Last week, a public school in Waterloo issued a warning to parents about a suspected case of scarlet fever, a disease that has been off the federal government's tracking radar since 1978. This alarming situation has brought back memories of a time when the illness was far more prevalent and considered potentially fatal.

In an official statement, the Waterloo Region District School Board (WRDSB) confirmed that they notified parents via email regarding the potential case while providing updates a couple of days later. The communication included vital health information and resources from the Canadian Paediatric Society to help families understand the situation better.

Officials emphasized their collaboration with Region of Waterloo Public Health, asserting that they would adhere to any guidance issued by health authorities. Parents were encouraged to reach out for health-related information or clarifications.

Scarlet fever, once a major health concern, was tracked from 1924 until 1978 when it was deemed non-invasive, leading to an end in federal tracking. During its peak years in the late 1970s, there were over 20,000 reported cases annually, signaling a public health crisis of sorts. The rise of antibiotics transformed how we view this disease, turning it from a once-fatal infection into a manageable illness.

Although scarlet fever itself is not reportable, public health officials have reminded parents that infections can usually be treated efficiently with antibiotics. Group A Streptococcus (Group A Strep) – the bacteria responsible for scarlet fever – can spread through direct contact with droplets from the nose or throat of an infected individual or through contact with infected skin sores. While rare, there are more severe infections associated with Group A Strep, known as invasive Group A Strep (iGAS), which are reportable and prompt immediate public health action.

In light of the rising concerns during winter, where respiratory infections thrive, Waterloo Public Health has issued preventive measures. Here are some recommendations for families to help avoid Group A Strep infections and other common illnesses: 1. **Stay up-to-date with vaccinations if eligible.** 2. **Stay home if you feel unwell.** 3. **Cover your coughs and sneezes to curb the spread of germs.** 4. **Wash your hands frequently to maintain hygiene.

The awakening of scarlet fever awareness has left many parents concerned, leading to discussions about school health protocols and the importance of vigilance when it comes to childhood illnesses. Is this a sign of rising health threats in our communities, or merely a flash of historical concerns? Only time will tell. Stay alert and informed, Waterloo!
