Which of the following is a primary symptom of Norovirus?

1. Jaundice

2. Fever

3. Dehydration

4. Projectile vomiting

The correct answer is: Projectile vomiting

Projectile vomiting is a primary symptom of Norovirus, which is highly contagious and primarily spreads through contaminated food or surfaces, as well as person-to-person contact. Norovirus infections typically cause sudden onset gastrointestinal symptoms, including severe nausea, vomiting, diarrhea, and stomach cramps. Projectile vomiting specifically describes the forceful expulsion of vomit, which is characteristic of Norovirus due to the intense irritation it causes in the gastrointestinal tract. This symptom is often distressing and can lead to quick dehydration, especially in vulnerable populations such as children and the elderly. While the other options may relate to various medical conditions or infections, they are not primary symptoms of Norovirus. For instance, jaundice relates to liver issues, fever can accompany a range of illnesses but is not specifically tied to Norovirus, and dehydration, while a consequence of vomiting and diarrhea, is a result rather than a primary symptom. Understanding the specific symptoms of Norovirus aids in effective identification and management of outbreaks.
