What are the symptoms of rabies in humans after a cat bite? - briefly
Rabies in humans following a cat bite typically manifests with nonspecific initial symptoms such as fever and headache. As the disease progresses, more severe neurological signs appear, including hydrophobia (fear of water), photophobia (sensitivity to light), and paralysis.
What are the symptoms of rabies in humans after a cat bite? - in detail
Rabies is a severe and often fatal viral infection that can be transmitted from animals to humans through bites or scratches, with cats being one of the primary vectors. The clinical manifestations of rabies in humans can be categorized into three stages: prodromal, neurological, and terminal.
The prodromal stage, which typically lasts for 2-3 days, is characterized by non-specific symptoms that may include fever, headache, fatigue, and malaise. These initial signs can often be mistaken for other viral infections, making early diagnosis challenging. As the virus begins to affect the central nervous system, more specific neurological symptoms emerge.
The neurological stage is marked by the development of various abnormal sensations, such as paresthesia or prickling sensations around the wound site. This stage also includes changes in behavior and mood, including agitation, anxiety, and sometimes even hallucinations. The patient may experience difficulty swallowing (dysphagia) due to muscle weakness and spasms of the throat muscles. Hydrophobia, or a fear of water, is another classic symptom associated with rabies. This condition arises from the intense muscular spasms in the throat that occur when attempting to drink water.
As the disease progresses into the terminal stage, severe neurological symptoms become more pronounced. These can include paralysis, seizures, and coma. The patient may exhibit erratic behavior, such as aggression or excessive irritability. Respiratory failure is a common cause of death in rabies cases, often due to paralysis of the respiratory muscles.
It is crucial to note that once clinical symptoms of rabies appear, the disease is almost always fatal. Therefore, preventive measures such as prompt medical attention and post-exposure prophylaxis are essential after a cat bite. If you suspect exposure to rabies, seek immediate medical advice to initiate appropriate treatment and vaccination.
