Two new cases of A(H5N1) have just been announced in Cambodia , meanwhile it seems that Viet Nam is not reporting A(H5N1) cases as required by IHR. In a current article in Emerging Infectious Diseases, researchers report on an asymptomatic subclinical A(H5N1) case from Viet Nam from 2011 . This case was discovered by contact tracing of family members of a 40-year-old man who was apparently infected with A(H5N1) and died. While the article discusses the subclinical case, few details about the 2011 index case-patient are presented in the article nor is there a reference. A review of the World Health Organization (WHO) cumulative table of A(H5N1) cases  shows that Viet Nam did not report any A(H5N1) cases to WHO in 2011. Was the index case-patient ever reported to WHO?
