A83: Mosquito-borne viral encephalitis

Mosquito-borne viral encephalitis is a group of illnesses caused by viruses that mosquitoes can carry and transmit to humans. These conditions are primarily characterized by inflammation of the brain, often triggered by a viral infection. Transmission typically occurs when a mosquito carrying the virus bites a person, introducing the virus into their body. Common symptoms at the onset include fever, headache, and tiredness, which may develop into more serious indications such as confusion, seizures, sensory loss, and consciousness impairment with disease progression. The nervous system, particularly the brain, is chiefly affected in these conditions. The severity and course of these diseases tend to vary, and in some instances, they can lead to chronic complications or be fatal. Please note that the specific conditions within this group, like Japanese encephalitis or West Nile encephalitis, may have their own unique features and severities.
