The most recent, cumulative World Health Organization (WHO) table of human H5N1 cases was published on March 3, 2015.[1] This table notes a total of 88 human H5N1 cases in Egypt through March 3, 2015. As I noted previously [2] the tabulation of counts based on the line list of cases published in the monthly risk summaries only totals 82 cases for Egypt in 2015 based on onset dates in reports of 2015. To understand the confusion in the Egyptian case counts in the WHO table, it is necessary to consider the 2014 totals provided by WHO. The current WHO cumulative table reports 46 cases of H5N1 in 2014 with 31 cases from Egypt.[1] However, individual enumeration of WHO-confirmed H5N1 cases based on line lists in the monthly risk assessments shows a total of 52 H5N1 cases in 2014 (based on onset dates), with 37 of these reported from Egypt.[3] The table below identifies the distribution of WHO-confirmed H5N1 from Egypt by each of the monthly summaries for 2014 through the most recent asse...

In late December 2014, Egypt surpassed Indonesia in the number of reported A(H5N1) cases.[1] As of March 3, 2015, the World Health Organization (WHO) has confirmed a worldwide cumulative total of 784 human H5N1 cases, about 37% or 292 of these cases have been reported from Egypt (Table 1). Eighty-two of those cases from Egypt occurred in the first two months of 2015.[2] In addition, media reports suggests that another four cases have occurred since late February in Egypt and may be included in future monthly updates by WHO.[3]   The recent WHO report from 3 March 2015 notes “ The number of laboratory-confirmed human cases of avian influenza A(H5N1) virus infection in Egypt with onsets of illness in the months of December 2014, January and February 2015 are the highest numbers reported by any country in a single month.” To put these statistics in perspective, about 36% of all H5N1 cases reported from Egypt have occurred in the last 3 months. The graph below shows the distributi...
