Vigilancia, prevención y control del virus de la influenza en Perú

The importance of surveilling the circulation of the influenza virus and timely vaccination of different populations in Peru was analyzed in three sessions by a group of clinical experts from different specialties. The Peruvian national influenza surveillance system has many selected establishments that have become currently ineffective in terms of a timely report. Most of the samples come from Lima. The viral distribution is inadequately analyzed. The northern and jungle areas of the country have weather and season conditions different to those in Lima and on the southern highlands. This lack of coordination is accentuated by the opportunity of arrival of the influenza vaccine in the country. The Ministry of Health uses a trivalent vaccine but the possibility of a tetravalent vaccine with the two type-B lineages must be analyzed from a cost-benefit standpoint. The appropriateness of vaccinating two times a year, regionally, should be assessed.
