From routine appointments to emergency services, it's important to get the care you need-when you need it. But we understand you may be delaying your health needs over concerns about safety. At Mount Sinai, our doctors, nurses, and staff members are working continuously to ensure your safety so that you don't have to put your health on hold. Our doctors at Mount Sinai Health System’s Division of Pediatric Infectious Diseases are specialists, and are available for consultation, diagnosis, and treatment for a broad range of infectious illnesses that affect infants, children, teens, and young adults. We help children who have both acquired and congenital disorders of the immune system. We will advise you about your child’s immunizations for home and for traveling abroad.
