Cyclosporiasis is a parasitic infection that is typically transmitted through contaminated food or water and is most commonly reported during the summer months.

According to the US Center for Disease Control and Prevention (CDC), the outbreak has spread across 34 states, affecting nearly 7,000 people. Although the illness is rarely fatal, it can cause significant discomfort, with frequent watery diarrhoea being its most common symptom.

The agency classified the outbreak as a medium-level health risk and urged travellers to strengthen hygiene practices, particularly regarding the consumption of food and water.

The advisory comes during the peak summer vacation season, when travel between Mexico and the United States typically increases.

Health authorities noted that the exact source of the outbreak has not yet been definitively identified and therefore recommended that individuals maintain preventive measures throughout their trip and continue to be vigilant even after returning home.
