Histoplasmosis in a child with JRA on low-dose methotrexate.

Wear full sleeve clothes and long dresses to cover the limbs; Use mosquito coils, repellents and electric vapour mats during the daytime; Use mosquito nets—to protect babies, old people and others, who may rest during the day. The effectiveness of such nets can be improved by treating them with permethrin (pyrethroid insecticide). Curtains (cloth or bamboo) can also be treated with insecticide and hung at windows or doorways, to repel or kill mosquitoes. Mosquitoes become infected when they bite people who are sick with chikungunya. Mosquito nets and mosquito coils will effectively prevent mosquitoes from biting sick people.
