Measles is a severe viral infection characterized by fever, cough, runny
nose, conjunctivitis, and a distinctive rash. It spreads through
respiratory droplets and can lead to complications like pneumonia and
encephalitis [1-3]. Despite the availability of measles vaccines,
outbreaks still occur due to vaccine hesitancy and incomplete
immunization coverage [2].
A 42-year-old Caucasian man with no significant medical history,
presented to the emergency room with fever, cough, odynophagia and a
skin rash with 3 days of evolution, 10 days after returning from Brazil.
On admission, the tympanic temperature was 39.2°C. Physical examination
revealed a cephalocaudal maculopapular rash that spread across his face,
chest, and extremities (Figures 1 and 2), and multiple 1–2 mm
grey–white spots on the buccal mucosa consistent with Koplik’s spots
(Figure 3).
Measles was suspected based on the associated symptomatology and
Koplik’s pathognomonic sign, and he was placed in isolation.
Oropharyngeal swab, urine and blood specimens were taken. The diagnosis
was confirmed by positive polymerase chain reaction (PCR) for measles.
Serological tests using enzyme immunoassay were also performed revealing
IgM antibodies against measles (IgM titer 8.4, positive ≥ 1.1; IgG titer
9.0; positive ≥ 16.5), compatible with acute infection.
He received supportive care and within a few weeks all his symptoms
disappeared.
There is an increase in new cases of measles in developed countries
where vaccination is optional. This case demonstrates the importance of
continuing to include measles in the differential diagnosis, even in
countries where this disease has been eliminated, since cases can arise
in other countries and easily cause outbreaks.
The role of the otorhinolaryngologist as a public health agent is
reinforced preventing transmission and implement control measures.
Attention should also be drawn to the need for measles vaccination for
all health care providers.
