Cryptosporidiosis

Cryptosporidiosis is caused by the organism Cryptosporidium parvum. It is generally transmitted through contact with animals, drinking water contaminated with faeces, even through swimming pools. It is transmitted from person to person through the faeco-oral route.

Reservoir

The gastro-intestinal tract of infected humans, domestic and wild animals. Water contaminated with faeces.

Incubation Period

2 – 5 days

Signs and Symptoms

  • Watery diarrhoea
  • Abdominal cramps

Diagnosis

Stool microscopy and immunofluorescence.

Prevention

  • Good personal hygiene and careful hand washing especially persons in contact with animals.
  • Symptomatic cases are excluded from food handling especially food that will not be consequently cooked.
  • Children should be excluded from child care centres and school until their diarrhoea has stopped – preferably more than 48 hours from last episode of diarrhoea for children under 5 years of age and older children who are unable to maintain good personal hygiene.
  • Exclude symptomatic child carers from direct care of children.
  • Soiled articles should be disinfected.
  • Should avoid swimming in pools for 3 weeks after illness since oocysts can survive in chlorinated water.
