UNIVERSITY PARK, Pa. — University Health Services at Penn State has confirmed three cases of varicella (chickenpox) on the University Park campus. Individuals who have received two doses of the varicella vaccine or have had the disease are considered protected. Those unsure of their immunity should check their records.
Chickenpox, caused by the varicella zoster virus, is a highly contagious disease characterized by itchy blisters that cover the head and body. Symptoms often include a rash that spreads from the head to the rest of the body, along with fatigue, headache and fever lasting several days. In rare cases, chickenpox can lead to serious complications such as infected blisters, pneumonia, bleeding disorders and brain swelling.
The illness spreads through airborne particles and direct contact with an infected person. Symptoms typically develop within 10 to 21 days after exposure. Individuals are contagious one to two days before the rash appears and remain contagious until all blisters have dried. Given the approaching University spring break, individuals should be especially mindful of potential exposure and symptoms.
The risk of infection is low for individuals who have received both doses of the vaccine and breakthrough cases tend to present with milder symptoms, including fewer blisters and little or no fever. Those who have previously had chickenpox are generally immune and reinfection is extremely rare.
University Health Services has identified the origin of the cases at University Park and is working to notify close contacts to help limit the spread. Students and staff who were in Mifflin Hall between Feb. 17 and Feb. 24 or in the Thomas Building on Feb. 20 between 1 and 3 p.m. may have been exposed. Individuals should check their immunization records and, if necessary, schedule a vaccination through myUHS, a local pharmacy or their health care provider.
Anyone displaying symptoms of chickenpox should isolate immediately and contact University Health Services at 814-865-4UHS (4847) or their local health care provider. Those who believe they may have been exposed should also contact a health professional to discuss next steps. A varicella vaccination within three to five days of exposure can help reduce symptoms.
University Health Services encourages all students, faculty and staff to take the following precautions:
- Confirm that you have received two doses of the varicella vaccine. If you have not had chickenpox, consider getting vaccinated.
- Avoid contact with individuals who are ill or have a blister-like rash.
- Wash hands frequently and thoroughly.
Students who are unsure whether they need medical attention can call the UHS 24/7 advice nurse line at 814-865-4847 and press option 3. Appointments can be scheduled via myUHS or by calling 814-865-4847. For more information on varicella, visit the Centers for Disease Control and Prevention website.
