Flu Spread Hits Maryland For Christmas

BALTIMORE, MD — Feel awful? You're not alone, with more cases of the flu reported across Maryland in the past two weeks, says the Centers for Disease Control. There's still time to get a flu shot before you travel to holiday gatherings — what are the odds someone there has a virus that gets shared?

For the week ending Dec. 16, Maryland and Virginia were among 23 states that reported widespread flu activity. That means Maryland saw outbreaks of flu or increased influenza-like illness, including recent laboratory confirmed influenza statewide, with more than 30 people requiring hospital care for the flu in Maryland.

Widespread influenza activity was also reported in Alabama, Arizona, Arkansas, California, Connecticut, Idaho, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Mississippi, Missouri, New York, North Dakota, Ohio, Oklahoma, Oregon, South Carolina, Texas, and Wisconsin.

While it's difficult to predict when flu activity will peak in the U.S., the CDC said after low flu activity in October, cases have steadily increased since early November, especially in the South. Flu activity in the U.S. generally begins as early as October and can last as late as May. According to the CDC, flu activity generally peaks sometime between December and February.

The Maryland Department of Public Health hasn't updated its flu count, with the agency reporting that for the week ending Dec. 9, influenza-like illness intensity in Maryland was minimal with regional geographic activity. The proportion of outpatient visits for flu cases reported by health-care facilities both increased slightly.

Clinical laboratories reported an increase in the proportion of specimens testing positive for influenza; 34 patients tested positive for influenza at the MDH lab. There were 35 hospitalizations for the flu that week in Maryland. One respiratory outbreak was reported to state health workers.

Here's what you need to know about the upcoming flu season:

Get Your Flu Shot
The CDC says getting a flu shot is currently the most effective method of avoiding the flu. While vaccine effectiveness can range from season to season, the CDC says a majority of cases reported so far — while small — have been characterized as being similar to the recommended 2017-18 Northern hemisphere flu vaccine components. According to the CDC, this suggests that getting vaccinated should provide similar protection as past seasons.

The CDC recommends getting your flu shot by the end of October as it takes two weeks for antibodies to develop that protect against the flu. Getting vaccinated later is still beneficial, the CDC says.

Difficult To Tell Which Flu Strain Will Dominate The Season
The CDC says it is difficult to determine what flu virus will dominate the season but flu vaccine is less effective against the currently circulating A(H3N2) virus. In past flu seasons when A(H3N2) has dominated, hospitalizations and deaths were more common. Influenza A viruses have been most commonly identified since Oct. 2017 with A(H3N2) viruses predominating, according to the CDC.

Looking To Flu Season In Australia
A report published in the New England Journal of Medicine on Thursday says that reports from Australia about the flu season there have caused mounting concern for what might be in store for the U.S. The flu season in Australia saw record-high numbers of confirmed flu cases and outbreaks and higher-than-average hospitalizations and deaths.

The A(H3N2) virus dominated in Australia and the preliminary estimate of vaccine effectiveness against the strain was only 10 percent, the NEJM reports.

"The implications for the Northern Hemisphere are not clear, but it is of note that the vaccine for this upcoming season has the same composition as that used in the Southern Hemisphere," the journal said.
Still, the NEJM says that while the flu vaccine may be imperfect its always better to get vaccinated than not to get vaccinated.

Flu-Related Deaths So Far
Of all deaths in the U.S. during the week ending Dec. 16, 6.2 percent were related to pneumonia and influenza, the CDC reports. That percentage is below the epidemic threshold of 7.4 percent. As of Dec. 16, the CDC also reported nine lab-confirmed pediatric deaths during the 2017-18 flu season.
