H5N1 Bird Flu Cases Decline in US as Cambodia Reports New Infection, WHO Maintains Low Risk Assessment
Published 8 months, 2 weeks ago
Description
This is Bird Flu Bulletin: Daily H5N1 Update. Today is Wednesday, July 30, 2025.
Top stories:
First, Cambodia’s health ministry has reported a new H5N1 avian flu case, hospitalizing a man and bringing its national total to 14 human infections this year. This marks a continued trend of sporadic human cases mainly linked to direct poultry exposure. The UN Food and Agriculture Organization, World Health Organization, and World Organization for Animal Health have just published a risk assessment saying the risk to the general population remains low, but is considered low to moderate for those with frequent animal exposure, such as farm workers.
Second, the United States continues to monitor occasional human and animal H5N1 detections. According to the latest Johns Hopkins review, only three human cases have occurred in the US so far this year—down from 67 last year. The reduction in cases has prompted the CDC to shift H5N1 data reporting from weekly to monthly updates. Recent spillovers to dairy cows and rare human infections among dairy and poultry workers have occurred, but there is still no evidence of sustained human-to-human transmission, and the severity of cases has remained mild or moderate.
Third, the WHO reports that since 2003 there have been 986 confirmed human H5N1 infections worldwide, with Cambodia acting as this year’s primary hotspot. The ongoing global spread among wild birds, poultry, and certain mammals means surveillance remains critical. In the last 24 hours, no new countries have reported human cases, and overall risk assessments have not changed for the general public.
Now for a quick comparison with yesterday: There has been one increase in confirmed human H5N1 cases worldwide, following the new Cambodian case. No new case clusters have been identified and no evidence of increased human-to-human spread has emerged.
Turning to new guidance: The World Health Organization has reiterated that the public health risk from H5N1 remains low for most people, but calls for strengthened personal protective measures in occupational settings and continued vigilance, especially as sporadic infections linked to animal contact are likely to persist. The WHO has updated case definitions for H5 reporting and calls for immediate notification of novel influenza cases.
In today’s expert snippet, Dr. Anna Weber, infectious disease epidemiologist at a leading international health institute, shares: “While the drop in human cases this summer is promising, H5N1 remains unpredictable. Spillovers can still occur anywhere where humans and animals mix closely. We need to maintain rapid diagnostics, protect farm and livestock workers, and invest in vaccine development to stay ahead.”
Looking ahead: Tomorrow, health authorities are expected to release updated monthly H5N1 surveillance data for the United States and several countries are due to report regional animal outbreak investigations. Ongoing monitoring will focus on whether recent viral strains show any signs of increasing transmissibility or severity in humans.
