No, it is not possible to contract rabies through sex or kissing. Rabies is primarily transmitted through the saliva of an infected animal, typically through a bite or scratch. The virus is present in the nerves and salivary glands of the infected animal and is transmitted to humans when infected saliva enters the body through open wounds or mucous membranes, such as the eyes, nose, or mouth.
Rabies is not transmitted through casual contact or through bodily fluids other than saliva. Therefore, kissing or sexual contact with someone who may have been exposed to a potentially rabid animal would not pose a risk of rabies transmission.
However, if your husband suspects he was bitten or scratched by your dog, it is essential for him to seek medical attention immediately. Rabies is a serious and potentially fatal disease, but it can be prevented with post-exposure prophylaxis (PEP) if administered promptly after a potential exposure. PEP consists of a series of rabies vaccinations and, if needed, rabies immune globulin.
Encourage your husband to consult a healthcare professional or visit a doctor as soon as possible to assess the situation and determine whether he requires rabies PEP based on the specific circumstances of the potential exposure. It is always better to err on the side of caution when it comes to potential rabies exposure.
