Some Infectious and Parasitic Diseases Mortality Periodicities, Seasonality and Trend, by Sex, in Portugal (1980-2012)

Studies have related a multitude of causes of death to seasonal incidence namely on cardio-respiratory diseases and infectious disease. In developed countries, a shift from a summer peak in mortality towards a winter peak has been observed. Also, in tropical countries this has been an important subject for studies. For instance, in Bangladesh a study revealed a relation between sex and seasonal variations in mortality by all causes and in specific causes. According to the authors, the association may find an explanation in the high prevalence of infectious and diarrhoeal diseases.
