During spring of 2009, a new influenza virus AH1N1 spread in the world causing acute respiratory illness and death, resulting in the first influenza pandemic since 1968. Blood levels of potentially-toxic and essential elements of 40 pneumonia and confirmed AH1N1 were evaluated against two different groups of controls, both not infected with the pandemic strain. Significant concentrations of pot...

We describe three positive influenza AH1N1 cases in a neonatal unit during the influenza pandemic in Spain. One term baby presented with an upper respiratory tract infection, another preterm infant with an apnea episode following nosocomial infection, and thirdly, a term infant of a mother with influenza AH1N1 had severe respiratory distress and pneumothoraces needing high-frequency ventilation.

BACKGROUND In 2009 a new influenza serotype (AH1N1) was identified in Mexico that spread rapidly generating worldwide alarm. San Luis Potosi (SLP) was the third state with more cases reported in that year. The clinical identification of this flu posed a challenge to medical staff. This study aimed at estimating the AH1N1 infection, hospitalization and mortality rates, and at identifying related...

We have described a SIR simulation model for the influenza AH1N1 virus including variable population, periodic transmission coefficient and constant vaccination rate for any age and time. Also, it has been considered the natural mortality rate due to the infection. We analyze the model by means of simulations using several scenarios. The epidemic threshold, that is time and seasonality dependen...

AIM To use the data on the AH1N1 2009 influenza epidemic in the Southern hemisphere countries to predict the course and size of the upcoming influenza epidemic in South-Eastern Europe (SEE) countries and other regions of the World with temperate climate. METHOD We used a comparative epidemiological method to evaluate accessible electronic data on laboratory-confirmed deaths from AH1N1 2009 in...

BACKGROUND Cystic fibrosis is an autosomal recessive disorder characterized by chronic progressive multisystem involvement. AH1N1 virus infections caused classic influenza symptoms in the majority of cystic fibrosis patients while others experienced severe outcomes. CASE PRESENTATION We report a case of late incidental cystic fibrosis diagnosis in a young Caucasian man suffering from respirat...

In 2009 a new strain of the human influenza virus (AH1N1) appeared and reached pandemic levels, initiating an epidemiological alert in Mexico in April of the same year. Its impact was significant because it was a new subtype of the virus, especially for the severity of the symptoms and number of deaths, which required taking security, hygiene and social isolation measures to reduce the risk of ...
