Filariasis

Filariasis is a parasitic infection caused by tiny, thread-like worms that are transmitted to humans through the bites of infected mosquitoes. When an infected mosquito bites you, it deposits microscopic worm larvae into your bloodstream. These larvae then mature and can live for many years in various parts of your body, most commonly your lymphatic system (which helps manage fluid balance and fight infections), but also under the skin or in body cavities, depending on the specific type of filarial worm. Over time, these adult worms reproduce and can cause a range of health problems. The symptoms you might experience depend on where the worms reside and can include chronic swelling in limbs or genitals (lymphoedema), skin changes, or other issues. For many years, the infection might not show obvious signs, making early detection challenging and allowing the parasites to cause damage unnoticed. Your lab tests are crucial for diagnosing filariasis. They help your doctor identify whether you have these parasites and which specific type is present. This might involve looking for microscopic worm larvae in your blood, especially at certain times of day, or checking for specific antibodies your body produces in response to the infection. Accurate diagnosis is essential to determine the most effective treatment plan and prevent the condition from progressing and causing more severe complications.
