A study of correlation between the environmental factors and occurrence of Influenza an H1N1cases in Baroda district
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2015, Vol 3, Issue 6
Abstract
The Influenza a H1N1 in humans can be a mild illness or in some people it may result in serious, even life-threatening complications such as pneumonia, acute bronchitis, worsening of chronic conditions, respiratory failure. The objective of this Study is to synthesize the results of these studies in an effort to increase the transparency of what is currently known about the effects of weather and climate on influenza. All the patients admitted in the swine flu isolation ward of both Government and Private Hospital of Baroda District was included in this study. This study includes only confirmed H1N1 virus infected patients in Category “C” admitted in “Isolation Ward” during the period of January to June, 2013 as well as secondary data from records. Correlation of environmental factors in Baroda district in year 2010 shown there was negative correlation between the monthly maximum temperature and occurrence of Influenza a H1N1 cases. (p=0.0087 r= -0.922) Similarly there was negative correlation between the monthly minimum temperature and occurrence of Influenza a H1N1 cases in year 2010 (p=0.0104 r=-0.9157). Monthly maximum and minimum temperature do not have any significant effect on occurrence of Influenza A H1N1 cases in year 2013. (r=0.13, p=0.802; r=-0.25 p=0.622).The atmospheric temperature remains lowest in December, correlating with an increase in the reported number of infected patients with influenza A (H1N1). It continues in January and the winter comes to an end by February; the number of reported positive cases also shows a fall. It signifies the relationship of influenza virus with cold season as maximum number of cases presented during these months of winter season, as reported by other studies. Therefore present study aimed at continued surveillance for detecting Influenza A H1N1 cases is required. Periodic analysis of the data so collected can give us information about the changing epidemiological pattern of the disease or its agent and its correlation with the associated factors.
