Final answer:
Stevens-Johnson Syndrome is a severe skin reaction often triggered by medications or infections. It causes a painful rash, flu-like symptoms, and blisters. 'BAPS H&M' is unrelated to the syndrome.
Step-by-step explanation:
Stevens-Johnson Syndrome is a severe skin reaction often caused by an allergic reaction to a medication or infection. It is characterized by a painful rash that spreads and blisters, accompanied by flu-like symptoms such as fever and sore throat. The syndrome is named after its discoverers, Albert Stevens and Frank Johnson.
The acronym 'BAPS H&M' does not have any relevance to Stevens-Johnson Syndrome. It is possible that this was a typo or an unrelated piece of information.
