Avoid the crystal clear waters of Lake Malawi

With its crystal blue water and scorching African heat, many are further enticed to take a dip.

However, there are some hidden nasties in the lake that many should be aware of.

Writing in the Times, travel expert Richard Green has said that Bilharzia, or its more commonly known name Schistosomiasis, is in abundance in the lake and it is best to take swimming trips in it with caution.

Caused by a parasitic worm that can penetrate the skin, fever, chills and general fatigue can all be experienced if caught.

Although easily treatable it is an unpleasant condition, and visitors should always have a check up when they come home from a trip to the lake.

However, Mr Green says that "the crystal clear waters of Lake Malawi are impossible to avoid jumping into," and added that he had never had any health problems as a result.

It is always advisable to get good travel insurance if on a trip to destinations such as Lake Malawi, as health problems can often blight a trip as well as cause complications.
