South Africa: Rift Valley Fever

Situation update
There is currently an ongoing outbreak of Rift Valley Fever (RVF) in Free State, Eastern Cape, Northern Cape, Western Cape, and North West Provinces of South Africa. The RVF is spreading rapidly in the Eastern Cape, and there are now 45 farms in the province which have tested positive for the fever.
As of 19 May 2010, the Department of Health of South Africa has reported that there were almost 200 confirmed human cases in the country. The majority of human infections result from direct or indirect contact with the blood or tissues of infected animals. There is some evidence that humans may become infected by ingesting the unpasteurized or uncooked milk of infected animals. Human infections can also result from the bites of infected mosquitoes.

Mainland (Qinghai): Earthquake

More than 2,000 people were killed in the devastating earthquake that hit Yushu County, Yushu Tibetan Autonomous Prefecture in Qinghai Province, on April 14. Qinghai is located in the northeastern part of the Tibetan Plateau with an average elevation of over 3 000 meters above sea level, and the affected Yushu County is at an altitude of 3 600 to 4 300 meters. Travellers visiting Qinghai should beware of the environmental health risks, including High Altitude Syndrome and Extreme Weather Conditions.  Travellers are also at risk of contracting infectious diseases, such as zoonotic diseases (e.g. Plague and Rabies), and food & water borne diseases (e.g. Traveller's Diarrhoea). Therefore travellers should always practice good personal and food hygiene, use repellent against fleas, and stay away from wild and stray animals. Road traffic and personal safety should also be observed.
