IDPH reported bird flu outbreak in Illinois flocks, here's what you should know

PEORIA - Last month, the Illinois Department of Public Health (IDPH) has reported the state’s first bird flu cases in poultry flocks.

In a health advisory sent to long-term care (LTC) facilities, farm bureaus and local health departments, the IDPH reports large commercial poultry flocks in central and southern Illinois have recently tested positive for the H5N1 virus. Farm owners are now in the process of “de-populating” the birds.

Several counties in northern Illinois have reported events where many ducks and geese have died, referred to as “die-offs.” The reason LTCs received the notice is because many are located on retention ponds that attract waterfowl and wild birds.

No human cases have been reported in Illinois yet. But health officials continue to warn those who interact with potentially infected animals that if they don’t wear the proper personal protective equipment (PPE), they are at higher risk of developing the novel influenza A virus due to H5N1.

Doug Kasper, MD, an infectious disease specialist with OSF HealthCare, says bird flu has really hurt local American farms.

"Avian flu is a different strain of Influenza A. It's a strain that has been circulating in bird and cattle populations for over two years. It has been devastating to those populations, like poultry and dairy farms across the country," Dr. Kasper says. "What was unique was that in the calendar year 2024, was the first confirmed testing where the spread from an animal to a human occurred of this specific strain of influenza."

In early January, the Louisiana Department of Health reported the first-ever human bird flu death in the United States. The patient was reported to be over 65 years of age and had underlying medical conditions. The patient contracted H5N1 after exposure to sick and dead birds in a backyard flock.

Currently bird flu is only transmitted from animal to animal or animal to person. There have been no reported cases to have transmitted from human to human, but Dr. Kasper says there is always a concern about that possibility.

"Whenever there is an animal strain of infection that's not typically found in humans, we worry about the impact of if it were to cross over," Dr. Kasper says. "We've seen this with other infections throughout history. Even within COVID-19, there was the initial thought that it was an animal strain of infection."

The current flu vaccine does not protect against avian influenza, Dr. Kasper says.

"Each year the influenza vaccine, which is made up of three or four strains of influenza virus, is reexamined and matched up to a variety of factors to try and predict which strains will be most prevalent the next year," Dr. Kasper says. "Right now, avian flu cases in humans are so low that it doesn't warrant a different strain that would be much more likely to be found."

IDPH’s guidance to LTCs is to have residents tested for the flu if they are suspected of having acute respiratory illness. Don’t touch dead or sick birds, only trained staff in appropriate PPE should handle with caution.

"The average person who does not interact with poultry or dairy farms is at very low risk of avian flu," Dr. Kasper says.

There is concern that bird flu could enter the food production and distribution across America. This is why the United States Department of Agriculture (USDA) is closely monitoring dairy and poultry farms, to try and limit any possible contamination of dairy, meat or poultry products.

The bird flu continues to be rarely seen in humans, as only 67 cases (as of January 15) have been reported by the Centers for Disease Control and Prevention. Most cases have been mild, Dr. Kasper says.

Health experts say it is okay to get your flu and COVID shots at the same time

EVERGREEN PARK -- It happens every year: flu season, which typically peaks between December and February. This year will mark the third flu season with another virus also circulating: COVID-19. With an updated safe and effective COVID-19 booster shot now available, health experts are urging people to get both the flu and COVID vaccines in order to protect themselves this fall and winter.

Doctors recommend patients get both their flu and Covid booster by the end of this month for maximum protection against the two viruses.

Since 2010, the Centers for Disease Control and Prevention (CDC) has recommended annual flu vaccines for everyone six months and older, with few exceptions. New this year is an added recommendation for a higher dose for those 65 and older. The CDC has also recommended the use of updated COVID-19 boosters from Pfizer-BioNTech for people ages 12 years and older and from Moderna for people ages 18 years and older.

If you have not yet received your COVID-19 booster shot, or if you still have yet to receive an initial dose, it’s not too late.

"I urge everybody who is eligible to get a COVID booster to do so, and the reasons why are multifactorial. Number one is because your immunity wanes and you need to protect yourself. Number two is that the virus has changed slightly and the newest booster is most effective at protecting against those changes, " says Dr. Bill Walsh, an OSF HealthCare chief medical officer.

Dr. Walsh adds that it is important to get the seasonal flu shot as well as a COVID shot because they protect against different viruses.

"Please understand that the recommendation is for both the flu shot and the COVID shot. There is no cross reactivity even though the symptoms might be similar between COVID-19 and influenza. The influenza shot will not help against COVID, and the COVID vaccination will not protect you against influenza, " Dr. Walsh explains.

The timing of when to get your flu shot and COVID booster can be confusing. The CDC says if you haven’t yet gotten your initial recommended dose of the COVID-19 vaccine, to get one as soon as you can. Health experts typically recommend getting your seasonal flu vaccine by the end of October for best protection during the peak of flu season, and say it is safe to get both vaccines during the same visit.

"There are many times when you get more than one vaccine. Most of the time when you get a tetanus shot, it also includes pertussis. Many of the vaccinations pediatricians give to children have more than one vaccine in each shot. So, it is standard and normal for more than one vaccine to occur at a time, " Dr. Walsh says.

Dr. Walsh adds getting both shots done at once alleviates having to make multiple trips to your doctor’s office or local pharmacy. But this route may not be for everyone.

As with all vaccinations, there are mild side effects that both vaccines can cause, such as joint or muscle pain, fatigue, and chills. If you have experienced side effects from vaccines in the past and it took a couple days for them to subside, you may opt to get the vaccines at separate times.

"You know yourself best. If you are certain that you will get them both despite not getting them at one appointment, then that is completely fine, too. You may want to space them out because sometimes you have side effects. There have been a lot of questions about whether to get them both in one arm or in different arms so you have different injection sites. That really boils down to personal preference, " advises Dr. Walsh.

The important thing is making sure you do get both of these vaccinations to protect both yourself and your loved ones. Because the holiday season is approaching, you may have holiday gatherings on your calendar over the next few months. If you get your flu shot in October but choose to wait to get your COVID-19 booster at a later date, Dr. Walsh recommends getting it at least two weeks before any large gatherings in order to ensure the best protection against the virus.

To schedule your seasonal flu vaccine and COVID-19 booster, make an appointment with your primary care provider or local pharmacy. Talk to your primary care provider if you have any questions about either vaccine.
