Wobei man auch hier sagen muss - ist bei Grippe auch so. Das ist daher nichts, Covid typisches, sondern typisch für schwere Atemwegserkrankungen und Virusinfektionen.

In this Japanese population‐based cohort, the risk of new‐onset type 1 diabetes may increase after the diagnosis of influenza. These results, which must be confirmed in other populations, suggest that influenza may be a causal factor for new‐onset type 1 diabetes. The molecular mechanisms underlying the potential etiological relationship between influenza and type 1 diabetes should be elucidated.

Heart Complications
Respiratory illnesses can cause a heart attack, according to a 2018 study in the New England Journal of Medicine (NEJM). In this study, researchers found that the risk of having a heart attack was six times higher during the week after being diagnosed with the flu compared to the year before or after a flu infection.
Influenza has been linked to an increased risk of heart complications. Roughly half of the adults that are hospitalized due to the flu also have heart disease, according to the CDC. And another study from 2020 in the Annals of Internal Medicine found that heart complications occurred in 12% of the patients that were hospitalized with the flu.
"Most people who have studied this agree that two to four weeks, and maybe even into that second month, there is an increased risk of heart attack and stroke," said William Schaffner, MD, an infectious disease specialist at Vanderbilt University. But the message hasn't yet reached the general public, Dr. Schaffner added, or even a lot of healthcare providers. "When I mention this to doctors during continuing education classes, they sit up in their chairs; they've never heard this before."
Secondary Infections
The flu can also do a number on the immune system, which can leave people vulnerable to other illnesses and infections—like pneumonia, for example, according to the American Lung Association.
"After most viral illnesses, your white blood cell count is going to be low," Dr. Nachman said. If you're scheduled for any routine testing after a bout with the flu, be sure to mention it to your healthcare provider so they know that it could be a factor in your results.
For older adults, getting the flu could be the first step in a continual downward spiral when it comes to their health and their ability to take care of themselves. Not only do older adults face a higher risk of serious complications and death while they have the flu, but they're also at greater risk of reduced quality of life afterward, said Dr. Schaffner.
That loss of muscle tone and strength is especially dangerous for older adults, but it's also likely to affect younger flu victims as well to a lesser extent, said Dr. Schaffner. Exercise after the flu can help you feel better, Dr. Schaffner added, but he recommended starting with a low-intensity activity like brisk walking. "When I've gone back to the gym after having influenza, I've reduced my weights and my reps for some time before I work my way back up to normal," Dr. Schaffner said.
Das soll die Gefahren durch eine Corona Infektion nicht klein reden. Die sind real, es ist aber nichts, was Covid grundlegend von Infektionen wie der Grippe unterscheidet.
