Rodents May Transmit The Hantavirus To Humans

Warning: Rodents May Transmit The Hantavirus To Humans


HPS is deadly respiratory disease that’s transmitted through rodents.

Hantavirus Pulmonary Syndrome (HPS) is a potentially fatal disease that’s transmitted by rats, mice and other rodents. It’s characterized by flu-like symptoms that begin to manifest between 1-5 weeks after infection. Because it’s spread through the feces and urine of infected rodents, homeowners need to take the necessary precaution to exterminate and prevent rodents from accessing their home.

According to the U.S. Centers For Disease Control and Prevention (CDC), HPS has a mortality rate of roughly 38%, making it an incredibly dangerous disease. Some people assume rodent infestations are merely a nuissance, but this disease reveals the potentially life-threatening complications that may arise when sharing a home with rodents. The symptoms of HPS are mild at first and then progress into more serious issues, such as fluid buildup in the lungs.

Symptoms of HPS:

  • Fever
  • Headaches
  • Muscle aches
  • Body aches
  • Dizziness
  • Coughing
  • Chills
  • Lethargy
  • Tightness in chest
  • Trouble breathing
  • Fluid buildup in chest

What Causes The Hantivirus?

The hantavirus is transmitted to humans through the feces and urine of infected rodents. When a person touches the urine or feces of an infected rodent — and then touches their face or mouth — they may catch the disease. In addition, HPS is also transmitted through the air, meaning a person catch the disease simply by breathing in the air around an infected rodent’s urine or feces. The CDC  states the following on their website:

“Rodent infestation in and around the home remains the primary risk for hantavirus exposure. Even healthy individuals are at risk for HPS infection if exposed to the virus.

Is HPS Transmittable Between Humans?

To date, there have been no known cases of HPS being transmitted from one person to another. A study was recently performed to determine whether or not HPS was transmittable between humans. During the study, researchers analyzed the data of healthcare workers who were given the task of caring for people with HPS. Researchers noted that none of the healthcare workers had caught the disease, leaving them to believe that it is not transmittable between humans.

Unfortunately, there’s no cure for HPS, as doctors can only treat the symptoms caused by the disease.

How To Protect Yourself and Your Family Against HPS

Being that the disease is transmitted through rodents, the most important precaution you can take to protect yourself, and your family, against HPS is to keep rodents out of your home.

Rat Nests 101: Identifying The Source of Your Pest Problem


Rat photo by IRRI Photos.

Rat infestations in the home can lead to both physical and mental anguish. These resilient rodents are able to gain entry into the home through cracks and holes no larger than the size of a nickel. Once inside, they’ll spread bacteria and other potentially dangerous microorganisms through their urine and feces, which can lead to a wide range of illnesses.

But the real problem associated with rat infestations is the enormous amount of stress and anxiety they place on family members. No one wants to share their home with rats, and knowing that they are hidden somewhere in in the home is enough to drive family members crazy.

Rats are habitual creatures that typically follow the same routine on a daily basis (or nightly basis — rats are nocturnal). Once they’ve located a source of food, they will likely continue to go back and feed until the source is depleted. If you’re struggling with a rat infestation in your home, you should place all of your food in sealed plastic containers to discourage rats from feeding on it.

Also, it’s recommended that all dog, cat, bird or other pet food is placed in a large metal container with a secure lid. Rats and other rodents love to feast on pet food, and they may even drag some of it to their nesting area.

Contrary to what some people may believe, rats typically don’t nest directly on their food source. Instead, they prefer to build nests in dark, isolated areas where they are protected against natural predators. Unfortunately, attics offer the perfect nesting environment for rats, mice and other rodents. Rats will remain in the attic during the day and come down below to feed on leftover scraps and food in the kitchen and trash.

A rat nest is fairly easy to identify in the attic — assuming it’s in a visible area and not hidden behind a wall. It may consist of shredded insulation, newspaper, cardboard, pine straw and various other materials. Of course, you’ll likely see plenty of droppings covering it as well. Rat nests must be eliminated to discourage them from residing inside the home. Allowing these rodents to build and maintain nests will allow increase the chance of them breeding, which can drastically intensify the problem of an infestation.

What Are The Health Risks of Rats Living Inside My Attic?

rat-paw-01Unfortunately, this is an all-too-common questions among homeowners. Rats are perceived as dirty pests that can chew their way through just about anything, including steel, but how much of a problem do they really pose to families?

Lack of Sleep and Stress

Let’s first talk about the obvious effects of having rats living inside your attic: lack of sleep and emotional stress. Rats, like most rodents, are nocturnal, meaning they actively search for food under the cloak of night. When you lay down in bed after a long and exhausting day at work, you might hear the scampering of rat feet running throughout the attic. Rather than catching some much-needed sleep, you lie in bed staring at the alarm clock for hours on end.

There’s also a very real emotional stress that comes along with rat infestations in the attic. Even if you rarely see them, just knowing that you are sharing your home with these dirty rodents creates emotional stress.

Disease and Illness

Of course, rat infestations may also leave your family susceptible to disease and illness. Rats were responsible for transmitting the Bubonic Plague, which killed millions of Europeans, so don’t underestimate their potential. Some of the diseases and illnesses modern-day rats are known to carry include the following:

  • Murine typhus
  • Leptospirosis
  • Rat-bite fever
  • Hantavirus
  • Jaundice
  • Salmonella
  • Tulameria

Rats typically transmit diseases through urine and droppings. When the sun goes down and family members go their bedrooms to sleep, rats will make their way down from the attic and into the kitchen where they scavenge for any available food. As they tear into your bread, cookie mix, muffin mix and other food products, they leave behind small piles of feces along with pools of urine.

Note: it’s recommended that homeowners dealing with rat infestations place their food in sealed containers until the problem is resolved. This will help protect against transmitted disease while restricting rats of their food source. The plastic wrap of a typical loaf of bread isn’t enough to keep rats at bay. Instead, you need to place the bread in a long plastic container that’s fully sealed.


You might be surprised to learn that rat infestations in the attic pose a serious fire risk. This is due to their ability and natural instinct to chew through anything in their way. Whether it’s cardboard, styrofoam, wood or even electrical wires, rats use their razor-sharp teeth to chew through just about anything. If a rat happens to chew critical electrical wires, it may create a fire.
