Lancet-15-year-old boy from Jiangsu H7N9 (Should it be on FT linelist?)

[Biological]

Chinese researchers reported a case of coinfection with H3N2 and H7N9 influenza in a 15-year-old boy from Jiangsu province who was sick in late April and quickly recovered. The team published a case report on their findings in a issue of The Lancet.
Clip:
The previously health student started having symptoms on Apr 25 and went to the hospital the next day when they worsened. Two throat swabs were taken, and rapid testing showed influenza A. Polymerase chain reaction (PCR) testing in Nanjing indicated influenza A, H7, and H3. Virus isolation yielded H7N9 and H3N2 viruses. The H7N9 virus was highly similar to a Zhejiang strain, and the H3N2 virus was closely related to currently circulating seasonal H3N2 viruses, according to the report. The boy was admitted to the hospital where he received osteltamivir (Tamiflu) treatment. He recovered on May 2. Researchers wrote that dual infections are a potential source of reassortment between human and avian viral strains, which could raise the risk of human-to-human transmission.

Should it be on or mentioned on FT linelist? Yes, I believe so!

Do you have a link please? We will certainly include on our list.

Thanks for the catch and quick reference.

Posted on list.

The latest onset date for an officially confirmed A(H7N9) case from Jiangsu Province is April 19th, 2013 (FT case number 118). This teenager experienced symptom onset on April 25th, and even though reported in Lancet, he is not included in the official WHO count.

If this case is classified as an H3N2 case, then China could avoid reporting it to WHO.

Human infection with avian influenza A(H7N9) virus ? update

4 July 2013


The National Health and Family Planning Commission, China notified WHO of an additional retrospectively detected laboratory-confirmed case of human infection with avian influenza A(H7N9) virus.

The patient is a 15-year-old boy reported from Jiangsu who became ill on 25 April 2013 and hospitalized on 26 April 2013. He recovered and was discharged on 2 May 2013. The results of molecular diagnostics were positive for H3N2 seasonal influenza virus and H7N9 avian influenza virus.

On 1 July, Jiangsu Provincial Health Department consulted national and provincial experts for diagnosis.

To date, WHO has been informed of a total of 133 laboratory-confirmed cases, including 43 deaths.

Authorities in affected locations continue to maintain surveillance, epidemiological investigations, close contact tracing, clinical management, laboratory testing and sharing of samples as well as prevention and control measures.

So far, there is no evidence of sustained human-to-human transmission.

Until the source of infection has been identified and controlled, it is expected that there will be further cases of human infection with the virus.

WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions.

WHO continues to work with Member States and international partners to monitor the situation. WHO will provide updates as the situation evolves.
