Which spots are associated with Measles infection?

Koplik spots are specifically associated with measles infection and serve as a classic clinical finding. These small, bluish-white lesions appear on the mucous membranes of the inside of the cheeks, usually a couple of days before the skin rash develops. They are considered an early sign of measles and can help healthcare providers make an accurate diagnosis.

The distinctive appearance and timing of Koplik spots in relation to the measles rash make them a key indicator of this viral infection. Understanding their significance is crucial as they can assist in identifying measles early, promoting timely management and intervention.

The other options refer to different conditions or types of rashes that are not associated with measles. For instance, fifth disease is caused by parvovirus B19 and is characterized by a "slapped cheek" rash in children. Cherry spots can refer to small cherry-colored lesions seen in various dermatological conditions, while roseola typically presents with a sudden onset of fever and a subsequent rash in young children.
