Can a rat bite cause a tetano?

Yes, a rat bite can potentially lead to tetanus if the bacteria that cause tetanus, Clostridium tetani, enter the body through the wound. While tetanus is more commonly associated with deep puncture wounds, any bite that breaks the skin can pose a risk if the bacteria are present. It's important to clean the wound thoroughly and seek medical attention, especially if you are not up to date on your tetanus vaccinations.
