Cambodia Reports Ten Cases of H5N1 Bird Flu in 2025: Health Implications

PHNOM PENH, Cambodia — The Cambodian Ministry of Health has confirmed ten cases of H5N1 avian influenza so far this year, prompting health officials to launch an extensive investigation into the outbreak. The most recent cases involve a mother and son from Siem Reap province, identified on June 29, 2025, following an earlier report of a 41-year-old woman who tested positive for the virus.

According to Dr. Sophal Chea, Director of the National Institute of Public Health, the two new cases emerged in close proximity to the first patient, indicating a possible cluster of infections. "These individuals had direct contact with infected poultry, which emphasizes the need for public awareness and preventive measures," Dr. Chea stated. All patients are currently in stable condition and receiving treatment with antiviral medication Tamiflu.

The Ministry of Health's announcement highlights the ongoing risk posed by H5N1 in Cambodia, where contact with sick or deceased birds remains a significant concern. Interviews conducted in the affected Lbeuk village revealed that the patients had handled and consumed ill poultry, underscoring the vital importance of food safety and hygiene practices.

In response to the outbreak, national and provincial rapid response teams are actively working to identify sources of infection and mitigate further transmission. Health officials have been distributing Tamiflu to those who may have come into contact with the infected individuals and are conducting health education campaigns in affected areas.

"We are taking every precaution to prevent the spread of H5N1, including monitoring and culling at-risk poultry populations," said Mr. Phan Kim, a spokesperson for the Ministry of Agriculture, Forestry and Fisheries. On June 27, officials from the Siem Reap Provincial Livestock and Animal Health Office executed veterinary measures, culling 45 eggs and 16 chickens in the vicinity of previous outbreaks.

Historically, Cambodia has faced challenges with avian influenza, with previous outbreaks leading to severe health implications. According to a report by the World Health Organization (WHO), H5N1 has a high mortality rate in humans, particularly among those with a history of exposure to infected birds. The WHO emphasizes that while the risk of human-to-human transmission remains low, vigilance is necessary to prevent potential outbreaks.

In light of the current situation, health authorities are urging the public to remain vigilant for symptoms of avian influenza, including fever, cough, and difficulty breathing, particularly among individuals who have had contact with sick poultry. "Anyone exhibiting these symptoms should seek medical attention immediately," noted Dr. Chea.

This outbreak serves as a critical reminder of the ongoing threat posed by zoonotic diseases and the need for robust public health strategies to mitigate risks associated with animal-to-human transmission. As Cambodia continues to address these challenges, collaboration among health authorities, agricultural departments, and communities will be vital in safeguarding public health and preventing future outbreaks.

### Conclusion The emergence of the ten cases of H5N1 bird flu in Cambodia highlights the urgency of addressing zoonotic diseases effectively. Continued public health education, proactive disease monitoring, and immediate action in response to suspected cases will be crucial in ensuring community safety and health in the region. As the investigation unfolds, the Cambodian government remains committed to implementing necessary measures to control the spread of avian influenza and protect public health.
