Causes, symptoms, diagnosis and treatment

Leptospirosis is an infection caused by Leptospira, a bacterium. It is a zoonotic disease, which means it can infect both humans and animals, such as dogs.

The disease is mainly spread through contact with the urine of infected animals. In humans, this can occur due to contact with urine or contaminated soil or water.

Sometimes, leptospirosis causes mild flu-like symptoms or no symptoms at all. But it can also lead to serious complications, such as meningitis, and it can be fatal.

Let’s take a look at how leptospirosis is diagnosed and treated. We’ll also discuss the best ways to prevent illness in people and pets.

Types of Leptospirosis

There are two possible stages or types of leptospirosis:

anicteric syndrome

Anicteric syndrome is the first stage of leptospirosis.It’s a mild flu-like illness 90% case.

jaundice syndrome

If a person gets better but gets sick again, they will enter the second stage of leptospirosis. This form is called jaundice syndrome or Weil’s disease. It’s more serious.

Usually, this type of leptospirosis lasts for several weeks. It is less common than the first stage of leptospirosis.

Leptospirosis varies in the type and severity of symptoms.

Mild leptospirosis can cause:

In some cases, leptospirosis causes no symptoms at all.

Symptoms of severe leptospirosis include:

usually requires between 1 to 2 weeks Patients begin to experience symptoms, but it can take up to a month.

  • infected animal
  • Urine of infected animals
  • contaminated soil or water

Leptospirosis rarely spreads between humans.However, it may happen pregnancy period, through the placenta. This brings the risk of miscarriage.

Leptospirosis is common in animals. This includes farm, wild and domesticated animals. It is common in dogs but rare in cats.

Animals with leptospirosis may not have any symptoms. They may also release bacteria into the environment for months or years.

Dogs can be vaccinated against leptospirosis. The vaccine provides protection for at least 12 months, so it may need to be given annually. There is no leptospirosis vaccine for cats.

it is possible Humans contract leptospirosis from animals. This can occur through exposure to the urine of infected animals. It is rarely spread through animal bites.

Leptospira Commonly seen in:

  • cows
  • pig
