First human infection of avian influenza detected in China
First Human Case of Highly Pathogenic H10N3 Influenza in China Sparks Concern
In a shocking development, a 41-year-old man from Jiangsu province in China, has become the first human to be infected with the highly pathogenic H10N3 avian influenza strain. Initial symptoms, including fever and flu-like symptoms, emerged on April 23, but the patient's condition worsened and he was hospitalized on April 28.
Samples from the patient, collected a month later, confirmed the presence of the H10N3 virus. Given the bird-origin of the pathogen and its low human transmissibility, experts believe this virus is unlikely to cause a new pandemic. Fortunately, no similar cases have been detected among individuals who had contact with the infected individual.
The H10N3 virus is primarily found in birds, particularly in wild and domestic populations. Historically, it has been classified as a low-pathogenicity avian influenza virus (LPAIV) but recent research indicates that certain strains may have evolved to the point of airborne transmission among chickens, increasing the risk of human exposure in close proximity to infected flocks.
Clinical symptoms for H10N3 human infections are similar to those of other avian flu viruses, characterised by fever, cough, sore throat, headache, and muscle aches, sometimes accompanied by severe pneumonia. However, the severity and symptoms may vary, and cases of asymptomatic infections can occur.
It is crucial to avoid contact with sick or dead birds to minimise the risk of infection. Enhanced biosecurity measures in poultry farms, use of personal protective equipment like gloves and masks, and education campaigns in at-risk communities can help curb the spread of this virus. Active surveillance of avian influenza in both birds and humans, along with prompt reporting of suspected cases, is essential for early detection and containment.
Key Points about H10N3 Influenza:
- Primary Hosts: Wild and domestic birds
- Transmission Route: Direct or indirect contact with infected birds
- Human-to-Human Transmission: Not reported
- Clinical Presentation: Flu-like symptoms, pneumonia
- Preventive Measures: Biosecurity, PPE, surveillance, public awareness
While H10N3 presents limited spread risk among humans, continued monitoring and research is necessary to understand its potential pandemic threat. The detection of the first human infection in Jiangsu signifies the importance of preparedness regarding emergent zoonotic influenza strains.
- The first human case of the highly pathogenic H10N3 influenza strain was reported in a 41-year-old man from Jiangsu province in China.
- Science and medical-conditions experts suggest that H10N3 is unlikely to cause a new pandemic due to its bird-origin and low human transmissibility.
- The sequencing of the H10N3 virus reveals its presence in birds, particularly in wild and domestic bird populations.
- Health-and-wellness awareness campaigns regarding contact with sick or dead birds are essential to minimize the risk of H10N3 infection.
- CBD, as a preventive measure, is not directly related to the H10N3 influenza, but maintaining overall health and wellness can further strengthen the immune system for potential virus encounters.
