No, jaundice is not contagious.
Jaundice is a result of metabolic interruption, often caused by an obstruction of the bile ducts. Because the bile cannot leave the body naturally (in your faeces), it enters the blood stream and turns you yellow.
A common cause of jaundice is gallstones, so jaundice is no more contagious than gallstones!
The primary way that SARS appears to spread is by close person-to-person contact
Germs can be spread b close conact with a person who has the germ.
It is spread by exchanging respiratory and/or throat secretions (for example, by kissing or by coughing on a person), or by lengthy contact (close living quarters) with an infected person.
Lice can spread quickly from person to person through direct head-to-head contact. It typically takes only a few seconds of close contact for lice to move from one person to another.
repeated close quarter exposure to infected person
Cavities are not contagious and cannot be spread from person to person. However, certain bacteria that contribute to cavities can be shared by sharing utensils, kissing, or through other close contact. Good oral hygiene practices can help prevent the spread of cavity-causing bacteria.
Scabies mites are usually spread through close, prolonged skin-to-skin contact with an infected person. Common ways of transmission include sexual contact, sharing bedding or clothing with an infected person, and living in crowded or close quarters where the mites can easily spread.
The Q fever is contagious. It can be spread to another person via air, saliva, cough, close contact, bodily fluids, blood, etc.
Usually, a bite from a flea off an infected rat would do it, but it could also be spread from person to person through close contact.
Strep Throat, or Streptococcal pharyngitis, is spread from person to person by coughing, sneezing, fluid contact, or any close contact with an infected individual.
E. coli can spread from person to person primarily through the fecal-oral route. This can occur when an infected person does not wash their hands properly after using the bathroom and then touches surfaces or food that others may consume. It can also spread through contaminated water or food, especially in settings where hygiene practices are inadequate. Close contact with an infected person, such as caregiving, can further facilitate transmission.
The same way they spread it to people, by coughing or sneezing close to the pig, touching things that the pig puts in its mouth or licks or touches with its nose, or by petting and touching the pig's eyes, or close to their mouths or snouts when they have the virus on their hands.
