Measles is an acute infectious disease of
children, also known as rubeola, caused by
paramyxovirus which is a single stranded
enveloped RNA virus.1 According to WHO, it
remains one of the leading causes of death
among children globally, approximately 158000
people mostly children under the age of five
died from measles in 2011.2 Recently, Pakistan
witnessed measles epidemic particularly in the
province of Sindh from January 2012 to
February 2013, 19,048 suspected measles cases
with 463 deaths of children were reported
throughout the country. Most of these cases
were reported during the last quarter of 2012.3
The total number of cases of measles reported
from Punjab was 19,192 with 239 deaths during
the last six months.4,5 Compared to previous
years these are alarming figures which compels
us as dermatologists to know more about the
disease and its common and uncommon
cutaneous presentations.
The virus resides in the upper respiratory tract of
an infected person. It can spread by droplet
infection or by fomites which are infected by the
secretions. Incubation period of measles is 7-14
days.6
In classical dermatological measles syndrome,
the symptoms are initially nonspecific including

fever, sore throat, cough, rhinorrhea,
conjunctivitis and photophobia.6 During the
initial two to three days the pathognomonic
Koplik’s spots are also seen in the buccal
mucosa.6 The typical maculopapular rash starts
from behind the ears and along the hairline. It
spreads in cephalocaudal pattern to involve the
face, trunk and limbs over the next few days.6
The fever becomes high grade with temperature
rising to 104ºF or 105ºF. The patients remain
infectious from four days before the rash appears
till the four days after the rash is there. The rash
after a few days starts to fade away starting from
the face sometimes leaving behind a staining
pattern or hyperpigmentation.7
There can be an atypical or modified
presentation of the disease. People who received
killed measles vaccine or are exposed to wildtype virus can develop an atypical measles
syndrome.8 The rash can be urticarial, purpuric
or even vesicular. It starts from palms and soles
then spreads to the trunk before fading. Koplik’s
spots in these cases are absent.8 Atypical
measles syndrome may also present with
congested macules and papules starting on the
extremities and back.9 The systemic features
include fever, pleural effusions, pneumonia and
swelling of extremities.9 In HIV positive patients
there can be an atypical rash or no rash at all.9
Skin necrosis or even minute skin coloured
papules can also be seen.9
In modified form of measles the symptoms are
mild and last for a very short time.9 It develops

in those persons who received immunoglobulins
after exposure to measles or the those infants
who were either non-immunized or had low
immunity from their mothers.8
The complications of measles are more common
in children under the age of five, or adults over
the age of twenty. Complications include
diarrhea, otitis media, bronchitis, pneumonia,
corneal ulcerations and scarring, encephalitis,
subacute
sclerosing
panencephalitis,
thrombocytopenia or even death.10 The mortality
rate reported by WHO is 10% in underdeveloped
nations where there are high rates of
malnutrition and poor health care. In
immunocompromised patients the fatality rate is
approximately 30%.2 Women infected while
pregnant may end up with miscarriage or
preterm delivery. Risk factors for severe measles
and its complications include malnutrition,
underlying immunodeficiency, pregnancy and
vitamin A deficiency.10
Diagnosis is made clinically, as well as, by
laboratory investigations including detection of
IgM antibodies or culture of virus. IgA
antibodies can be tested from the saliva of the
patients in whom phlebotomy is difficult.11 The
differential diagnoses are numerous including
dengue fever, drug eruptions, enteroviral
infections, fifth disease, rubella, Kawasaki
disease, Rocky Mountain spotted fever, roseola
and toxic shock syndrome.11
of exposure to the virus.7 The complications are
treated by supportive care which includes
antipyretics, treatment of dehydration, adequate
nutrition and antibiotics for eye, ear infections
and pneumonia. Two doses of vitamin A
supplements are given to children in developing
countries for prevention of eye damage and
blindness.11 Vitamin A supplements have been
shown to reduce the number of deaths from
measles by 50%.11
Prevention of measles is possible by vaccination.
First dose of measles vaccine is given at nine
months of age while second dose with triple
combination vaccine called MMR (measles,
mumps and rubella) at fifteen months and
booster dose at four to five years in developing
countries. In developed countries two doses at
fifteen to eighteen months and then at four to six
years of age are given.11 Side effects of the
vaccine are rare, with fever and pain at the
injection site being the most common. The
vaccine is less effective in HIV-infected infants
than in general population. People who recover
from measles remain immune from this disease
for the rest of their lives.
It is time for us to play our role in creating
awareness about cutaneous manifestations of
this viral infection among general public and
practitioners for early referral to tertiary care
hospitals for its management.

There is no specific antiviral treatment for
measles. Nonimmunized people, including
infants, may be given measles vaccination
within 72 hours of exposure to the measles virus,
to provide protection against the disease. The
symptoms are usually milder and transient even
if the person develops measles. Pregnant
women, infants and immunodeficient people
should receive immunoglobulins within six days
