Alberta Health Services said that a medical clinic in Calgary's Westhills area was the site of a potential measles exposure [1].

This alert is critical because measles is highly contagious and can spread rapidly among unvaccinated individuals in public spaces. Prompt identification of exposed persons is necessary to prevent a wider community outbreak.

Provincial health officials said the exposure occurred on May 11 [2]. The risk is limited to those who were present at the clinic during a two-hour window in the late morning [1].

"Anyone who may have been there in a two‑hour timeframe in the late morning may be exposed," an Alberta Health Services spokesperson said [1].

Health authorities are monitoring the situation to ensure that those who may have come into contact with the measles-positive individual receive appropriate medical guidance. The province identified the specific location in the Westhills neighborhood to narrow the scope of the alert [2].

While some reports mentioned other locations, the provincial health authorities focused their specific clinic warning on the Westhills site [1]. Health officials said that individuals should check their vaccination records and contact a healthcare provider if they believe they were at the clinic during the specified time [1].

Anyone who may have been there in a two‑hour timeframe in the late morning may be exposed.

This targeted alert reflects a public health strategy to contain the virus by identifying a narrow window of exposure. By specifying the two-hour timeframe and the exact neighborhood, Alberta Health Services aims to minimize public panic while ensuring high-risk individuals seek immediate screening or vaccination.
