PHNOM PENH, 14 November 2013 - The Ministry of Health (MoH) of the Kingdom of Cambodia wishes to advise members of the public that two new human cases of avian influenza have been confirmed for the H5N1 virus. These are the 25th and 26th cases this year and the 46th and 47th people to become infected with the H5N1 virus in Cambodia. Case 25 is from Kampong Speu province and case 26 was from Pailin province. The Kampong Speu case is currently in a critical condition whereas the Pailin case has died. Of the 47 confirmed cases, 35 were children under 14, and 27 of the 47 were female. In addition, only 13 cases out of the 26 cases this year survived.
The 25th case, a 3-year-old boy from Veal Vong village, Sendey commune, Samrong Tang district, Kampong Speu province, was confirmed positive for H5N1 human avian influenza on 9th November 2013 by Institut Pasteur du Cambodge.

Laboratory samples were taken on 8th November and Tamiflu administered the same day.
Investigations in the village by the Ministry of Health's Rapid Response Teams (RRT) and the Ministry of Agriculture, Forestry and Fishery's (MAFF) Animal Health Task Force revealed chickens and ducks had been sick andlor dead for approximately three weeks prior to the boy's onset of illness. The boy helped carry dead chickens for his mother who was preparing a meal from the family. The mother regularly purchased sick and dead chickens from a local poultry farm.
The 26th case, a 29-year-old male from KaunDemrei village, SteungTrang commune, Salakrao district, Pailin province, was confirmed positive for H5N1 human avian influenza by Institut Pasteur du Cambodge on 9th November 2013.

"Avian influenza H5NI remains a serious threat to the health of all Cambodians and more so for children, who seem to be most vulnerable and are at high risk. There have been 26 cases ofH5Nl infection in humans this year. Children often care for domestic poultry by feeding them, cleaning pens and gathering eggs. Children may also have closer contact with poultry as they often treat them as pets and also seem to be most vulnerable and are at high risk because they like to play where poultry are found. I urge parents and guardians to keep children awayfiom sick or deadpoultry andprevent them from playing with chickens and duck. Parents and guardians must also make sure children thoroughly wash their hands with soap and water before eating and after any contact with poultry. Hands may carry the virus that cannot be seen by the naked eye. Soap washes away the virus on hands. If children have fast or difficulty breathing, their parents should seek medical attention at the nearest health facility and attending physicians must be made aware of any exposure to sick or dead poultry, " said H.E. Dr. Mam Bunheng, Minister of Health.
A nationwide public health education campaign using radio has been launched in early October. Also, public health education campaigns are being conducted in Veal Vong village, Sendey commune, Samrong Tong district, Kampong Speu province and KaunDemrei village, SteungTrang commune, Salakrao district, Pailin province, using information,education and communications materials to inform families on how to protect themselves from contracting avian influenza. The government's message is - wash hands often with soap and water, before eating and after coming into contact with pou1try;keep children away from poultry; keep poultry away from living areas; do not eatdead or poultry; and all poultry eaten should be well cooked.
H5N1 influenza is a flu that normally spreads between sick poultry, but it can sometimes spread from poultry to humans. Human H5N1 avian influenza is a very serious disease that requires hospitalization. Although the virus currently does not easily spread among humans, if the virus changes it could easily be spread like seasonal influenza. Hence, early recognition of cases is important.
The Ministry of Health will continue to keep the public informed of developments via the MoH website www.cdcmoh.gov.kh where relevant health education materials can also be downloaded.
