Leptospirosis is a potentially deadly bacterial disease that affects both humans and animals..
Also known as also known as Weil’s disease, it is found all over the world, including in the UK, but generally is more of a problem in hot places.
The bacteria enter the body through cuts and abrasions on the skin, through the mucous membranes of the mouth, nose and eyes but person-to-person transmission is rare.
In the early stages of the disease, symptoms include high fever, severe headache, muscle pain, chills, and redness of the eyes.
Those infected can also experience abdominal pain, jaundice, haemorrhages in the skin and mucous membranes, vomiting, diarrhoea, and rash.
Most cases of human leptospirosis are spread through rats' urine.
The best way to avoid the disease in the tropics is by wearing protective footwear while walking through water.
