The life expectancy in Bahrain is 73 for males and 76 for females. Compared to many countries in the region, the prevalence of AIDS and HIV is relatively low. Malaria and tuberculosis (TB) do not constitute major problems in Bahrain as neither disease is indigenous to the country. As a result, cases of malaria and TB have declined in recent decades with cases of contractions amongst Bahraini nationals becoming rare. The Ministry of Health sponsors regular vaccination campaigns against TB and other diseases such as hepatitis B.
