If hospitalization for severe chickenpox becomes necessary, you should aim for a major multi-specialty hospital. For a child, the Pediatric Ward is the appropriate place, and for an adult, the Internal Medicine or Infectious Disease Ward. Critically, all reputable hospitals are equipped with specialized Airborne Infection Isolation Rooms (AIIRs), commonly known as negative pressure rooms. These rooms are designed for highly contagious airborne diseases like chickenpox. They continuously pull air into the room and filter it before circulating it back, preventing the virus from escaping into hallways and other patient areas. This ensures your loved one receives the intensive care they need while protecting all other patients and healthcare workers in the facility. When in doubt, calling ahead to the hospital's emergency department can provide confirmation and guidance.
