About:
Yellow fever is a viral disease caused by the yellow fever virus. It is a type of arboviral disease, which means that it is transmitted by mosquitoes. Yellow fever is endemic in tropical regions of Africa and South America. The disease is a type of pitta dosha according to Ayurveda. Without proper treatment, yellow fever can be a life-threatening disease.
Causes:
Yellow fever is caused by the yellow fever virus, which is transmitted by mosquitoes. The virus is found in the blood of infected humans and animals. When a mosquito feeds on the blood of an infected person or animal, it becomes infected with the virus. The mosquito can then transmit the virus to other people or animals it bites.
Symptoms:
The symptoms of yellow fever can range from mild to severe. The incubation period is typically 3-6 days. The initial symptoms of yellow fever include fever, chills, headache, muscle aches, and loss of appetite. These symptoms typically last for 3-4 days and then resolve. However, in some cases, the disease can progress to a severe form.
Severe yellow fever is characterized by a sudden onset of fever, headache, muscle aches, backache, and vomiting. Patients may also develop jaundice (yellowing of the skin and eyes), abdominal pain, and bleeding. Approximately 50% of patients with severe yellow fever will die.
