Chicago, Illinois United States of America
CDC recommends that everyone ages 6 months and older receive an updated COVID-19 vaccine when it becomes available this fall
COVID-19 cases are on the rise in both Chicago and the US
Emergency room visits due to COVID-19 have increased by 23% in the past week, but hospitalization rates remain steady
FLiRT variants account for a significant proportion of these cases in Chicago and nationally
LB.1 variant is currently the third-leading COVID-19 variant in the US, making up 15% of cases

Rising COVID-19 Cases in Chicago and the US: The Role of FLiRT and LB.1 Variants

COVID-19 cases are on the rise in both Chicago and the United States, with at least 44 states experiencing an increase or likely increase in COVID-19 infections as of late June. The highly contagious KP.3 and KP.2 strains, also known as FLiRT variants, account for a significant proportion of these cases.

In Chicago specifically, six out of the city's seven sewershed areas have seen rising levels of COVID-19 over the past three weeks. The sharpest rise has been observed in Lincoln Park and the Near North Side. More than half of local cases come from FLiRT variants.

Nationally, emergency room visits due to COVID-19 have increased by 23% in the past week, but hospitalization rates remain steady. The CDC recommends that everyone ages 6 months and older receive an updated COVID-19 vaccine when it becomes available this fall, regardless of whether they have been vaccinated before.

The LB.1 variant is currently the third-leading COVID-19 variant in the US, making up 15% of cases. Symptoms of LB.1 are similar to those caused by the FLiRT variants and include sore throat, cough, fatigue, congestion, runny nose, fever or chills, headache, and muscle aches.

William Schaffner expects an increase in COVID-19 cases during summer months as it doesn't disappear like influenza does. The CDC also recommends that those who are older than 65 and immunocompromised should get the latest vaccine or another vaccine if four months have elapsed since their last one.

    The article provides information from reputable sources such as the Centers for Disease Control and Prevention (CDC) and experts in the field. However, there are instances of selective reporting and emotional manipulation that lower the score. The author focuses on the increase in COVID-19 cases due to new variants without mentioning that vaccines have been effective at preventing serious illnesses, hospitalizations, and deaths. This creates a sense of fear and concern without providing a complete picture. Additionally, the article mentions anecdotal evidence from social media about nasty effects from the virus but does not provide any context or verification for these claims.
    • A commentator for CNBC recently wrote on X: Tests positive for COVID a few days ago. First three days of symptoms were worse than those of 2 years ago. Deep, lingering sore throat among them. Thank goodness for Paxlovid. Seems to be working.
    • COVID figures are trending up due to a constellation of factors, including more people congregating close together, more people traveling, and more people going indoors to escape extreme heat.
    • The newest highly transmissible variant leading a significant amount of infection is LB.1, which is causing an estimated 1 in 10 new cases.
