Leptospirosis occurs worldwide and is a common mild to severe health problem for humans and animals, particularly in areas with a hot and humid climate. The natural reservoirs for leptospirosis are rodents as well as a large variety of domesticated mammals.
Human infection is caused by Leptospira interrogans, the pathogenic member of the genus of Leptospira. The infection is spread via urine from the host animal; hence human infection is through ingestion of urine-contaminated water and food.
After infection, leptospires are present in the blood until they are cleared after 4 – 7 days following the production of anti-leptospira interrogans antibodies, initially of the IgM class, followed by the IgG class. After 7 days, the bacteria can be found in fresh urine.
Leptospirosis infection in humans causes a wide range of symptoms, and some infected persons may have no symptoms at all. Leptospirosis is a biphasic disease that begins suddenly with fever, accompanied by chills, intense headache, severe muscle ache, abdominal pain, vomiting, diarrhoea, red eye, and occasionally a skin rash.
There are 2 phases of the infection:
We are proud to announce our latest test, the Leptospira IgM/IgG screen test. The test is a qualitative serology screen for the detection of Leptospira IgM/IgG antibodies in human serum or plasma. For more information, please call the laboratory.
