Unwanted souvenir of holidays... snail fever

A TROPICAL disease may seem an unlikely risk for Scots.

But researchers are warning that snail fever – also known as schistosomiasis or bilharzia – is becoming a ‘significant public health concern’ in Scotland.

A study has found up to 25 per cent of those returning home from regions where the disease is endemic are testing positive.

Parasitic worms released from infected snails in fresh water can burrow into the skin during activities such as washing or swimming. Those infected can suffer liver and lung damage and even cancer if not treated.

Early signs include itchy skin bumps, fever and abdominal pain. But many people do not

Consultant clinical scientist Dr Claire Alexander said: ‘This report provides evidence to highlight imported schistosomiasis as being a significant public health concern in Scotland, particularly as the disease is likely to be underestimated.’

She added: ‘Of concern were the large number of positive travellers, most of whom were asymptomatic when tested.’
