As cold and flu season sweeps through the nation, another illness is making headlines: norovirus. Recent data from the Centers for Disease Control and Prevention (CDC) reveals a significant spike in norovirus cases, with 91 suspected or confirmed outbreaks reported across the country during the week of December 5. This marks a stark increase from the 41 outbreaks recorded during the same week in previous years from 2021 to 2024. Essentially, norovirus is more prevalent now than ever.

Norovirus is not to be taken lightly; it often causes severe vomiting and diarrhea, leading to a highly unpleasant experience for those infected. If you want to stay informed and reduce your chances of contracting this virus, it's vital to recognize its symptoms and how to respond if you do get sick.

According to Dr. Amesh A. Adalja, an infectious disease expert and senior scholar at the Johns Hopkins Center for Health Security, the initial symptoms of norovirus hit quickly, usually starting with nausea and/or vomiting. Other symptoms may include stomach pain, fever, headache, and body aches, as noted by the CDC.

The virus is known for its contagious nature, spreading through various means. You can become infected by direct contact with an infected person, consuming contaminated food or beverages, or touching surfaces or objects tainted with norovirus and then touching your face. Alarmingly, the virus can survive on hard surfaces for up to 12 hours, and it can linger on carpet for as long as 12 days—an unsettling fact for maintaining hygiene in homes.

Currently, there is no specific treatment for norovirus. Antibiotics are ineffective against this virus. Instead, supportive care is crucial. Dr. Adalja recommends staying hydrated by taking small sips of fluids and using acetaminophen for body aches and fever. Typically, most individuals recover within one to three days; however, you may still be contagious for up to two weeks even after feeling better.

Protecting yourself from norovirus is paramount, especially for vulnerable groups such as young children and the elderly, who may be more prone to dehydration. To minimize your risk, it’s advisable to avoid close contact with visibly ill individuals and practice frequent handwashing.

In conclusion, while norovirus is a common virus that most people encounter multiple times in their lives, being vigilant in washing hands and avoiding contaminated surfaces can help lessen your chances of infection. Stay safe, stay informed, and be proactive in safeguarding your health during this significant surge in norovirus cases.
