Symptoms Of Listeriosis (Listeria)

Nausea And Vomiting

Gastrointestinal problems are also quite common with bacterial infections like listeriosis. Individuals might experience just nausea or vomiting, though both can make an appearance as well. Often, these symptoms, which are collectively known as gastroenteritis, will precede others and last about one to three days. However, they can go on longer in serious cases with at-risk populations, including pregnant women, older adults, young children, and anyone with a suppressed immune system. In most cases, these symptoms are considered mild and are not life-threatening. A doctor should properly treat prolonged symptoms, although they usually respond well to antibiotics.
