Fascioliasis in India
Gideon (www.GideonOnline.com) notes that a single Indian case (1980) of human fascioliasis was published in the world’s literature during 1969 to 1989.

In the latter area, sheep harbor both Fasciola hepatica and F. gigantica. F. gigantica has also been identified in Indian buffaloes (Bos bubal...

Incidence and Prevalence:
Hepatitis C is the most common cause of chronic liver disease in Egypt. The nationwide carriage rate in 1997 was estimated at 6 to 8 million, or 18.1% of the population – the highest rate in the world.
A study published in 2010 estimated the yearly rate at 500,000 new cases (0.7% of the population); while a study published in 2013 estimated the yearly rate at fewer than 150,000 cases. An analysis published in 2...
