The CDC on 'Post Covid conditions'
The CDC seems to be trying to get away from the term long Covid and instead using the term 'post Covid conditions', perhaps because they are learning that for many, post Covid conditions resolve after a relatively short period of time:
CDC is using multiple approaches to estimate how many people experience post-COVID conditions. Each approach can provide a piece of the puzzle to give us a better picture of who is experiencing post-COVID conditions. For example, some studies look for the presence of post-COVID conditions based on self-reported symptoms, while others collect symptoms and conditions recorded in medical records. Some studies focus only on people who have been hospitalized, while others include people who were not hospitalized. The estimates for how many people experience post-COVID conditions can be quite different depending on who was included in the study, as well as how and when the study collected information. Estimates of the proportion of people who had COVID-19 that go on to experience post-COVID conditions can vary:
13.3% at one month or longer after infection
2.5% at three months or longer, based on self-reporting
More than 30% at 6 months among patients who were hospitalized
