Rabies Infection

Updated on August 19, 2016





Rabies is caused by a virus which attacks domestic and wild animals such as dogs, cattle and yellow mongooses.

The rabies virus is transmitted to humans by the bite of an infected animal.


Effects on Humans


* An incubation period of 1-60 days may occur where the person who has been bitten shows no signs and symptoms of rabies.

* Onset of the illness may occur after the incubation period. Symptoms that may occur include headaches, fever, sore throat, nausea, diarrhoea and fatigue. Note that those symptoms do not necessarily mean the person has rabies, since they may occur because of other diseases as well.

* During the acute neurological or agitation phase, the infected person may run about, undergo convulsive seizures, produce large amount of saliva, show a fear of water (hydrophobia) and have difficulty in swallowing and breathing.

* Death may occur 1-10 days from onset of the illness due to heart failure, breathing difficulties or seizures.

People who work in veterinary clinics and animal welfare organisations should be immunized by taking a vaccine against the rabies virus. They should also wear protective clothing, including gloves, when working with animals.
