- Imaging tests, such as MRI or CT scans
Treatment for St. Louis Encephalitis
St. Louis Encephalitis is primarily managed through supportive care to alleviate symptoms and complications.
Supportive Care:
- Patients with St. Louis Encephalitis receive supportive care to manage symptoms such as fever, headache, and muscle aches.
Antiviral Medications:
- In severe cases, antiviral medications like ribavirin may be considered to help reduce the replication of the virus causing St. Louis Encephalitis.
Intravenous Fluids:
- In cases where patients experience dehydration due to fever and reduced intake, intravenous fluids may be administered to maintain adequate hydration and electrolyte balance.
Respiratory Support:
- Patients with severe neurological symptoms may require respiratory support, such as mechanical ventilation, to assist with breathing and oxygenation.
Rehabilitation Therapy:
- After the acute phase of the illness, rehabilitation therapy may be needed to help patients regain lost functions and improve quality of life. This may include physical therapy, occupational therapy, and speech therapy.
- However, the effectiveness of antivirals for this specific virus is limited.
