Measles is a condition, that is best diagnosed clinically based on a constellation of signs and symptoms. Fever, rash and conjunctivitis are 3 major physical findings that must be looked out for, while making the diagnosis of measles.^[1][2]

• A high fever is always present, it could be as high as 105°F.

• Tachycardia may be present, specially with the onset of fever.

• Tachypnea may be present, specially in patients complicated with pneumonia.

• Three to five days after the start of symptoms, a red or reddish-brown itchy rash appears.
• The rash usually begins on a person’s face at the hairline and spreads downward to the neck, trunk, arms, legs, and feet.
• It also regresses in the same manner as it appeared in about 5-7 days.
• The rash is blanching, maculopapular in nature to begin with but may coalesce later to become plaques and patches.
• When the rash appears, a person’s fever may spike to more than 104°F.
• Shown below are images depicting the characteristic rash of measles.

• Koplik’s spots are tiny white spots with erythematous base and bluish-white centers found inside the mouth at the base of second molars.
• These appear usually 2-3 days after initial prodrome and may or may not persist until the rash disappears.
• Although they are pathognomic, Koplik’s spots are not present in all the cases.
• Its absence does not exclude the diagnosis of measles.
