Rabies fatalities in the United States over the past year: Critical insights
Rabies is a deadly virus that primarily affects the central nervous system, causing inflammation of the brain and spinal cord. This virus, belonging to the Rhabdoviridae family and genus Lyssavirus, has 16 virus species and is primarily transmitted through the saliva of infected animals.
The rabies virus is most commonly transmitted through animal bites, but scratches or direct contact with mucosa can also spread the virus. In the United States, contact with infected bats is the leading cause of human rabies deaths.
If a person is exposed to rabies, seeking immediate medical attention is crucial. The treatment depends on whether the person has ever been vaccinated against rabies. For those who have not, both human rabies immunoglobulin and a rabies vaccine will be given, followed by three more doses of the vaccine. For those who are vaccinated, only two doses of the vaccine will be given, one on the initial day and one three days later.
Sadly, once symptoms of rabies appear, the disease is nearly always fatal. These symptoms can include flu-like symptoms such as fever, headache, and overall body aches, which are typically experienced during the incubation period, a time that may last weeks to months after exposure. As the disease progresses, an infected person may experience increasingly severe symptoms such as confusion, agitation, hallucinations, aggressive behavior, and hydrophobia (fear of water).
To prevent rabies, the Centers for Disease Control and Prevention (CDC) recommends pre-exposure prophylaxis for people at high risk of exposure. These people fall into three categories, each with different follow-up requirements. For instance, people in Risk Category 1 should have their blood checked for antibody titers six months after the second dose, while people in Risk Category 3 can either opt for a one-time antibody titer check between one to three years after the two-dose vaccination or receive a one-time booster.
It's important to note that the rabies vaccine is not recommended as pre-exposure prophylaxis for the general US population. However, those traveling to areas where rabid dogs are a problem, as well as people who may encounter animals through work or leisure activities, are at a higher risk of contracting the rabies virus.
In case of a bat encounter, it's essential to handle the situation carefully. If a bat is found in a room, it should be contained for observation and testing, but not captured if that may result in additional exposure. If a dead bat is found, it should not be touched, thrown away, or allowed other people or pets to touch. Instead, call animal control so that the bat can be tested.
In conclusion, understanding rabies and its transmission is crucial for prevention. By seeking immediate medical attention after potential exposure, following vaccination recommendations, and handling encounters with bats responsibly, we can significantly reduce the risk of contracting this deadly virus.
