“…However, these numbers are still below the ideal and have also been observed in other cities in South and Southeast Brazil, such as São Paulo/SP, Rio de Janeiro/RJ, Curitiba/ PR, and Florianópolis/SC 17,18 that have shown coverage under 80%, according recent studies 19,20 . This study showed that there are some factors related to nonadherence of elderly people to vaccination campaigns that may be linked to the lower observed coverage.…”

“…Systemic reactions such as fever, malaise and myalgia can also occur, usually 6 to 12 hours after vaccination, lasting one to two days. Hypersensitivity reactions, anaphylaxis and neurological manifestations are extremely rare [18][19][20][21] . Based on the exposed, the purpose of this study was to estimate An interview was performed by a trained medical student present at the Health Unit two days a week over 12 months.…”

Introduction:The flu, a condition that can affect the elderly by increasing the risk of serious complications can be prevented through vaccination. Estimate the prevalence of signs and symptoms suggestive of influenza in a group of elderly either vaccinated or unvaccinated against influenza was the objective this study. Methods: This is a cross-sectional study performed in a Brazilian City. A structured questionnaire was employed to identify the presence of signs and symptoms of influenza in individuals aged 60 years or over. For analysis of associations between variables the prevalence ratio (PR) and its 95% confidence interval (95% CI) were used. Results: One hundred ninety-six participants were interviewed, of whom 57.7% were female. The average age was 69.7 years. About 25% of the vaccinated and 20% of the unvaccinated in 2009, and 25% of the vaccinated and 22.5% of the unvaccinated in 2010 reported having the flu. Among the vaccinated and unvaccinated in 2009 and 2010, there was no verified association between vaccination and influenza (PR=1.24; [95% CI: 0.63-2.43] and PR=1.11; [95% CI: 0.59-2.09], respectively). Conclusions: This study suggests that, among the elderly selected, the vaccination coverage for influenza is below the ideal, even with projection of the best indices for 2011 (~ 84%). The data on vaccination and disease protection needs further research; however, the results point to the need for measures to better clarify to this population about the disease, its complications and the benefits of vaccination, in addition to combatting the stigma related to low adherence.

“…Influenza C virus is ubiquitous and usually causes a mild upper respiratory tract illness in children and lower respiratory tract illnesses such as bronchitis and pneumonia in infants and children (1,2). To clarify the epidemiology of acute viral respiratory infections in children in Yamagata, Japan, as a part of the National Epidemiological Surveillance of Infectious Diseases, Japan based on the Infectious Diseases Control Law, we performed virus isolation using HHVM, HHVMRG, and HHVe6MRG microplates, containing HEF, HEp-2, Vero or VeroE6, MDCK, RD-18S, and GMK cell lines as well as the HMV-II cell line, in part, for the isolation of viruses, including influenza virus C (1,3-7).…”

Upper respiratory tract infection (URTI) occurs commonly in both children and adults and is a major cause of mild morbidity. It has a high cost to society, being responsible for absenteeism from school and work and unnecessary medical care, and is occasionally associated with serious sequelae. URTIs are usually caused by several families of virus; these are the rhinovirus, coronavirus, parainfluenza, respiratory syncytial virus (RSV), adenovirus, human metapneumovirus, influenza, enterovirus and the recently discovered bocavirus. This review will mainly focus on the rhinovirus, where significant advances have been made in understanding the epidemiology, natural history and relationship with other pathogens.

Clinical Features of Influenza C Virus Infection in Children

Abstract: Influenza C virus is a significant cause of upper-respiratory-tract illness in children < 6 years old, and the risk of complications with lower-respiratory-tract illness is particularly high in children < 2 years old.
