What are onchocerciasis symptoms and signs?

The symptoms and signs of onchocerciasis are as follows:

  • Skin inflammation that is very itchy and forms papules on the skin
  • Nodules in the skin (subcutaneous nodules or bumps)
  • Scarred, saggy, or drooping areas of skin
  • Patchy skin depigmentation (leopard skin)
  • Lymph node inflammation (lymphadenitis)
  • Eye (ocular) lesions (eye itching, redness, or swelling)
  • Visual problems (visual impairment and/or inability to distinguish certain colors, partial or complete blindness)
  • Eosinophilia (unusually high levels of eosinophils in the blood)
  • "Sowda" is a term used to describe the severe itching and skin discoloration (darkening), that is often confined to one limb, that can be found with onchocerciasis.

Is there an incubation period for onchocerciasis?

Although the infection with larvae begins immediately, the disease may not become apparent in an individual for months to years. In most individuals, it develops slowly in the skin although some patients may present initially with eye problems.
