Conditions related to a severe headache
Dengue
Dengue is a viral infection transmitted by mosquitoes. It is primarily found in tropical and subtropical regions around the world. Common symptoms include high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. If you experience these symptoms, especially after being in an area where dengue is prevalent, it's important to seek medical assistance. To reduce your risk of dengue, you can take preventive measures such as using mosquito repellent, wearing long sleeves and trousers, and ensuring your living environment is free from standing water where mosquitoes breed.
Japanese encephalitis
Japanese encephalitis is a viral infection that affects the brain and is primarily spread by mosquitoes. Those most at risk include individuals living in or travelling to rural areas of Asia, especially during the rainy season when mosquito populations are high. To reduce the risk of infection, it's important to take preventive measures such as using insect repellent, wearing long-sleeved clothing, and sleeping under mosquito nets. Vaccination is also recommended for people planning to spend extended periods in high-risk areas. Symptoms of Japanese encephalitis can range from mild to severe and may include fever, headache, neck stiffness, and confusion. In more severe cases, it can lead to seizures, paralysis, or even coma. Treatment primarily focuses on supportive care, as there is no specific antiviral treatment for the infection. This may involve hospitalisation for monitoring and managing symptoms. Early intervention is crucial for improving outcomes.
