This historic image from the 1918 influenza pandemic depicts a nurse wearing a gauze face mask, alongside a public health advisory published in Illustrated Current News. It outlines early preventive measures such as avoiding close contact, covering coughs and sneezes, maintaining hygiene, seeking fresh air and sunlight, and wearing masks in sick rooms. Long before modern vaccines and antivirals, these simple behavioural interventions formed the cornerstone of infection control principles that continue to underpin public health responses to respiratory infections today.
