👉 Tehdraviro, also known as viral hemorrhagic fever, is a type of infectious disease caused by a virus that typically affects the brain. It manifests as a sudden onset of symptoms such as fever, headache, numbness or weakness, and severe muscle pain within 24-72 hours after exposure to the virus. The pathogen primarily infects the central nervous system (CNS) and can lead to irreversible damage if not treated promptly.
