Concerns About Rabies and Plague: Should You Worry After a Mouse Encounter? - Family Medicine

Are you concerned about the possibility of rabies and plague infections, or are you overthinking it?


Hello Doctor, I would like to ask you about a situation.
There have been mice in my workplace, and about two weeks ago, while I was eating my lunch, I had to leave suddenly due to an urgent matter and forgot to cover my food.
There was no one else around, and due to the pandemic, I had a single-person partition set up.
I returned about five minutes later to finish my meal and noticed that one of the flavors seemed a bit off.
I’m not sure if I’m overthinking it, but I felt quite anxious afterward because I have a sore in my mouth.
I would like to know if there is a possibility of contracting rabies or plague in this situation.
I have also been feeling cold, nauseous, and have abdominal pain in the past few days.
Thank you, Doctor.

It's understandable to feel anxious after an encounter with mice, especially when considering the potential health risks associated with rodent-borne diseases like rabies and plague. However, let's clarify some important points regarding these concerns.

Firstly, rabies is primarily transmitted through the bite of an infected animal, most commonly bats, dogs, and other mammals. The virus is not typically spread through contact with rodent droppings, urine, or saliva. In fact, rodents such as mice and rats are not known to be significant carriers of rabies. Therefore, unless you were bitten by a mouse or had direct contact with its saliva in a way that could introduce the virus into an open wound, the risk of rabies in your situation is extremely low.

Regarding the plague, it is also important to note that while rodents can carry the bacteria that cause the plague (Yersinia pestis), the disease is primarily transmitted through flea bites or direct contact with infected animals. The symptoms you describe, such as feeling cold, nausea, and abdominal pain, are not typical symptoms of plague. Plague symptoms usually include fever, chills, and swollen lymph nodes (buboes), among other signs. If you have not had direct contact with a sick rodent or flea, the likelihood of contracting the plague is also very low.

Your anxiety about the situation is understandable, especially given the current climate of health concerns. It's common for people to experience heightened anxiety when faced with potential health risks, particularly in a work environment where rodents are present. However, it's essential to differentiate between what is a realistic concern and what may be an exaggerated fear.

If you are experiencing physical symptoms such as abdominal pain, nausea, or feeling cold, it is crucial to consult a healthcare professional. These symptoms could be related to various factors, including stress, anxiety, or even unrelated gastrointestinal issues. A medical professional can provide a thorough evaluation and determine if any treatment is necessary.

In managing your anxiety, consider the following strategies:
1. Educate Yourself: Understanding the actual risks associated with rodent encounters can help alleviate unnecessary fears. Knowledge is a powerful tool in reducing anxiety.

2. Practice Mindfulness: Techniques such as deep breathing, meditation, or yoga can help calm your mind and reduce anxiety levels. These practices can help you focus on the present moment rather than worrying about potential health risks.

3. Limit Exposure to Triggers: If certain environments or situations increase your anxiety, try to limit your exposure to them when possible. For example, if you know that seeing mice causes you distress, take steps to avoid those areas or discuss pest control measures with your workplace.

4. Seek Professional Help: If your anxiety continues to interfere with your daily life, consider speaking with a mental health professional. Therapy can provide you with coping strategies and help you address the underlying causes of your anxiety.

5. Stay Informed but Not Overwhelmed: While it's important to stay informed about health risks, avoid excessive research that may lead to more anxiety. Set boundaries on how much time you spend reading about health concerns.

In conclusion, while your concerns about rabies and plague are understandable, the actual risk from your encounter with a mouse is very low. Focus on managing your anxiety through education, mindfulness, and seeking professional help if needed. Remember, it's okay to seek support when dealing with overwhelming feelings.
