Santiago, Chile, Jan 8 (EFE) .- The influenza A virus infected two times the same patient, as evidenced by the Clinical Center at the Catholic University of Chile, where there have been three cases of this nature.
A teenager of 14 years, a woman of 62 and a man of 38 who had contracted the disease were infected again, according to experts Carlos Pérez, Marcela Flores and Jaime Labarca.
In three episodes, patients received antiviral treatment, after exposure for the first time and recovered completely, but later returned to the virus, which was confirmed by tests of PCR (polymerase chain), a technique advanced molecular biology.
For the teenager, she contracted the disease 20 days after being discharged, since the woman felt the symptoms in the past 14 days and the man 18 days later.
Cases were reported to the Center for Disease Control and Prevention (CDC, its acronym in English) of the United States, which decided to include them in the first 2010 edition of the journal Emerging Infectius Diseases.
Speaking to the newspaper La Nación, Dr. Carlos Perez, the one responsible for research, said that cases of re-infection by influenza at any of its variants, are rare, so this episode will serve to doctors not rule out a relapse in people infected with H1N1.
This serves as a warning yet about the importance of people who have contracted the disease being vaccinated, because they have ensured his immunity, he added.
According to Perez, these were the first cases of influenza reported recontágio the world and so far no one knows the cause of the patients having contracted the disease twice.
Member of committee of experts convened by the Ministry of Health to address the pandemic in the past year, Perez said the likelihood of a pandemic in 2010 "did not behave with the same intensity," recorded last year.
Health authorities have 3 million doses of vaccine that will be applied free from March in risk groups in Chile.
According to the latest official figures released by the Ministry of Health by 15 December, there were 367,946 reported cases of influenza A in Chile in 2009, of which 12,287 have been confirmed and 1618 were severe, causing 150 deaths. EFE ns / dm
