Transcript text: A 36-year-old person enters the hospital in an extremely debilitated condition. They appear to have purple-brown skin lesions apparent on their neck and chest and a persistent cough with a $39^{\circ} \mathrm{C}$ temperature.

Information taken during the personal history reveals the spouse and child are also not feeling well.
