How long do mouse droppings remain infectious? Generally, you are looking at several days to weeks. If you see signs of rodents in your place, you might wonder about Hantavirus. Is it dangerous? Should you be concerned? Yes, it can be harmful to humans. So, be careful when dealing with anything touched by rodents.

Speaking of how long hantavirus can survive in droppings, it varies depending on certain factors. To address the issue, get in touch with a pest control provider. Keep reading to understand more about how Hantavirus spreads.

What is Hantavirus Infection?

Hantavirus starts in rodents like deer mice. Infected mice usually don’t show any signs of sickness but act as carriers of the virus.

These mice spread the virus through their feces, urine, and saliva. They might use saliva to build nests or chew through things and might urinate when scared.

When the hantavirus passes from a mouse to a human, it can lead to hantavirus pulmonary syndrome (HPS) in the person. Sometimes, the infection may not progress to HPS, causing only mild symptoms. However, if HPS develops, it can severely affect your breathing and, in some cases, even lead to death. Usually, the chance of getting this infection from mouse droppings is high.

According to the Centers for Disease Control and Prevention (CDC), Hantavirus present in dust and droppings can remain infectious for several days to weeks. In ideal conditions, the virus can survive and remain infectious for up to 2 to 3 weeks. However, the virus is sensitive to sunlight and heat, and it will be inactivated by these conditions.

While old droppings may not likely give you hantavirus, you should still be careful. Hantavirus can be caught from feces, droplets, or saliva.

These can be found in mouse nests and areas they visit. If you disturb these materials, you could breathe in the particles and get infected with Hantavirus.

Regarding how long Hantavirus can survive in feces, on average, it lasts between 2 and 4 days, but this depends on the conditions around it. It doesn’t last as long in extreme outdoor conditions. And indoors, how long does hantavirus live in droppings? At room temperature, it can survive for up to 4 days. After a pest control treatment, keep the indoor space vacant for about one week to be safe.

When you see signs of a mouse problem, you may find old mouse droppings on different surfaces, usually in hidden areas. Although it’s rare, people can still get hantavirus from dried droppings. So, it’s important to be careful around mouse droppings.

Hantavirus Diseases: Nephropathia Epidemica (NE) and Hemorrhagic Fever With Renal Syndrome (HFRS)

Symptoms of NE and HFRS come on suddenly and can last for a few days to 3 months before recovery. The symptoms may include rash, achy back, nausea, vomiting, upset stomach, severe headaches, and bleeding.

This infection can lead to death in about 15% of people. If you experience symptoms of this disease, seek medical help.

HPS affects your breathing. While NE and HFRS may seem like a stomach virus at first, HPS feels more like the flu. Sadly, it takes the lives of one-fourth of those affected. Some symptoms of HPS include:

  • Fever
  • Fatigue
  • Headache
  • Body aches
  • Digestive issues like nausea, diarrhea, and upset stomach.

After around a week with HPS, you’ll enter the late stage of the sickness, and you might experience:

  • A persistent cough
  • Difficulty breathing
  • Inability to take a full breath

In the late stage, your lungs fill with fluid, making it hard to breathe. If you suspect HPS due to Hantavirus exposure, it’s crucial to seek guidance from a medical professional to improve your chances of recovery and better your condition.

How to Deal with Hantavirus Infection

If you feel healthy and have a strong immune system, you can treat Hantavirus infection using pain relief and fever treatments. Early-stage symptoms should improve within a week. But if symptoms persist or worsen, seek medical help right away.

If you’ve been in contact with mouse droppings recently and experience symptoms, it’s essential to talk to a doctor. They can advise you on what to watch out for and provide treatment options to keep you healthy.

How long can hantavirus live? Indoors, it can survive for up to four days. Outdoors and in sunlight, it lasts for a shorter period. If there’s an infested area, avoid disturbing it for a week after pest control. According to Pennsylvania Department of Health, the survival of the virus for 2 or 3 days has been shown at normal room temperature.

Can hantavirus be transmitted from person to person?

What are the symptoms of Hantavirus infection?

What happens when humans get a Hantavirus infection? Some people might not have any symptoms or only mild illness. But if the infection becomes severe, it can lead to conditions like HPS, HFRS, or NE, each with different symptoms that affect the body in various ways.
