Impact of influenza in the post-pandemic phase: Clinical features in hospitalized patients with influenza A (H1N1) pdm09 and H3N2 viruses, during 2013 in Santa Fe, Argentina.

It is important to characterize the clinical and epidemiological pattern of the influenza A (H1N1) pdm09 virus and compare it with influenza A (H3N2) virus, as surveyed in just a few studies, in order to contribute to the implementation and strengthening of influenza control and prevention strategies. The aims in this study were to describe influenza clinical and epidemiological characteristics in hospitalized patients, caused by influenza A (H1N1)pdm09 and influenza A (H3N2) viruses during 2013, in Santa Fe, Argentina. A retrospective study was conducted over 2013 among hospitalized patients with laboratory-confirmed influenza diagnosis.

Single-dose Universal Hepatitis A Immunization in One-year-old Children in Argentina: High Prevalence of Protective Antibodies up to 9 Years After Vaccination.

Background: Single-dose hepatitis A virus (HAV) vaccination was implemented in all Argentinean children 12 months of age in 2005. Previous studies demonstrated high prevalence of protective antibody response 4 years after single-dose vaccination. This study assessed long-term seroprotection against HAV after vaccination.

Cost of Bordetella pertussis illness in tertiary hospitals in Argentina.

Unlabelled: The National Immunization Commission and the National Program for the Control of Vaccine-Preventable Diseases (Programa Nacional de Control de Enfermedades Inmunoprevenibles, ProNaCEI) updated the immunization policy in relation to Bordetella pertussis (BP) in 2009 in order to improve the control of this disease in accordance with international recommendations. To evaluate the financial impact of this new immunization policy, we must first know the cost on the health system of having a hospitalized or outpatient child infected with BP. The objective of this study was to describe the profile of costs of hospitalized or outpatient children with laboratory-confirmed BP infection in three hospitals of Argentina.

Mortality, severe acute respiratory infection, and influenza-like illness associated with influenza A(H1N1)pdm09 in Argentina, 2009.

Introduction: While there is much information about the burden of influenza A(H1N1)pdm09 in North America, little data exist on its burden in South America.

Methods: During April to December 2009, we actively searched for persons with severe acute respiratory infection and influenza-like illness (ILI) in three sentinel cities. A proportion of case-patients provided swabs for influenza testing.

Clinical features of the hospitalized patients with 2009 pandemic influenza A (H1N1) in Santa Fe, Argentina.
