Explain reasons.A 38 year-old woman went to a hospital and complained of a non-productive cough and dyspnea which has progressed over two weeks. Based on physical examination, she was pale, diaphoretic and in acute respiratory distress. According to her, she had a sexual contact with his partner for the past weeks.
