He contacted currently the 53 families concerned "to ensure that the individuals are able to recognize, if applicable, the first symptoms of the disease and remind them of the measures to follow". Two of the French nationals "show symptoms which have led to a levy which diagnostic results are pending", says the press release from the ministry of health. According to the American federal Center for Disease Control and Prevention (CDC), 10,000 people have attended since mid-June the Curry village and are therefore likely to have been in contact with the virus. Six cases of hantavirus pulmonary syndrome have been detected and other potential cases are being monitored. According to the Ministry of Health, the hantavirus is not transmissible by the man. The contamination is done by breathing the virus present in the wood dust or the contaminated soil by the droppings of infected rodents. The average incubation period of the disease is spreading from one to six weeks after the exposure. The symptoms are those of the flu muscle. People with these symptoms should consult their physician quickly indicating to him their stay at the American national park. A green number (0,800,636 636) will be operational from 20H00 for all the people who visit the Curry Village and wishing to "further information", still shows the communiqué. Questioned by AFP, the Samu of Paris has stated that a procedure was put in place to cope with potential contamination. Dr. Michel Nahon, practitioner the hospital sunday Samu was assured that there was no panic. "A lot are phoning by excess, but it is better in the doubt call for nothing rather than do not call", for "well detect possible cases", he adds. If we stayed in the park and there are no symptoms, "nothing is done". If there are any symptoms after stay at the campsite, "ca can be different things, but is considered a person as if possible", explains Dr. Nahon. After medical examination, to confirm especially if one is still in the incubation period, "they are to be oriented toward the hospital" for two things: Possibly, depending on what will say the infectiologues, do an analysis of blood to isolate the virus, and especially "do a preventive treatment of complications, in order to limit the risks vital".
