“…It will permit long‐term surveillance of incidence and has facilitated a retrospective study of the effectiveness of a chickenpox vaccine on the incidence of the disease. In the post‐SARS era, study of the cyclical patterns of viral infection 21,22 and the climatic factors that influence virulence will be important to understand how to control and eradicate these diseases. Further investigation and analysis to determine the actual significance of each of the individual risk factors 23 will be needed.…”

The results suggest that season and temperature are significantly related to the incidence of chickenpox. Infectious diseases can be monitored. Prevention procedures can be taken by understanding its pattern and activity in order to decide the best policy for vaccination. Further studies are warranted, particularly for long-term trends, and in other nations with different seasonal temperatures from Taiwan.

“…RSV infected cells bind greater numbers of Neisseria meningitidis and type b Haemophilus influenzae compared with uninfected cells [25]. As RSV infects almost half of all infants by the age of 12 months and is most prevalent in the winter months [26] Table 1. The bacteria were grown on nutrient agar or for some experiments on blood agar to examine the effect of medium on binding to epithelial cells.…”

Factors enhancing adherence of toxigenicStaphylococcus aureusto epithelial cells and their possible role in sudden infant death syndrome

SUMMARYToxigenic strains of Staphylococcus aureus have been suggested to play a role in sudden infant death syndrome (SIDS). In this study we examined two factors that might enhance binding of toxigenic staphylococci to epithelial cells of infants in the age range in which cot deaths are prevalent: expression of the Lewisa antigen and infection with respiratory syncytial virus (RSVT). By flow cytometry we demonstrated that binding of three toxigenic strains of S. aureus to cells from nonsecretors was significantly greater than to cells of secretors. Pre-treatment of epithelial cells with monoclonal anti-Lewisa or anti-type-I precursor significantly reduced bacterial binding (P < 0 01); however, attachment of the bacteria correlated only with the amount of Lewisa antigen detected on the cells (P < 0 01). HEp-2 cells infected with RSV bound significantly more bacteria than uninfected cells. These findings are discussed in context, of factors previously associated with SIDS (mother's smoking, bottle feeding and the prone sleeping position) and a hypothesis proposed to explain some cases of SIDS.

“…Most notably respiratory syncytial virus (RSV) and Bordetella pertussis have a role in causing LRI in these elder patients [7]. Noah found that in England and Wales RSV and parainfluenza 1 and 2 display marked wintertime excess [8]. The most common explanation for the seasonality of respiratory infections is that human congregate indoors in the winter, thus increase the chance for contagion [1].…”

The aim of this study was to analyze the incidence of some respiratory diseases in outpatient´s pneumology departments along three years period and point out seasonal variation in these diseases. The number of examined ambulatory patients suffered from all causes of respiratory diseases and pneumonia on monthly basis were applied to create a timeseries analysis in numerical and graphical output of data. Significant differences in all followed diseases between winter season and summer season were observed. These data are in accordance with data of other authors and epidemiological surveys on long year's basis. Possible reasons of these observations are discussed, and it may speculate about seasonally driven viral circulation. Deficiency in vitamin D levels in wintertime is another possible reason for winter peak in the incidence of respiratory diseases. Our results can aid not only in effective allocation of resources and services but can be helpful for better understanding of respiratory epidemiology, respiratory pathology with potential role of vitamin D in its possible improvement, especially in wintertime.
