Influenza Vaccination part in March for outbreak alert
Process forward Minsal immunizations, unusual H3N2 virus circulation.
by Gabriela Sandoval P.
During the last months of 2011 and the first weeks of this year, the Public Health Institute (ISP) has confirmed cases of influenza in the country, despite being the summer period and low virus circulation. To this, adds epidemiologic outbreak projection for next winter, which promises more strongly than that recorded in the last two years.
Those reasons are what led the Ministry of Health to advance the program of vaccination against influenza virus, to avoid mass contamination. "In recent weeks we have had cases of epidemiological influenza H3N2 and we are concerned, because this situation is not often observed. Typically have small peak in September and October, but it does not continue. This time, the virus has continued in permanent circulation, "explains the director of the ISP, Maria Teresa Valenzuela.
To cope with the coldest months of the year, the Ministry of Health ordered 3.5 million doses of injection, which will begin to be delivered during the last week of March.
This plan seeks, after receiving the injection, people who are at-risk groups sufficient time to build defenses against the virus.
One concern of the health authority, is that because of the low infections registered in the past two years, the virus is spreading quickly. "We had two years, 2010 and 2011, confident about the behavior of influenza in the population, then many of the people have not had contact with the flu and immunity is lost quite easily. We assume that the absence of an outbreak generated major epidemic, there is a more susceptible population, "said Valenzuela, who added that children be vaccinated under 24 months, pregnant women, aged 65 years and health workers and poultry, among others.
International Alert
In late November, the Pan American Health Organization issued an alert to member countries, after the Centers for Disease Control and Prevention (CDC), Atlanta, United States, report the presence of a new type of influenza detected. This is the tri AH3N2 recombinant virus mixture human, avian and pig, which has particularly affected children. "So far it has proven to be more violent.'s Strong contagion from animal to man, but failed to show even if you have a great facility to spread from person to person," said epidemiologist.
Vaccination in schools
In March also be vaccinated nearly 200,000 children in first grade, whooping cough, diphtheria and tetanus. This is a change in the immunization schedule, which until last year considered the dose in children 2 ? core, the side effects associated with the injection.
The new version of the vaccine, however, reduces the reactions and extends protection to 17 years.
