The recent viral outbreak which caused death among lives in Cambodia particularly children has been very alarming and should not be taken for granted. The viral infection called EV71 or known as Enterovirus 71 was first recognized in 1974. Over the past years serious outbreaks had been recorded mostly in the Asian countries like China, Taiwan, Malaysia, Hongkong, Vietnam and lately in Cambodia.

The disease is usually affecting children under 7 years old and has been linked to the most severe cases of HFMD (hand, foot and mouth disease), most cases reported had died within 24 hours with exhibited symptoms of fever, respiratory illnesses and widespread neurological abnormalities.

The illness is contagious as its mode of transmission is by direct contact through nose and throat discharges, saliva, fluid from blisters or the stool of infected persons.

  • Persistent high fever
  • Sores in the mouth, rashes with blisters on the hand or foot

  • Good ventilation or aeration
