H5N1 Bird Flu Spreads in Cambodia: 12 Human Cases Reported This Year, Experts Urge Continued Vigilance

This is Bird Flu Bulletin: Daily H5N1 Update for Saturday, July 12, 2025. Top Stories First, Cambodia has confirmed its twelfth human case of H5N1 avian influenza this year. The Ministry of Health announced that a five-year-old boy from Kampot province is currently in intensive care with severe respiratory symptoms. This follows the recent death of a 19-month-old in neighboring Takeo province. Health authorities emphasize that there remains no evidence of human-to-human transmission, but the continued appearance of cases—twelve so far in 2025—has increased concern and international monitoring. According to The Independent, almost half of global H5N1 cases have been fatal since tracking began. Second, in the Americas, the Pan American Health Organization reports that since 2022, 19 countries in the region have experienced 4,948 animal outbreaks of H5N1. As of May, there have been 75 human infections across five countries, with one new case identified since March. These outbreaks have contributed to ongoing monitoring and renewed data sharing across affected regions. Third, the World Health Organization continues to track a global total of 986 confirmed human cases of H5N1 infection as of July 1, 2025, spread across 25 countries. There has been a notable increase: 11 cases in Cambodia alone between January and July this year, including seven cases in June—a monthly spike. Seventeen of the Cambodia cases since 2023 have been in children under 18, with a 44 percent fatality rate among those most recent cases. WHO maintains its assessment that the overall risk to the general population remains low, but occupational exposure, especially among farm workers, carries a low to moderate risk. Changes in Case Numbers Compared to yesterday, there are no new confirmed human cases globally. Cambodia remains at 12 cases for the year, according to the most recent figures from WHO, and the Americas have not reported new cases since the last update in May. The ongoing surge in animal outbreaks, however, keeps public health officials on alert. New Guidance The U.S. Centers for Disease Control and Prevention has streamlined its H5N1 bird flu reporting and now integrates bird flu data with routine influenza surveillance. The CDC continues to stress that, while current risk remains low for the public, it is crucial for those with exposure to sick poultry or wild birds to follow strict hygiene protocols and report respiratory symptoms promptly. The World Health Organization has also updated its confirmed case definitions for H5 infections, aiming for more rapid notification and international response. Expert Interview Dr. Lina Reyes, a veterinary infectious disease specialist, shared her perspective: "The continued reporting of H5N1 cases among children is a signal that surveillance in rural and agricultural settings must remain vigilant. We need to focus resources on community education and rapid response to any sign of illness in both humans and poultry."
