 Influenza at the human-animal interface
 Summary and assessment, 11 May to 24 June 2019

 •New infections1: 
Since the previous update on 10 May 2019, one new human infection with an influenza A(H1N1) variant virus was reported. 

•Risk assessment: 
The overall public health risk from currently known influenza viruses at the human-animal interface (HA)  has not changed, and the likelihood of sustained human-to-human transmission of these viruses remains low.
 Further human infections with viruses of animal origin are expected. 

 •IHR compliance
 All human infections caused by a new influenza subtype are required to be reported under the International Health Regulations (IHR, 2005).2 
This includes any influenza A virus that has demonstrated the capacity to infect a human and its haemagglutinin gene (or protein) is not a mutated form of those, i.e. A(H1)or A(H3), circulating widely in the human population. Information from these notifications is critical to inform risk assessments for influenza at the human-animal interface.


 Avian Influenza Viruses

Current situation:

 Avian influenza A(H5) viruses 
Since the last update on 10 May 2019, no new laboratory-confirmed human cases of influenza A(H5) virus infections were reported to WHO. According to reports received by the World Organisation for Animal Health (OIE), various influenza A(H5) subtypes continue to be detected in birds in Africa, Europe and Asia. Overall, the risk assessment has not changed.

 Avian influenza A(H7N9) viruses 
Since the last update on 10 May2019, no new laboratory-confirmed human cases of influenza A(H7N9) virus infections were reported to WHO. There have been no publicly available reports from animal health authorities in China of influenza A(H7N9) virus detections in animals in recent months.3
 Overall, the risk assessment has not changed
