Barking cough A 9-year-old boy
presented with fever, rash, coryza, and photophobia. Throat cultures
were negative. Over the next 4 days the rash worsened significantly and
the boy developed a dry barking cough and difficulty breathing. He died
11 days after the rash initially appeared. Throat cultures, blood
cultures, and sputum cultures all failed to grow pathogenic bacteria.
PPD was negative and there was neither caseaous necrosis nor granulomas
in his lungs. An image of his lungs is shown below. |
