Hand, Foot & Mouth Disease

What is hand, foot, and mouth disease (HFMD)?
Hand, foot, and mouth disease (HFMD) is a common illness of infants and children
caused by a virus. It most often occurs in children under 10 years old. It is
characterized by fever, sores/ulcers in the mouth, and a rash with blisters. The
blisters may appear in the mouth, palms of the hands and soles of the feet. The
rashes may also appear on buttocks and on the legs and arms. The ulcers in the
mouth usually appear on the tongue, the sides of the cheeks, gums or near the
throat.
What causes HFMD?
The most common causes of Hand, Foot and Mouth disease are coxsackie virus
A16, enterovirus 71 (EV71) and other enteroviruses. The enterovirus group
includes polioviruses, coxsackieviruses, echoviruses and other enteroviruses.
When and where does HFMD occur?
Individual cases and outbreaks of HFMD occur worldwide, more frequently in summer
and early autumn (in temperate countries). In the recent past, major outbreaks of
HFMD attributable to enterovirus EV71 have been reported in Malaysia in 1997 and in
Taiwan in 1998. HFMD is endemic in Malaysia and occurs every year. In Sarawak, the
number of cases of HFMD tends to increase from February to June.

Is HFMD serious?
HFMD caused by coxsackie virus A16 infection is a mild disease and nearly all patients
recover within 7 to 10 days. Complications are uncommon. HFMD caused by
Enterovirus EV71 may be associated with neurological complications such as aseptic
meningitis and encephalitis. Cases of fatal encephalitis which occurred during
outbreaks of HFMD in Malaysia in 1997 and in Taiwan in 1998 were caused by EV71.

Is HFMD contagious?
Yes, HFMD is moderately contagious. A person is most contagious during the first

week of the illness. The virus can be transmitted from person to person via direct
contact with nose and throat discharges, saliva, fluid from blisters, or the stool of
infected persons. The virus may continue to be excreted in the stools of infected
persons up till 1 month. HFMD is not transmitted to or from pets or other animals.

How soon will someone become ill after getting infected?
The usual period from infection to onset of symptoms (incubation period) is 3 to 7
days. Fever is often the first symptom of HFMD followed by blister/rash.

What are the clinical signs and symptoms?
HFMD begins with a mild fever, poor appetite, malaise ("feeling sick"), and frequently
a sore throat. One or 2 days after the fever begins, painful sores develop in the
mouth. They begin as small red spots that blister and then often become ulcers. They
are usually located on the tongue, gums, and inside of the cheeks. The skin rash
develops over 1 to 2 days with flat or raised red spots, some with blisters on the
palms of the hand and the soles of the feet. A person with HFMD may have only the
rash or the mouth ulcers.

How is hand, foot and mouth disease diagnosed?
Hand, foot and mouth disease is usually diagnosed based on a complete history and
physical examination of your child. It is generally suspected on the appearance of

blister-like rash on hands, feet and mouth in children with a mild febrile illness.
Usually, the doctor can distinguish between HFMD and other causes of mouth sores
based on the age of the patient, the pattern of symptoms reported by the patient or
parent, and the appearance of the rash and sores on examination. A throat and/or
blister swab collected preferably within 2 days of onset of HFMD may be sent to a
laboratory to determine which enterovirus caused the illness.



2
How is HFMD treated?
Presently, there is no specific effective antiviral drugs and vaccine available for the
treatment of HFMD. Symptomatic treatment is given to provide relief from fever,
aches, or pain from the mouth ulcers. Dehydration is a concern because the mouth
sores may make it difficult and painful for children to eat and drink. Should their
affected children be having fever, the parents are advised to dress their children in
light, thin clothing, to do tepid sponging with water (room temperature) as often as
necessary, and to expose them under the fan. Taking enough liquids is very important
apart from body temperature monitoring.

Who is at risk for HFMD?
HFMD occurs mainly in children under 10 years old, but may also occur in adults too.
Everyone is at risk of infection, but not everyone who is infected becomes ill. Infants,
children, and adolescents are more likely to be susceptible to infection and illness
from these viruses, because they are less likely than adults to have antibodies and be
immune from previous exposures to them. Infection results in immunity to the
specific virus, but a second episode may occur following infection with a different virus
belonging to the enterovirus group.

What are the risks to pregnant women exposed to children with HFMD?

Because enteroviruses, including those causing HFMD, are very common, pregnant
women are frequently exposed to the virus as well. As for any other adults, the risk of
infection is higher for pregnant women who do not have antibodies from earlier
exposures to these viruses, and who are exposed to young children - the primary
spreaders of enteroviruses.

Most enterovirus infections during pregnancy cause mild or no illness in the mother.
Although the available information is limited, currently there is no clear evidence that
maternal enteroviral infection causes adverse outcomes of pregnancy such as
abortion, stillbirth, or congenital defects. However, mothers infected shortly before
delivery may pass the virus to the newborn. Babies born to mothers who have
symptoms of enteroviral illness around the time of delivery are more likely to be
infected. Strict adherence to generally recommended good hygienic practices by the
pregnant woman might help to decrease the risk of infection during pregnancy and
around the time of delivery.
HMFD in childcare facilities
HFMD outbreaks occurring in childcare facilities usually coincide with an increased
number of cases in the community. Additional cases may occur since the virus may be
excreted in the stools of infected person for weeks after the symptoms subsided.

There is no specific recommendation regarding the exclusion of children with HFMD
from childcare programs, schools, or other group settings. If there is an evidence of
transmission in any childcare setting (2 or more cases detected within a period
of 7 days), Sarawak Health Department will close the premise for a period of 14
days.

During an outbreak, everyone is advised:

• To always practise good hand washing technique and good personal hygiene,
• Thoroughly wash and disinfect contaminated items and surfaces using diluted
solution of chlorine-containing bleach (10% concentration).

• Daily examination of children for HFMD; if positive, call parents to bring child
home and don’t bring child back to childcare center till recover.

• Disinfect premises
• Proper handwashing demo to children
Can HFMD be prevented?
Specific prevention for HFMD or other non-polio enterovirus infections is not available,
but the risk of infection can be lowered by good hygienic practices. Preventive
measures include:
a. Frequent hand washing, especially after diaper changes, after using toilet
and before preparing food,
b. Maintain cleanliness of house, child care center, kindergartens or schools
and its surrounding,
c. Cleaning of contaminated surfaces and soiled items with soap and water,
and then disinfecting them with diluted solution of chlorine-containing
bleach (10% concentration),
d. Parents are advised not to bring young children to crowded public places
such as shopping centers, cinemas, swimming pools, markets or bus
stations,
e. Bring children to the nearest clinic if they show signs and symptoms.
Refrain from sending them to child care centers, kindergartens or schools.
f. Avoidance of close contact (kissing, hugging, sharing utensils, etc.) with
children having HFMD illness to reduce of the risk of infection.

HFMD In Sarawak

Hand-foot-mouth disease (HFMD) is endemic in Sarawak. Prior to 1997, there was no
baseline data on the epidemiology of HFMD in Sarawak. This is due to the fact that
HFMD is not a notifiable disease in Malaysia and in Sarawak.

Between 15 April and 30 June 1997, 31 previously healthy infants and young children
in Sarawak died after a short febrile illness against a background of an outbreak of
HFMD in the State. Sibu was badly affected during this outbreak as 11 of the death
cases were reported from Sibu followed by Sarikei with 7 death cases.

Surveillance of HFMD was initiated by Sarawak Health Department during this
outbreak of sudden deaths among young children in Sarawak from 6 June 1997. The
surveillance was stopped in December 1997. However, in 1998, following a report of
increased cases of HFMD seen in private paediatrician clinics, sentinel surveillance of
HFMD in collaboration with UNIMAS was re-started in the State involving urban public
and private clinics in Kuching, Sibu and Miri and 3 government hospitals in Sarawak.
When the enterovirus outbreak was reported in Taiwan in May 1998, the surveillance
of outpatient and inpatient HFMD was extended to all government health facilicities in
the state in June 1998.

Epidemiological data from the sentinel surveillance conducted by Sarawak Health
Department and UNIMAS shows a three yearly EV71 epidemic cycle and predicted the
occurrence in 2006. Hence, a reminder was sent to our division/district health offices
in 2005 to intensify surveillance for HFMD and increase health promotion and
education activities particularly at children care centers and institutions.

In 2006, the surveillance data does not depict any unusual increase in the number of

HFMD cases in the State. However, in Sibu, the cases reported by week are; week 1
(no case), week 2 (3 cases), week 3 (10 cases), week 4 (57 cases), week 5 (54
cases), week 6 (26 cases) and week 7 (24 cases). As of 2 March 2006, there are four
notified HFMD deaths in Sibu Hospital. Out of that, only 2 cases found to be positive
for EV71.
