ĬOPD is progressive airflow limitation caused by chronic inflammation of the bronchus/bronchioles and lung parenchyma and is symptomized with shortness of breath, wheezing, chest tightness, and chronic cough and sputum production, The leading risk factors for COPD are tobacco smoking and exposure to indoor air pollution, ambient air pollution, and occupational pollutants. It is typically caused by a long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Further asthma is characterized by recurrent episodes of breathlessness, wheezing, chest tightness, cough, and sputum production. Īsthma is a chronic inflammatory disorder of the airways characterized by episodes of reversible breathing problems due to narrowing and obstruction of the bronchus and bronchioles. Both asthma and COPD are the most common and most important chronic respiratory diseases globally. Seasonal variation and pattern in prevalence exist both in asthma and chronic obstructive pulmonary disease as both indicated relatively higher prevalence in winter compared to summer and autumn.įive major respiratory diseases are asthma, chronic obstructive pulmonary disease (COPD), lung cancer, pneumonia, and tuberculosis, and they have contributed to 20% of global mortality. Seasonal distribution indicated that chronic obstructive pulmonary disease was relatively higher in winter (January–February). Out of a total of 740 cases of chronic obstructive pulmonary disease, the highest 405 (54.7%) cases were recorded in February and the lowest 0 in April. Seasonal prevalence/pattern show that asthma relatively more prevailed during winter and early spring (December through March). Overall asthma was highest in March with 1128 (51.8%) cases and was lowest in July with 29 (1.3%) cases. ResultsĪ total of 2179 cases of asthma were recorded including 1609 (73.8%) in 2020 and 570 (26.2%) in 2021, and 740 cases of the chronic obstructive pulmonary disease were also recorded in 2020. The data of the indoor patients for the study period were obtained from the official records maintained in the District Head Quarter teaching hospital Dera Ismail Khan. ![]() ![]() This cross-sectional study was conducted to determine monthly and seasonal patterns of asthma and chronic obstructive pulmonary disease in the study area during 2020–2021. Asthma and chronic obstructive pulmonary disease are the major airway diseases and are increasingly important causes of mortality, morbidity, and disability globally.
