Bolivian Health Minister Ramiro Tapia said that he would get in contact with Argentina's Health Minister to "verify" the magintude of the pandemic. If the disease expands, "the Bolivia-Argentina border will have to be closed for three, four or five days," said Tapia.

"It is concerning, what is happening in Argentina," where the H1N1 virus has already killed 55 people, said Tapia. The Health Minister wants to verify the magnitude of the pandemic's spread.

The first measure is to "double the number of doctors at the border, in that sector, but if we see that there are still cases coming in from Argentina, we will be forced to close down the border," added the Health Minister.

The number of H1N1 cases in Bolivia are still growing and, this weekend, the number of infected persons jumped to 393.

Even though the virus has not yet caused any deaths, three Bolivian citizens are hospitalized and in their conditions are serious. Two are in Santa Cruz, one is in La Paz.
