HEALTH ADVISORY: INCREASE IN HAND, FOOT, AND MOUTH DISEASE (HFMD) CASES IN THE CNMI

The Commonwealth Healthcare Corporation (CHCC) is advising the community of an increase in reported cases of Hand, Foot, and Mouth Disease (HFMD) in the Commonwealth of the Northern Mariana Islands (CNMI). In 2026 so far, a total of 14 cases has been identified through CHCC surveillance. HFMD is a common viral illness that most often affects infants and young children, though older children and adults can also become infected.

About HFMD

HFMD is typically caused by coxsackievirus and spreads easily in childcare centers, schools, and households. Symptoms usually appear 3–7 days after exposure. Most individuals recover within 7–10 days without medical treatment. Common symptoms include fever, sore throat, painful mouth sores, rash on the hands and feet (and sometimes the elbows, knees, or buttocks), decreased appetite, and fatigue.

Transmission

HFMD spreads through close personal contact, respiratory droplets from coughing or sneezing, contact with contaminated surfaces, and exposure to stool, particularly during diaper changes. Individuals, especially young children, may continue to spread the virus even after symptoms begin to improve

When to Seek Medical Care

HFMD is generally mild and can be managed at home with rest and adequate fluid intake. However, medical attention should be sought if fever persists for more than three days, signs of dehydration develop (such as dry mouth, lack of tears, or reduced urination), severe headache or stiff neck occurs, or symptoms worsen instead of improving.

Prevention and School Guidance

Good hygiene remains the most effective way to prevent the spread of HFMD. Families and caregivers are encouraged to wash hands frequently with soap and water, routinely disinfect frequently touched surfaces and shared items, and avoid sharing utensils, cups, towels, or toys. Because HFMD is typically mild, children may return to school or childcare once they are feverfree, feel well enough to participate, do not have uncontrolled drooling from mouth sores, and any blisters on the skin have dried up. Parents who are unsure of when their child may return to school are encouraged to consult their healthcare provider.

Important Reminder

There is no specific vaccine or antiviral treatment for HFMD. Prevention through proper hand hygiene and staying home when sick remains the best way to limit transmission within our community. CHCC continues to monitor the situation and will provide updates as needed.
