Austria's Health Ministry on Wednesday confirmed the country's first case of swine flu after completing virological tests, Austrian daily die Presse said on Wednesday.

The 28-year-old woman, now in quarantine in a Vienna hospital, visited her parents in Guatemala and traveled from Mexico City over Miami and Dusseldorf to Vienna. She went directly from the airport to the hospital on Monday night with flu symptoms. A genetic test showed positive for the H1N1 flu virus. She is from the beginning treated against swine flu virus and is recovering well.

The Vienna state health authority has examined all the persons who had contact with the infected woman during the flight and after her arrival but found no evidence of contagion. However, another infection can not be totally excluded.

Tests on four other suspected patients in Austrian States Vienna and Upper Austria, who have also come back from Mexico recently, have turned out negative.

However, two new suspected cases in Austrian States Vorarlberg and Vienna are still under investigation, and final results will be available on Thursday. Both of the suspected patients have recently returned from Mexico, among which the initial test of a man proved negative.

Expert estimates that approximately 170 persons traveling from Austria to Mexico through travel agencies are still staying in Mexico, who will be examined when they return and will be contacted even on the plane. The number of private travelers is not yet available.
