Respiratory illness (Flu, RSV, COVID-19) current activity summary:
Flu activity is very high in Louisiana right now--at the highest level anytime in the past 10 years, and much earlier in the season than usual. If you have fever, body aches, and cough, please seek treatment if you have risk factors (health problems, or if you are an older adult), and try not to spread it to others. Fever and absolute misery for a solid 5 days is not unusual, and some have nausea, vomiting and diarrhea, especially with flu type B. Flu is not only miserable, but some people will develop pneumonia and other complications--even people who are otherwise healthy.
RSV is around and causing a lot of childhood illness and hospitalizations. Most adults will have nothing but a common cold from RSV, but young children and also older people are at increased risk of serious infection if they contract RSV.
With all the flu, RSV, and COVID-19 activity (see below), people who are older or have chronic health conditions should take care to avoid being around people who are sick, and consider wearing a high-quality medical or N95 mask when in crowded spaces. If you are sick, please do what you can to avoid spreading it to others, especially those at risk.
COVID-19 activity has been fairly low but is currently rising. While the current wave where it has occurred around the world has resulted in fewer cases and hospitalizations overall than Omicron did, it continues to cause serious illness and hospitalizations mainly among people 70 and older, which is what we are seeing in Louisiana now as well.
Should you get the COVID-19 bivalent booster? If you're vaccinated and it's been at least 2 months since your last dose of any COVID vaccine, the answer is yes. So far, immunity from both natural infection and from vaccination wanes over time, and the current variants are evading most prior immunity. We need a better strategy long-term (i.e., a nasal vaccine that protects against infection better and that more durably protects against multiple variants), but in the meantime, the vaccines remain effective to greatly reduce risk for serious infection...if you keep up with the recommended boosters.
I have taken flu vaccines annually for the past 30 years and have taken the COVID vaccine and all recommended boosters, including the currently available bivalent booster. I have never had the flu or COVID-19 yet. That's not to say I couldn't get one or both tomorrow, but I know my risk for infection and especially severe infection or hospitalization is greatly reduced, and I wouldn't recommend them unless I felt the benefits far outweighed any risks both for myself and for my patients.
