Seroprevalence study in Mexico

[tetano]

City of M?xico. - The inhabitants of the Valle de Mexico resist every time better the influenza A H1N1.

This way it is suggested by the results of a study that the UNAM realized with approximately thousand 400 students of licentiate, of his five campus of the metropolitan zone.

The students donated blood samples in which immune evidences were looked of having contacted the virus.

In 2010, in 40 per cent of them there were antibodies that were demonstrating his contact with the virus and, for 2011, it increased up to 60 per cent.

' It is not easy to extrapolate this information and to say it is the whole Vale of Mexico, but yes it is a very good indicator of that the immunity of the population is growing ', told Malaqu?as L?pez, boss of the Unit of Special Projects of Investigation Sociom?dica of the Faculty of Medicine of the UNAM.

Before the increase of cases and deaths for A H1N1 in the last weeks, also member of the Scientific Committee of Epidemiologic and Sanitary Alertness of the GDF indicated that the virus lives together with the Mexicans, but it already will not provoke catastrophic stages.

The disease that caused a pandemic in 2009, now appears to have ceased to be a serious problem as being a virus that lives with us and much of the population has developed defenses against the virus without having presented it.

To see how the population has assimilated the virus, researchers at the UNAM recruited blood samples of 400 undergraduates and found that 40% of them already had antibodies naturally because they had been in contact with the virus, but not fell, but his body could metabolize for good.

Clearly state that these results are not universal nor give assurance that no one else will get sick, just not as catastrophic scenarios generate again.

Since 2009 we know that many people have come into contact with the virus and have not fallen ill and others do but very slight, since according to the researchers, few cases they feel all the symptoms of full and strong, much less those requiring hospitalization.

"If we connect the three figures, we see that at first contact with the virus was a quarter of a population; later rose to 40% percent and now up to 60%, which gives us an idea of how it will building this base population immunity, "said epidemiologist Malachi Lopez, head of the Special Projects Unit Socio-medical Research, Faculty of Medicine UNAM.

This by the immunity, but also with support from Conacyt are investigating how the virus affects the elderly population, it is still debating whether they are more vulnerable because they are older, or if already have a history and memory immune Long are the toughest. Another part of the study, which included economic resources of Conacyt, is focused on the impact of influenza A H1N1 in adults over 60 years.

For this, blood samples were taken at 300 volunteers. The results are still being analyzed, also advanced that the research findings will be published in scientific journals
