The WHO report for April 29 shows a small increase in confirmed cases including one death, in Texas, of a toddler from Mexico. In Mexico only 26 deaths from swine flu have been confirmed although it is suspected of killing 154.

WHO's April 30 report shows an increased number of confirmed cases of swine flu. This reflects the increased opportunity for diagnostic lab work, rather than an increased number of infections. In Mexico only 90 cases have been confirmed, with 7 deaths attributed to the disease. This count contradicts the April 29 report from WHO.

     On 2 May 2009 WHO says "15 countries have officially reported 615 cases of influenza A(H1N1) infection. Mexico has reported 397 confirmed human cases of infection, including 16 deaths. The 241 rise in cases from Mexico compared to...1 May reflects ongoing testing of previously collected specimens. The United States Government has reported 141 laboratory confirmed human cases, including one death."
