China Detects First Human H1N2v Swine Flu Case
China found a rare H1N2v swine flu infection in a child.
Investigators tested people, animals, and environmental samples.
They found influenza A in samples from a deceased pig.
This made the pig a possible source of the infection.
However, scientists could not prove exactly how the virus reached the child.
The child had 30 close contacts.
All of those contacts tested negative and did not develop flu-like symptoms while being watched.
The investigation found no evidence that the virus was spreading continuously between people.
China reported its first detected human case of H1N2v swine flu.
Influenza A was found in samples from a deceased pig.
The pig was considered a plausible infection source, but transmission route was not confirmed.
All 30 of the child’s close contacts tested negative for influenza.
No sustained human-to-human transmission was found during the investigation.
