Leptospirosis is a blood infection caused by the bacterium Leptospira [8] that can infect humans, dogs, rodents and many other wild and domesticated animals. [8] Signs and symptoms can range from none to mild ( headaches , muscle pains , and fevers ) to severe ( bleeding in the lungs or meningitis ). [ 5 ]
Leptospira noguchii is another pathogenic bacteria that causes Leptospirosis. Leptospirosis can be transferred in a multitude of ways. Leptospirosis can transfer from animals to humans , humans to humans, or animals to animals via intake of contaminated body fluids, such as urine and blood. [7]
Leptospira (from Ancient Greek λεπτός (leptós) 'fine, thin, narrow, etc.' and Latin spira 'coil') [1] is a genus of spirochaete bacteria, including a small number of pathogenic and saprophytic species. [2] Leptospira was first observed in 1907 in kidney tissue slices of a leptospirosis victim who was described as having died of "yellow ...
Leptospirosis: Caused by bacterium of genus Leptospira: Water contaminated by the animal urine carrying the bacteria Begins with flu-like symptoms then resolves. The second phase then occurs involving meningitis, liver damage (causes jaundice), and kidney failure: Otitis Externa (swimmer's ear) Caused by a number of bacterial and fungal species.
The bacteria cause two phases of infection, the anicteric phase and the icteric phase. The anicteric phase of infection is commonly known as phase one, in which humans exhibit fever, headache, and nausea. The icteric phase, or phase two, includes more severe symptoms including hemorrhages and renal tubular failure. [5]
It was first detected in December 2019, which is why scientists called it COVID-19 (coronavirus disease 2019). [39] This outbreak has since caused a health issue in the city of Wuhan, China which evolved into a global pandemic. The World Health Organization officially declared it a pandemic on March 11, 2020.

Conjunctival suffusion is an eye finding occurring early in leptospirosis, which is caused by Leptospira interrogans. Conjunctival suffusion is characterized by redness of the conjunctiva that resembles conjunctivitis , but it does not involve inflammatory exudates. [ 1 ]
Leptospirosis is a potentially lethal disease in humans that occurs all around the world (except in polar regions). [2] [3] Leptospirosis is caused by the bacterium Leptospira, a helix-shaped bacterium that is dependent on high humidity for survival. [2]
