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]
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 36.8 ± 0.5 °C (98.2 ± 0.9 °F). [12]
Leptospirosis is treated in humans by the antibiotics penicillin and doxycycline. [7] [8] L. interrogans has many properties that ensure its optimal survival in specific conditions, including two periplasmic flagella for movement and mobility. These flagella enable L. interrogans to more easily access and infect both human and mammalian tissues ...
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3] [10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2]
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
Leptospira noguchii are spirochete-shaped, gram-negative bacterium that typically range from 0.1 μm by 6 μm to 0.1 μm to 20 μm. [9] [10] Leptospira noguchii also lacks glycolipids in their peptidoglycan and contain diaminopimelic acid. [10] L. noguchii is a motile organism due to having amphitrichous flagella on opposing ends of each other ...
Over 30 days at 0 °C (32.0 °F) (over one month at freezing temperature) 6 days at 37 °C (98.6 °F) (one week at human body temperature) decades in permanently frozen lakes; on hard non-porous surface such as plastic or stainless steel for 24–48 hours; on clothes, paper and tissues for 8–12 hours [6]
