There has been an outbreak of cryptosporidiosis, sometimes called crypto, identified in Wellington. This is a microscopic parasite that can cause diarrhoea, stomach cramps, and vomiting. In this case, it appears to have been spread through the local region’s public swimming pools.
Common symptoms include: smelly, watery diarrhoea, stomach cramps, lack of appetite, weight loss, fever, nausea and vomiting. Symptoms for most people will stop within a few days to a week. In the meantime, it is crucial to stay hydrated. If symptoms persist for longer than a week, or the sick person is concerned, they should contact their health provider or Healthline.
