Swine Influenza
The influence of meteorological and climate conditions in the transmission patterns of swine influenza and its possible seasonality are as yet not adequately understood and are the subject of ongoing research.
The World Meteorological Organization (WMO) works on aspects of weather, climate and health with the World Health Organization (WHO). While there are some indications that influenza epidemics may be associated with weather conditions, non-climatic factors, including virus type, existing levels of immunity in the population and human behaviour are generally considered to be more closely related to epidemics.
