Case 1 Tuberculosis Case Summary Margaret had been working as a health care worker at an elderly home for three years. Her daily job was to provide personal care service for the residents, such as assisting them in eating and cleaning, tidying beds, giving medicines and cleaning wounds. About three months ago, Margaret began to cough persistently with blood-stained sputum. She also had drastic weight loss and frequent night sweating. She sought treatment at a chest clinic. The X-rays showed opacities in her lungs. Mycobacterium tuberculosis was identified in her sputum. The doctor diagnosed that she had pulmonary tuberculosis. 2
Occupational Disease Casebook - Occupational Infection Causes of the Illness According to the doctor's analysis, Margaret contracted pulmonary tuberculosis for the following reasons: 1 2 3 Three months before the onset of the disease, Margaret was taking care of a resident who had been coughing for weeks. The resident was not given immediate medical treatment as his condition was not serious at the early stage. He was arranged to see a doctor after a few weeks when he coughed up blood. He was diagnosed as having pulmonary tuberculosis and hospitalized. During the resident's stay at the elderly home, droplets containing the bacteria might disperse in the air whenever he coughed and sneezed. As Margaret had not worn a suitable mask when taking care of him, she might have inhaled the infective droplets. Poor ventilation at the elderly home resulted in accumulation of the bacteria in the air. 3
