Norovirus, commonly known as the 'stomach bug,' is notorious for causing nausea, vomiting, and diarrhea. However, this year has seen a surge in cases, and experts are reminding the public that norovirus can also present with symptoms like fever, headache, and fatigue. This article delves into the various symptoms of norovirus, including the less common ones, and provides advice on how to manage the illness and prevent its spread.
Nick Blackmer is a librarian, fact-checker, and researcher with over 20 years of experience in consumer-facing health and wellness content. Norovirus, also known as the ' stomach bug ,' is a common illness that causes nausea, vomiting, and diarrhea. While these are the typical symptoms associated with norovirus, experts have noted that individuals experiencing norovirus infections may also exhibit symptoms commonly found in other viral infections, such as fever, headache, and fatigue.
This year has seen an unusually high number of norovirus cases, and experts are closely monitoring the situation. According to the latest data from the Centers for Disease Control and Prevention (CDC), there were 426 norovirus outbreaks in the 14 states participating in the NoroSTAT Surveillance Network in December, and the first two weeks of January saw 225 outbreaks. This surge surpasses the highest number of outbreaks recorded during 2012-2020, highlighting the current severity of the situation. Dr. Daniel Edwards, a physician in the Division of Pediatric Infectious Diseases and associate medical director for Pediatric Infection Control at University Hospitals Rainbow Babies & Children’s Hospital, explains that two individuals infected with the same virus can present with slightly different symptoms. While nausea, vomiting, and diarrhea remain the hallmark symptoms of norovirus, individuals may also experience fever, headache, body aches, chills, and fatigue. Dr. Edwards emphasizes that these additional symptoms are typical of viral infections, occurring when the immune system mounts a response to fight off the invading virus. It's important to note that some individuals infected with norovirus may not experience any symptoms at all. The severity and type of symptoms depend on factors such as the individual's immune system strength, the environment, and the viral load.Dr. Edwards states that higher viral loads are often associated with more severe or symptomatic disease. Unfortunately, there is no known way to accelerate the healing process for norovirus. The best course of action is to focus on rest, hydration, and supportive care. Norovirus is highly contagious and notoriously difficult to eliminate. It can persist on surfaces for weeks and requires the use of bleach for effective disinfection. The virus also mutates rapidly, leading to a lack of long-lasting immunity in individuals. Dr. Sood advises that meticulous attention to hygiene and environmental cleanliness is crucial to minimize the spread of norovirus among family members.
