Six Dangerous Diseases Spread by Rats and Rodents

The danger that comes with rodent infestations isn’t just related to hygiene levels and damage to property. Humans can get sick by contracting diseases that mice or rats carry with them. The best thing to do is to avoid them completely and not make physical contact, but if you’re the subject of a rodent infestations – there’s not a lot you can do except getting close to them. See, these diseases are easily transferable if you aren’t careful or if you don’t react quickly enough.

As soon as you start noticing weird sounds from the walls or droppings, you’ll need to start getting rid of them.

This isn’t an article about how to get rid of mice rather, it’s an article that’s meant to educate you on the topic and introduce you to six of the most dangerous diseases that are spread by these rodents.


Typhus causes damage to your respiratory systems and it isn’t a stranger to humans. We’ve been battling this disease for centuries and even now, it is dangerous. Typhus is transmitted through fleas that live on the rats or mice and then jump on humans. Once a flea bites you, there’s a chance it contained Typhus, which can get transferred to you.

Lyme Disease

Lyme Disease is pretty well known due to its frequency in ticks. You can get Lyme Disease if an infected tick attaches itself to you (which can happen if you walk through tall grass). Unfortunately, this isn’t the only method of receiving Lyme Disease. The ticks that have made the rodents their home can walk over to you, thus giving you Lyme Disease.

Symptoms include headaches, skin lesions, and a fever.


A major threat to your health if you’re the subject of a rodent infestation, Hantavirus can be transmitted to you through rat and mice urine. Strains of this disease have been found in rodent feces as well, so if you don’t take care of the problem in time, you’ll have to be extra careful when dealing with the infestation. Use protective clothing!


Salmonella can infect you in various different ways, including raw eggs and meat, and rodent droppings. The thing about rodent droppings is that they’re small; you might not even notice that there are droppings near your food. And if that happens, there’s a pretty high chance that you’ll get infected. Take great care once you start seeing rodents in your home!

Pox (Rickettsia Pox)

House mice are the main culprits behind spreading this disease. You might think that they’re harmless since they’re so small, but mice should be dealt with as soon as possible. Don’t expose yourself to this disease (which isn’t that unknown; there have been over 500 infections during the course of 5 years).

The Plague

One of the most famous diseases that has hit humanity and almost wiped it out, the Plague is around even today. There aren’t a lot of cases on a yearly basis (the average is around 3) and the number of deaths is even smaller. However, there’s no reason you should risk anything and potentially catch the Plague. React quickly!
