Worms

  • What are they?

    Parasitic worms (helminths) can be found in the human intestinal tract, urinary tract or bloodstream.

  • Global burden

    The Global Burden of Disease study estimates the magnitude of health loss due to diseases and injuries.

  • How do they spread?

    Infection with STH and schistosomiasis is associated with inadequate sanitation and hygiene, while LF is transmitted by mosquitoes.

  • Control & elimination

    Commitment to NTD control has increased in recent years, including periodic deworming campaigns with safe, cheap drugs.

  • How are they diagnosed?

    Reliable and sensitive diagnostic tests are essential for all NTD control programmes, including those for worms.

  • Geotargeting

    Geographical targeting of interventions is required to ensure programmes are implemented appropriately, focusing resources on areas of greatest need.
