As Alaska sees a spike in Flu cases — another virus is on the rise in the U.S.

FAIRBANKS, Alaska (KTUU) – Alaska has recently seen a rise in both influenza and respiratory syncytial virus, better known as RSV. Amidst the spike in both illnesses, norovirus has also been on the rise in the United States. The Centers for Disease Control and Prevention (CDC) says it’s highly contagious and hand sanitizers don’t work well against it.

Current data for Alaska shows 449 influenza cases and 262 RSV cases for the week of Jan. 4. Influenza predominantly impacts the Kenai area, the Yukon-Kuskokwim Delta, and the Northwest regions of the state. RSV is also seeing significant activity in the Yukon-Kuskokwim Delta and Anchorage.

Both are respiratory viruses that are treatable, but norovirus — which behaves like the stomach flu according to the CDC — is seeing a surge at the national level. It “causes acute gastroenteritis, an inflammation of the stomach or intestines,” as stated on the CDC webpage.

This virus is spread through close contact with infected people and surfaces, particularly food.

“Basically any place that people aggregate in close quarters, they’re going to be especially at risk,” said Dr. Sanjay Gupta, CNN’s Chief Medical Correspondent.

Preventing infection is possible but does require diligence. Just using hand sanitizer “does not work well against norovirus,” according to the CDC. Instead, the CDC advises washing your hands with soap and hot water for at least 20 seconds. When preparing food or cleaning fabrics — the virus “can survive temperatures as high as 145°F,” as stated by the CDC.

According to Dr. Gupta, its proteins make it difficult to kill, leaving many cleaning methods ineffective. To ensure a given product can kill the virus, he advises checking the label to see if it claims it can kill norovirus. Gupta said you can also make your own “by mixing bleach with water, 3/4 of a cup of bleach per gallon of water.”

For fabrics, it’s best to clean with water temperatures set to hot or steam cleaning at 175°F for five minutes.

As for foods, it’s best to throw out any items that might have norovirus. As a protective measure, it’s best to cook oysters and shellfish to a temperature greater than 145°F.

Based on Alaska Department of Health data, reported COVID-19 cases are significantly lower than this time last year.
