Filariasis is a parasitic disease that is transmitted through the bites of infected mosquitoes. It is not a sexually transmitted disease, and sexual contact with a person who has filariasis is not a direct cause of transmission.
However, it is important to note that filariasis is a communicable disease, which means that it can be transmitted from one person to another through the bites of infected mosquitoes. So if your husband has filariasis, it's important for both of you to take measures to avoid mosquito bites, such as using insect repellent, wearing long sleeves and pants, and sleeping under mosquito nets.
If you live in an area where filariasis is endemic, it's also possible that you could become infected with the parasite through mosquito bites even if your husband does not have the disease.
