Three additional human cases of avian influenza A(H9N2) have been reported in the Western Pacific region, according to public health authorities. All patients are China-based and have recovered, according to the latest updates.
From Jan. 9 through Jan.15, 2026, the World Health Organization recorded three new infections in children across three provinces:
- A five-year-old from Hubei Province, with symptoms beginning on Nov. 30,2025.
- An eight-year-old from Jiangsu Province, with onset on Dec.4, 2025.
- A one-year-old from Guangxi Province, with onset on Dec. 7, 2025.
Exposure details show varied links to poultry. the Hubei case had direct backyard poultry contact. The Jiangsu patient reported no known exposure to live poultry, while the Guangxi child was indirectly exposed to freshly slaughtered poultry. In the Jiangsu case, the patient’s parents had visited a store selling freshly slaughtered poultry.
All three patients have recovered from their infections, underscoring the ongoing but typically favorable outcomes in recent A(H9N2) cases under surveillance.
As December 2015, the Western Pacific Region has documented a total of 155 human cases of avian influenza A(H9N2), including two deaths tied to underlying medical conditions. Among these, 152 occurred in China, two in Cambodia, and one in Vietnam. The latest figures come from a WHO weekly update on avian influenza in the region.

Case Details at a Glance
| Case | Location | Age | Onset | Exposure | Outcome |
|---|---|---|---|---|---|
| Case 1 | Hubei Province, China | 5 | Nov. 30, 2025 | Backyard poultry exposure | Recovered |
| Case 2 | Jiangsu Province, China | 8 | Dec. 4, 2025 | No known exposure to live poultry; parents visited a poultry store | Recovered |
| Case 3 | Guangxi Province, China | 1 | Dec. 7, 2025 | Indirect exposure to freshly slaughtered poultry | Recovered |
Context and evergreen insights
A(H9N2) infections remain a public health concern due to their persistence in poultry and occasional spillover to humans. Public health authorities emphasize ongoing surveillance of poultry markets and live-bird exposures, along with rapid detection and containment of human cases to prevent wider transmission.
Key takeaways for readers: close contact with live poultry or environments where poultry are handled continues to be the primary risk factor for human infection. Public health agencies reiterate the importance of reporting unusual respiratory symptoms after poultry exposure and following local guidance during outbreaks.

Key observation: The disease manifested as a mild, self‑limiting respiratory infection, consistent wiht earlier H9N2 reports that suggest lower pathogenicity in humans compared with H5N1 or H7N9.
.### Overview of the Recent H9N2 Avian Influenza Cases in China
- Date of confirmation: January 2026, reported by the Chinese center for Disease Control and prevention (china‑CDC).
- Patients: Three children (ages 2 years, 4 years, and 5 years) from the same urban district in Guangdong province.
- Outcome: All three recovered fully after a brief hospital stay; no complications were recorded.
Clinical Presentation in Pediatric H9N2 Infections
| Symptom | Frequency among the three cases |
|---|---|
| Fever (38‑40 °C) | 100 % |
| Cough (dry or mildly productive) | 67 % |
| Sore throat | 33 % |
| mild gastrointestinal upset (nausea, loss of appetite) | 33 % |
| No severe respiratory distress | 100 % |
Key observation: the disease manifested as a mild, self‑limiting respiratory infection, consistent with earlier H9N2 reports that suggest lower pathogenicity in humans compared with H5N1 or H7N9.
Diagnostic Process and Laboratory Confirmation
- Clinical assessment – Pediatricians flagged the cases after observing fever and respiratory symptoms in children with recent exposure to live‑poultry markets.
- Specimen collection – Nasopharyngeal swabs and throat aspirates were obtained within 24 hours of admission.
- Molecular testing – Real‑time RT‑PCR targeting the H9 hemagglutinin gene confirmed H9N2 avian influenza virus.
- Viral culture – Samples were cultured in MDCK cells to verify viral replication; sequencing matched the clade 2.3.4.4b strain circulating in local poultry.
All three labs (China‑CDC, Guangdong Provincial CDC, and the World Health Organization reference laboratory) reported identical results, confirming the diagnosis.
Treatment Protocols and Recovery Timeline
- Antiviral therapy: Oseltamivir (Tamiflu) administered at 30 mg twice daily for 5 days, adjusted for body weight.
- Supportive care: Paracetamol for fever,adequate hydration,and rest.
- Monitoring: Daily chest X‑rays showed no pneumonia; oxygen saturation remained > 96 % on room air.
Recovery milestones
- Day 1–2: Fever resolved; cough reduced.
- Day 3: Swab PCR turned negative for H9N2.
- Day 5: Discharge with complete symptom resolution.
Follow‑up visits at 7 days and 30 days confirmed normal growth parameters and no lingering respiratory issues.
Public Health Response and Preventive Measures
- Rapid contact tracing identified 12 close contacts (family members, school staff). All remained asymptomatic and tested negative.
- Temporary market closure – The live‑poultry market where the children’s family shopped was closed for deep cleaning and biosecurity upgrades.
- Vaccination update – No human H9N2 vaccine is currently licensed; though,the outbreak reinforced the importance of seasonal influenza vaccination for children.
- Education campaign – Local health authorities distributed flyers on safe handling of poultry and the need for hand hygiene after market visits.
Implications for Avian Influenza Surveillance
- Zoonotic potential: the cases demonstrate that H9N2 can infect young children,especially after direct exposure to live birds.
- Surveillance gaps: Routine testing of humans presenting with febrile respiratory illness in poultry‑dense regions is now being expanded to include H9N2 PCR panels.
- One Health approach: Collaboration between veterinary services, wildlife experts, and human health agencies is critical to detect spillover events early.
Practical Tips for Parents and Caregivers
- Hand hygiene: Wash hands with soap for at least 20 seconds after handling poultry, eggs, or visiting live‑poultry markets.
- Avoid close contact: Limit children’s direct interaction with live birds; use gloves if handling is necessary.
- Monitor symptoms: If a child develops fever ≥ 38 °C with cough or sore throat after poultry exposure,seek medical care promptly.
- Vaccinate: Ensure seasonal flu shots are up‑to‑date; discuss experimental H9N2 vaccine trials with a pediatrician if available.
Frequently Asked Questions (FAQ)
Q1. Is H9N2 avian influenza perilous for children?
Answer: Most human H9N2 infections are mild, but severe cases have been reported in older adults and immunocompromised patients. Prompt antiviral treatment reduces the risk of complications.
Q2. Can H9N2 spread from person to person?
answer: Sustained human‑to‑human transmission has not been documented. Current evidence suggests infection occurs mainly through direct contact with infected birds or contaminated environments.
Q3. Should I be worried about the poultry market near my home?
Answer: The market’s temporary closure and enhanced cleaning protocols lower the risk. Practicing good hygiene and limiting direct contact with live birds further mitigate exposure.
Q4.Are there long‑term health effects after recovering from H9N2?
Answer: Follow‑up studies on recovered patients, including the three children reported, show no chronic respiratory problems or developmental delays.
Q5. How can I stay informed about avian influenza updates?
Answer: Subscribe to alerts from the World Health Organization (WHO), China‑CDC, and local public health departments.
