[First cases of secondary transmission of a novel swine-origin influenza A (H1N1) virus in France].
On April 2009, a new swine-origin A(H1N1) influenza virus, A(H1N1)v, was identified in the United States. Today (June 12, 2009), more than 29,000 cases have been reported in the world, and 73 in France. This is the first report of secondary transmission in France. The three patients presented with common influenza signs including cough, fever, and sore throat. The incubation period could last from two to four days; it should be kept in mind that the first international data mentioned one to seven days. The buildup and maintenance of an infectious focus involve secondary transmissions.
