus (HPS)?

Accepted Answer

Early HPS symptoms (days 1–5) include fever, fatigue, and severe muscle aches especially in the thighs, hips, and back. Headache, chills, nausea, and abdominal pain may also occur. These can resemble flu.

Question 3

What happens in the cardiopulmonary phase of HPS?

Accepted Answer

In the cardiopulmonary phase (days 4–10), patients develop cough, shortness of breath, and fluid buildup in the lungs. This can rapidly progress to respiratory failure and requires hospitalisation.

Question 4

When should I seek emergency care for hantavirus?

Accepted Answer

Go to an emergency department immediately if you have shortness of breath, rapid heart rate, low blood pressure, or sudden severe back or abdominal pain after possible rodent exposure.

Question 5

What is HFRS — Hemorrhagic Fever with Renal Syndrome?

Accepted Answer

HFRS is caused by Old World hantaviruses and primarily affects the kidneys. It progresses through febrile, hypotensive, oliguric, diuretic, and convalescent phases, with potential kidney failure and internal bleeding.

Question 6

Do people recover from hantavirus?

Accepted Answer

HPS survivors typically recover fully but may experience fatigue for months. HFRS recovery can take weeks to months after the diuretic phase begins.
