There is no reported case of yellow fever - an acute viral haemorrhagic disease transmitted by infected mosquitoes - in Cambodia, confirmed the Ministry of Health in a recent joint press release with the World Health Organization.
According to the press release, the "yellow" in the name refers to the jaundice that affects some patients. Up to 50 percent of severely affected persons without treatment will die from yellow. There are an estimated 130,000 cases of yellow fever reported yearly, causing 44,000 deaths worldwide each year, with 90 percent occurring in Africa.
The outbreak of yellow fever have occurred since December 2015. The outbreak was first detected in the province of Luanda, where the capital city of Angola is located, and then spread to other provinces in the country. The health authorities in Angola are implementing a number of control and response activities, and an immunization campaign has been launched. Since the second half of 2015, yellow fever virus circulation has also been reported in Mali and Ghana.
The information from the World Health Organization revealed that three imported cases of yellow fever within the last ten days (Mar. 13 and 19) in China. These cases, all Chinese citizens, contracted the disease while travelling in Angola. None of them were vaccinated against yellow fever prior travelling to Angola.
After exposure, the yellow fever virus incubates in the body for 3 to 6 days. The illness can occur in one or two phases. The first, "acute", phase usually causes fever, muscle pain with prominent backache, headache, shivers, loss of appetite, and nausea or vomiting. Most patients improve and their symptoms disappear after 3 to 4 days. Fifteen percent of patients then enter a second phase which is more toxic and develops jaundice and complains of abdominal pain with vomiting. Bleeding can occur from the mouth, nose, eyes or stomach.
There is no specific treatment for yellow fever, heath care provided aims to reduce symptoms for the comfort of the patient. Vaccination is the most important preventive measure against yellow fever and available at Institut Pasteur in Cambodia; and avoid mosquito bite by eliminating potential mosquito breeding sites such as put Abet in water jars or containers or standing water to destroy larvae, clean house and cut shrub around house, upside down the used cans, used tires, coconut shells, broken bottles, flower pots, wear long pants and long sleeves and use repellent.
