If a person has a leptospirosis, will it be pass to his partner if they have sex intercourse ?

No.: Leptospirosis is transmitted from animals to people. It is not known to be transmitted from person to person.

Unlikely: This spirochaete can enter the body through skin or mucous membranes, especially if there are breaks in the skin. 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, but never say never.

Rarely: Leptospirosis is caused when a bacterium (Leptospira interrogans) which is stored in animals kidneys is released through urine & contaminates soil or water. If you drank infected water you could become infected. It can also enter your body through breaks in your skin, nose, mouth & genitals. In rare cases it has been passed through breastfeeding & sex. It can be ID'ed wi antibodies.
