The United Arab Emirates (UAE) has issued a list of mandatory medical conditions that Kenyans and other foreign nationals must meet before they can secure a work or residence visa in the Gulf nation. Under the UAE's medical fitness requirements, all foreign nationals applying for work or residence permits must test negative for communicable diseases such as HIV and tuberculosis (TB) before they can be granted a visa. All foreign nationals seeking a work or residence visa must first be free of communicable diseases such as HIV and tuberculosis (TB). Those found with active or drug-resistant TB, or lung scars linked to the disease, are issued a one-year conditional residence visa and must undergo treatment in the UAE. Many are attracted by tax-free salaries and employment opportunities in sectors such as domestic work, hospitality, healthcare, construction, retail and aviation.
