Filariasis due to Wuchereria bancrofti: Causes, Symptoms and Prevention

Filariasis is a parasitic disease caused by the filarial worm Wuchereria bancrofti. The disease is transmitted to humans through the bites of infected mosquitoes. The infection can cause serious damage to the lymphatic system, leading to lymphedema, hydrocele and elephantiasis.

Symptoms

The symptoms of filariasis may not appear for months or even years after the initial infection. Early symptoms may include fever, chills, headache, and muscle and joint pain. As the infection progresses, individuals may experience swelling of the limbs, genital area or breasts. The skin may become thickened, discolored and scaly, and individuals may develop ulcers and open sores.

Causes

Wuchereria bancrofti is transmitted to humans through the bites of infected mosquitoes. The larvae of the worm enter the human body through the bite wound and migrate to the lymphatic system, where they mature into adult worms. The adult worms can live for several years, and produce millions of microfilariae, which are released into the bloodstream and can be taken up by mosquitoes, completing the transmission cycle.

Prevention

1. Prevent mosquito bites by using insect repellent, wearing long-sleeved shirts and pants, and sleeping under mosquito nets.
2. Reduce mosquito breeding sites by eliminating standing water around homes and communities.
3. Mass drug administration programs can be effective in reducing the number of people infected with filariasis.
4. Improved sanitation and hygiene can also help to reduce the transmission of filariasis.

Conclusion

Filariasis due to Wuchereria bancrofti is a serious parasitic disease that can cause significant morbidity and disability. Prevention efforts, including mosquito control, mass drug administration and improved sanitation, are critical to reducing the burden of filariasis in affected communities.
