The number of people infected with the Influenza A(H1N1) virus in Costa Rica broke the hundred mark this week, although most of the cases are showing light symptoms and swift recoveries, health authorities said.

On Wednesday Health Ministry officials said the number of confirmed cases rose to 104, with 10 more “highly probably” cases still pending confirmation.

A total 114 cases are pending test results for the H1N1 virus.

Nearly 90 percent of the confirmed cases here have been detected in people under 39 years old, 22 of whom are under the age of 10 and another 13 people infected are over 40, according to data released by the Health Ministry.

Both the Blue Valley School, in Escazú, west of San José, and the Saint Anthony School in Tibás, north of the capital, closed after learning of at least three children with H1N1, the daily La Nación reported Wednesday.
