Vietnem health authorities are reporting a significant increase in hand, foot and mouth disease (HFMD) so far in 2026.
During the first three months of the year, more than 25,000 HFMD cases have been reported nationally, a more than 400 percent increase compared to the same period in 2025 (4900).
In addition, four deaths have been reported this year to date.
More than seven out of 10 cases were reported in the southern region with 18,031 cases.
The majority of HFMD cases occur in children aged 1-5 years (accounting for 92.7%). The number of pediatric patients seeking examination and treatment at healthcare facilities has increased rapidly, with many severe cases.
In particular, laboratory results show the prevalence of enterovirus 71 (EV71), a highly virulent pathogen capable of causing severe neurological complications, rapid progression, and increased risk of death.

HFMD is a common illness that usually causes fever, mouth sores, and skin rash. It can spread quickly at schools and day care centers. Most people get better on their own in 7 to 10 days.
Symptoms may include: fever, sore throat, painful mouth sores that blister and a rash commonly found on the hands and feet. Complications from HFMD are rare.
HFMD is most common in infants and children younger than 5 years old.
HFMD can spread through contact with: Droplets with virus particles made after person sneezes, coughs, or talks; objects and surfaces that have virus particles, fluid from blisters and feces.
HFMD is very contagious. To help prevent catching or spreading HFMD:
Wash your hands often with soap and water for at least 20 seconds, especially after changing diapers, using the toilet, and coughing, sneezing, or blowing your nose.
Help children wash their hands and keep blisters clean.
Avoid touching your face with unwashed hands, especially your eyes, nose, and mouth.
Clean and disinfect frequently touched surfaces and shared items, including toys and doorknobs.
Avoid close contact with an infected person, such as hugging or kissing them.
Suspected and confirmed cases of HFMD must not go to school or work. They must isolate at home for seven to 10 days or until their fever is gone or their wounds are healed.
My husband was in a 15 day coma from this in 2023. I’m convinced that this is spreading more in the US than anyone realizes. We have met several families online, all from the Midwest, who went through a similar story. Sub-typing and reporting to NESS is optional and no one is connecting the dots. Our lives are forever changed and daycares act like it’s “just a rash”.
