BACKGROUND
Between 04 Mar 2002 to 21 Mar 2002, 31 cases of pneumonia were admitted at a military hospital in South India. Most of these cases were young recruits. The out break was investigated to ascertain the cause and suggest preventive measures.
METHODS
Detailed epidemiological history was taken from all 31 cases and 100 controls. Case sheets, laboratory reports and chest radiographs were studied. Laboratory investigations included sputum examination by Gram stain and blood cultures on brain heart infusion broth. Cultures grown on liquid media were subcultured on solid media. The regimental centre was visited to note the living and environmental conditions.
RESULTS
Epidemiological investigations revealed overcrowding in the regimental centre. The space per recruit was below recommended standards. 51.6% of recruits who contacted pneumonia were sleeping on double deckers as compared to 21% of healthy controls. Blood culture was positive for Streptococcus pneumoniae in 25.8% of the cases. Chest radiograph showed consolidation typical of lobar pneumonia in 67% of the cases.
CONCLUSION
The outbreak of pneumococcal pneumonia occurred due to overcrowding. Chilly weather conditions and stress were contributing factors.
背景
2002年3月4日至2002年3月21日期间，印度南部一家军队医院收治了31例肺炎患者。这些病例大多是年轻新兵。对此次疫情进行了调查，以确定病因并提出预防措施。
方法
对所有31例病例和100名对照进行了详细的流行病学史调查。研究了病历、实验室报告和胸部X光片。实验室检查包括革兰氏染色痰检和脑心浸液肉汤血培养。在液体培养基上生长的培养物转种到固体培养基上。走访了团部中心，以了解生活和环境状况。
结果
流行病学调查显示团部中心过度拥挤。每名新兵的空间低于推荐标准。患肺炎的新兵中有51.6%睡在双层床上，而健康对照中这一比例为21%。25.8%的病例血培养肺炎链球菌呈阳性。67%的病例胸部X光片显示典型的大叶性肺炎实变。
结论
肺炎球菌肺炎疫情是由于过度拥挤所致。寒冷天气条件和压力是促成因素。
