We finally define an incident of vaccine failure when a vaccinated patient is diagnosed with influenza during the same season, at least 30 days after the inoculation.
Moreover, influenza epidemics occur simultaneously at the same latitudes across the globe; this was the case even in times when transportation methods did not allow contact between persons over many degrees of longitude over a period of a few weeks [8].
Australia experienced the pandemic influenza A (H1N1) 2009 outbreak at the same time that seasonal influenza circulation was expected.
There are little data directly comparing confirmed pandemic (H1N1) 2009 with contemporaneous seasonal influenza over the same influenza season (4 – 6 ).
An influenza-tuberculosis co-infection case met criteria for both laboratory-confirmed tuberculosis and influenza during the same admission.
The types/subtypes of dominant strains identified by SARI surveillance was almost always among dominant strains identified by the influenza like illness (ILI) surveillance system and influenza activity in both systems peaked at the same time.
Twenty (36%) patients had at least 1 potential patient or HCW source of influenza infection in the same ward within 5 days before ILI or influenza occurrence.
This includes pneumonia caused by pathogens other than influenza, which may also be causes for heart disease morbidity and at the same time omits influenza outbreaks that do not produce much life-threatening illness.
The purpose of the study was to determine whether women who survived uterine cancer received 4 recommended preventive services (mammography, colorectal cancer screening, influenza immunization, and bone density testing) at the same rates as women with no history of cancer.
At the same time, influenza cases were more likely to have higher temperature and chills and rigors but less likely to present with sore throat, providing supporting evidence to a previous study by Monto and colleagues that one of the most predictive symptoms of influenza is fever [20].
