Medical News: Vietnam, like many countries, has been vigilant about monitoring and responding to infectious diseases, especially those transmitted from animals to humans. Recently, the country reported its first-ever case of A/H9N2 avian influenza in a 37-year-old male patient from the southern province of Tien Giang. This development has prompted extensive epidemiological investigations, heightened surveillance measures, and a focus on public health interventions to prevent potential outbreaks.
Medical News: 37-Year-Old Male Infected With H9N2 Avian Flu In Vietnam
Patient Background
The patient, a construction worker residing in Chau Thanh District, Tiền Giang Province, was initially admitted to Military Hospital 120 in My Tho City on March 16. His health deteriorated rapidly, leading to his transfer to HCMC Hospital for Tropical Diseases. Upon admission, he presented with gastrointestinal bleeding, alcoholic liver fibrosis, and sepsis monitoring.
Subsequently, the patient developed pneumonia, requiring intubation and mechanical ventilation due to respiratory distress. Multiple tests, including nasopharyngeal swabs for PCR testing, were conducted to identify the causative agent. It wasn't until April 1 that genetic sequencing confirmed A/H9N2 influenza virus infection.
Epidemiological Investigations and Contact Tracing
Following the confirmation of the A/H9N2 infection, health authorities swiftly initiated epidemiological investigations. Close contacts of the patient, including household members and healthcare workers, were identified and monitored for symptoms. Notably, no secondary infections or clusters have been reported thus far.
The patient's residence was located near a poultry trading area, raising concerns about potential zoonotic transmission. However, there were no reports of sick or dead poultry in the vicinity. This highlights the importance of monitoring high-risk areas where human-animal interactions are prevalent.

Disease Characteristics and Global Context
A/H9N2 avian inf
luenza is a low-virulence virus primarily affecting poultry but capable of infecting humans through close contact with infected animals or their environments. Globally, sporadic cases of A/H9N2 in humans have been documented, emphasizing the need for continued surveillance and preventive measures.
The virus's antigenic characteristics and potential for reassortment with other influenza subtypes underscore the ongoing threat of emerging infectious diseases. Vietnam's experience with A/H9N2 serves as a reminder of the interconnectedness of animal and human health and the importance of interdisciplinary collaboration in disease control.
Preventive Measures and Public Health Guidance
In response to the A/H9N2 case, Vietnamese health authorities have reinforced avian influenza prevention measures. These include:
-Communication and Education: Public awareness campaigns to educate individuals on avian influenza risks and preventive measures.
-Surveillance and Monitoring: Enhanced surveillance of poultry markets, farms, and high-risk areas for early detection of outbreaks.
-Contact Tracing: Thorough contact tracing and monitoring of individuals in close contact with confirmed cases.
-Biosecurity Measures: Strict enforcement of biosecurity protocols in poultry farming and trading to minimize transmission risks.
-Healthcare Preparedness: Training and equipping healthcare workers with necessary protective gear and protocols for managing infectious diseases.
Global Trends and Emerging Challenges
The emergence of A/H9N2 in Vietnam coincides with global trends in avian influenza surveillance. Across regions, there have been reports of avian flu outbreaks in poultry, with sporadic cases in humans. Particularly concerning are instances of transmission to mammals, highlighting the virus's adaptability and potential for interspecies spread.
In the US and Asia, various influenza subtypes, including H5N1, H5N6, H5N8, H3N2, H9N2, and H10N3, have caused outbreaks in both animals and humans. This underscores the dynamic nature of influenza viruses and the continuous threat they pose to public health.
Conclusion
Vietnam's identification of its first human case of A/H9N2 avian influenza underscores the ongoing challenges posed by zoonotic diseases. While the patient's condition remains stable under intensive care, efforts to prevent further spread and mitigate risks continue.
Through robust surveillance, rapid response protocols, and public health education, Vietnam aims to contain the A/H9N2 outbreak and prevent potential pandemics. This case serves as a reminder of the importance of proactive measures, interdisciplinary collaboration, and global solidarity in combating emerging infectious diseases.
