Leptospirosis

Details: Published: 21 July 2021; Hits: 2332

Leptospirosis is a bacterial disease that affects humans and animals. It is caused by bacteria of the genus Leptospira. In humans, it can cause a wide range of symptoms, some of which may be mistaken for other diseases. Some infected persons, however, may have no symptoms at all.

Without treatment, Leptospirosis can lead to kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, respiratory distress, and even death.

Incubation Period: 7-10 days

Mode of Transmission:

The bacteria that cause leptospirosis are spread through the urine of infected animals, which can get into water or soil and can survive there for weeks to months. Many different kinds of wild and domestic animals carry the bacterium.

These can include, but are not limited to:

Cattle
Pigs
Horses
Dogs
Rodents
Wild animals

When these animals are infected, they may have no symptoms of the disease.

Infected animals may continue to excrete the bacteria into the environment continuously or every once in a while for a few months up to several years.

Humans can become infected through:

Contact with urine (or other body fluids, except saliva) from infected animals.
Contact with water, soil, or food contaminated with the urine of infected animals.

The bacteria can enter the body through skin or mucous membranes (eyes, nose, or mouth), especially if the skin is broken from a cut or scratch. Drinking contaminated water can also cause infection. Outbreaks of leptospirosis are usually caused by exposure to contaminated water, such as floodwaters. Person to person transmission is rare.

Signs and Symptoms:

Fever
Non-specific symptoms of muscle pain, headache
Calf-muscle pain and reddish eyes fro some cases
Severe cases result to liver involvement, kidney failure or brain involvement. Thus some cases may have yellowish body discoloration, dark-colored urine and light stools, low urine output, severe headache.

Treatment

Antibiotics duly prescribed by a physician.
i>Early recognition and treatment within two days of illness to prevent complications of leptospirosis, so early consultation is advised.
Intravenous antibiotics may be required for persons with more severe symptoms. Persons with symptoms suggestive of leptospirosis should contact a doctor

Prevention and Control

Avoid swimming or wading in potentially contaminated water or flood water.
Use of proper protection like boots and gloves when work requires exposure to contaminated water.
Drain potentially contaminated water when possible.
Control rats in the household by using rat traps or rat poison, maintaining cleanliness in the house.
Protective clothing or footwear should be worn by those exposed to contaminated water or soil because of their job or recreational activities.
