India reports its first human avian flu case

In the wake of media reports from India that said the country has detected its first human avian flu case, the health ministry today confirmed that H5 was found in a child who had underlying health conditions and died on Jul 12. The ministry report in Hindi was translated and posted by Avian Flu Diary (AFD), an infectious disease news blog.

The report said the child was first treated in June at the All India Institute of Medical Science (AIIMS) in New Delhi, where the patient’s condition worsened. Tests on respiratory samples were positive for both influenza A and B, and subtyping for influenza A was inconclusive. Follow-up testing at the National Institute of Virology revealed both H5 and influenza B, and genetic sequencing and virus isolation are under way.

Indian media reports, citing officials at AIIMS, said the patient was an 11-year-old boy who died from leukemia complications.

Investigators are following the child’s contacts, including those who work in healthcare, and so far none have shown symptoms. No suspected cases of avian flu in birds have been reported in the area where the child was sick, but enhanced surveillance is taking place.

Global flu activity stays low, dominated by influenza B

In a global flu update covering the last week of June and first week of July, virus levels in both hemispheres stayed at interseasonal levels, with influenza B dominating among the few respiratory samples that have tested positive, the World Health Organization (WHO) said in its latest global flu update.

Sporadic activity was reported from a few countries, including West and East Africa and South Asia, including India, Nepal, and Pakistan. In Southeast Asia, the Philippines reported a few cases.

Of respiratory samples that tested positive for flu at national flu labs, 77.3% were influenza B, with all but two samples belonging to the Victoria lineage. Of subtyped influenza A samples, 58.2% were 2009 H1N1 and 40.8% were H3N2.

The WHO included its usual caveats that flu activity and detection may be influenced by COVID-19 public health measures and changes in surveillance.
