Rodent-borne disease issues?


Hello, doctor.
Yesterday, when I was about to leave an internet café, I noticed what seemed to be mouse footprints on the armrest of the chair.
During my time there, my clothes and hands came into contact with the armrest, and I also ordered food to eat because I was hungry.
I didn't specifically clean my hands before eating, as I only discovered the footprints when I was about to leave, so I didn't clean or disinfect in between.
I'm very worried about whether I could contract any diseases from this.

Hello: The information from the Taiwan Centers for Disease Control is as follows: Diseases that can be transmitted by rodents include plague, rat-bite fever, endemic typhus, leptospirosis, scrub typhus, Lyme disease, hantavirus pulmonary syndrome, leptospirosis, and rickettsial spotted fever.
The transmission routes for these infectious diseases include contact (inhalation) with rodent blood, bodily fluids, secretions, tissues, and excreta that carry pathogens, or through bites or ingestion of contaminated food.
Additionally, infection may occur due to bites from fleas, lice, or mites that infest rodents.
However, since you only suspect the presence of rodents and cannot confirm any direct contact, it is recommended that you seek medical attention only if you experience any discomfort.

More Info


When it comes to concerns about mouse-borne diseases after visiting an internet cafe, it's understandable to feel anxious, especially if you noticed mouse footprints on the chair's armrest and had contact with it before eating without proper hand hygiene.
Firstly, it’s important to recognize that mice can carry various pathogens that may lead to diseases transmissible to humans. Some of the notable diseases associated with rodent exposure include hantavirus pulmonary syndrome, leptospirosis, lymphocytic choriomeningitis (LCMV), and salmonellosis, among others. The transmission routes for these diseases typically involve direct contact with mouse droppings, urine, saliva, or through bites. In some cases, diseases can also be transmitted indirectly through contaminated surfaces or food.

In your situation, the primary concern would be whether the mouse had left behind any infectious materials on the armrest that you might have come into contact with. If you touched the armrest and then ate without washing your hands, there is a potential risk of transferring pathogens to your mouth. However, the actual risk of contracting a disease in this manner is relatively low, especially if there were no visible signs of contamination (like droppings or urine) and if the cafe maintains a reasonable level of cleanliness.

If you start to experience symptoms such as fever, muscle aches, fatigue, or gastrointestinal issues in the days following your visit, it would be prudent to consult a healthcare professional. They can assess your symptoms and determine if any testing or treatment is necessary.
In terms of preventive measures, it’s always a good practice to wash your hands thoroughly with soap and water before eating, especially in public places. If you’re concerned about cleanliness in environments like internet cafes, consider carrying hand sanitizer for situations where washing facilities are not readily available.

Moreover, if you frequently visit places where rodent activity is suspected, it might be beneficial to be aware of the signs of rodent infestations and to report any concerns to the establishment's management. They can take appropriate measures to ensure the environment is safe and hygienic for all patrons.

In summary, while the potential for disease transmission exists, the actual risk from your described scenario seems low. Maintaining good hygiene practices and being vigilant about any symptoms will help you manage your concerns effectively. If you have any lingering worries or develop symptoms, don’t hesitate to seek medical advice for peace of mind and appropriate care.
