Taiwanese nationals visiting parts of India and Indonesia are advised to be alert for contagious diseases that have been spread locally, the Bureau of Consular Affairs (BOCA) under the Ministry of Foreign Affairs said in a press release Thursday. Cases of chikungunya fever, a disease affecting joints, have increased in the New Delhi area during the past two weeks. These come on top of dengue fever epidemics in India's capital. Meanwhile on the Indonesian resort island of Bali, a rabies epidemic has not been effectively controlled, according to the BOCA. Taiwanese nationals visiting these areas are advised to be careful and check information on the Center for Diseases Control website (www.cdc.gov.tw), the bureau said.
