Flu activity begins to spike across country

Data shows that the number of flu cases are likely to spike in the coming weeks.

According to data by the Department of Health and Human Services, flu illnesses typically pick up in January and February.

So far in North Carolina, there have been 10 flu-related deaths this flu season. That's slightly less compared to this time last year, but by February of 2018, the number of flu-related deaths skyrocketed to 200.

Across the country, the flu is considered to be widespread in two dozen states, including North Carolina.

The most common strain that's circulating is H1N1, which is more likely to affect young adults and children, rather than the elderly. However, health officials say the flu shot works better against that strain.

Experts say it takes about two weeks to build up immunity against the virus after getting vaccinated.

Flu season lasts until May.
