Previously restricted to skirts, sister missionaries from The Church of Jesus Christ of Latter-day Saints are now allowed to wear pants in specific missions to prevent mosquito-borne diseases.

The First Presidency and the Quorum of the Twelve Apostles announced the update on Friday, May 20.

Out of the Church’s 418 missions, 230 have a considerable risk for mosquito-borne diseases, such as Zika, Dengue Fever and Chikungunya.

The new guidelines will only apply when mosquito risk is high, during the wet seasons.

The areas affected are parts of Africa, Asia, the Caribbean, Central America, Europe, Mexico, Pacific, the Philippines and South America, according to the press release from Mormon Newsroom.

The Church has encouraged missionaries to wear insect repellent with a high DEET content and clothing treated with permethrin. With the update of these health and safety guidelines, the Church will now pay for these solutions for missionaries.

“We are encouraging and training our missionary force to implement these preventative measures and would also encourage the general membership to consider these measures for themselves and their families,” said Elder Gregory A. Schwitzer, assistant executive director in the Missionary Department.
