H10N3 BIRD FLU: A 41-year-old man from east China’s Jiangsu Province has been confirmed as the first human case of infection with a rare strain of avian flu/bird flu called H10N3, the Beijing National Health Commission (NHC) said on Tuesday, June 2, 2021.
Many different strains of bird flu exist in China, and some sporadically infect people, usually those who work with poultry. There is no evidence that H10N3 bird flu can spread easily in humans.
China reports its first world case of H10N3 BIRD FLU
The man, a resident of Zhenjiang City, was hospitalized on April 28 and diagnosed with H10N3 on May 28, the health commission said, which did not provide details about his infection.
His condition is stable now and he can be released. The investigation of his close contacts revealed no further cases, said the NHC. No other cases of human H10N3 infection have been reported worldwide, he added.
H10N3 bird flu symptoms
H10N3 is low-pathogenic, which means it causes relatively less severe disease in poultry and is unlikely to cause a large-scale outbreak, the NHC added.
Symptoms of H10N3
Severe respiratory illness (shortness of breath, difficulty breathing, pneumonia, respiratory failure)
Influenza-like illness (fever, cough, sore throat, muscle aches)
Neurologic changes (altered mental status, seizures)
However, avian influenza viruses cannot be diagnosed based on signs and symptoms alone; The CDC says laboratory tests are needed, usually through swabs taken from an infected person’s upper respiratory tract.
Many different strains of bird flu exist in China, and some sporadically infect people, usually those who work with poultry.
H5N8 is a subtype of the influenza A virus (also known as the bird flu virus). While H5N8 poses a small risk to humans, it is very fatal to wild birds and poultry.
In April, highly pathogenic H5N6 avian influenza was found in wild birds in the city of Shenyang in northeast China.
World Health Organizations words on First H10N3 Bird Flu strain found in China
The World Health Organization (WHO) said in a response to reports in Geneva: “The source of the patient’s exposure to the H10N3 virus is currently unknown and no other cases have been found during emergency surveillance among local populations”. There is currently no evidence of human-to-human transmission.
“As long as avian influenza viruses are circulating in poultry, sporadic avian influenza infection in humans is not surprising, which is a vivid reminder that the risk of pandemic influenza is persistent,” added the WHO.
