Norovirus Cases on the Rise in U.S., CDC Data Shows
According to recent data from the Centers for Disease Control and Prevention (CDC), cases of norovirus are increasing in the United States, particularly in the Northeast region. In the week ending Feb. 17, over 12% of tests for norovirus came back positive, up from 11.5% the previous week. In the Northeast specifically, over 13% of tests were positive, with positivity rates consistently over 13% since late January.
Despite the rising numbers, current levels are actually lower compared to last season when about 15% of tests were positive. Norovirus outbreaks are most common in the late fall, winter, and early spring months.
Norovirus is the most common cause of acute gastroenteritis in the U.S., causing 19-21 million illnesses each year. The virus can spread through direct contact, consumption of contaminated food or liquids, or touching contaminated surfaces. Common symptoms include diarrhea, vomiting, nausea, and stomach pain.
There is no specific treatment for norovirus, but drinking plenty of liquids is recommended to avoid dehydration. To prevent illness, the CDC recommends washing hands frequently, rinsing fruits and vegetables, and cooking shellfish thoroughly.
In related news, the Food and Drug Administration (FDA) issued a warning in January against the sale and consumption of certain oysters from Baja California and Mexico due to potential norovirus contamination. Additionally, in December, over 200 suspected cases of norovirus were linked to a sushi restaurant in North Carolina.
It is important for individuals to take precautions to prevent the spread of norovirus and stay informed about recent outbreaks in order to protect themselves and others from illness.
