A large proportion of the world's population has some form of immunity against SARS-CoV-2, through either infection ('natural'), vaccination or both ('hybrid'). This retrospective cohort study used data on SARS-CoV-2, vaccination, and hospitalization from national health system from February 2020 to June 2022 and Cox regression modelling to compare those with natural immunity to those with no (Cohort1, n = 94,982), hybrid (Cohort2, n = 47,342), and vaccine (Cohort3, n = 254,920) immunity. In Cohort 1, those with natural immunity were at lower risk for infection during the Delta (aHR 0.

We aimed to assess the common features and differences in the post-acute phase of COVID-19 compared with other non-chronic respiratory infections (RESP) using population-based electronic health data. We applied the self-controlled case series method where prescription drugs and health care utilisation were used as indicators of health outcomes during the six-month-long post-acute period.

Objectives: To assess COVID-19 fear and investigate factors associated with higher fear among COVID-19 survivors over 6 months after infection.
Methods: Cross-sectional study using multistage sampling (family practices within the highest 5th percentile of numbers of SARS-CoV-2 infected patients and random sample of patients within these practices) performed from March 15 to 17 July 2021.
SARS-CoV-2 vaccination is currently the mainstay in combating the COVID-19 pandemic. However, there are still people among vaccinated individuals suffering from severe forms of the disease. We conducted a retrospective cohort study based on data from nationwide e-health databases.

- Post-acute COVID-19 sequelae involve a range of health issues affecting different organ systems experienced by individuals after the initial COVID-19 infection.
- A nationwide cohort study assessed 3,949 hospitalized COVID-19 patients and 15,511 matched controls to determine long-term outcomes, including all-cause mortality and the development of new clinical issues.
- The study found that 40.3% of COVID-19 patients experienced at least one new clinical complication within a year, with significantly higher risks for conditions like dementia, respiratory disease, and heart disease compared to the general population.
Background: COVID-19 pandemic has led to overloading of health systems all over the world. For reliable risk stratification, knowledge on factors predisposing to SARS-CoV-2 infection and to severe COVID-19 disease course is needed for decision-making at the individual, provider, and government levels. Data to identify these factors should be easily obtainable.

Methods: Nationwide cohort study using electronic health care data on SARS-CoV-2 RNA positive cases (n= 66,287) and reference group subjects (n=254,969) with linkage to SARS-CoV-2 testing and death records.
Findings: People infected with SARS-COV-2 had more than three times the risk of dying over the following year compared with those who remained uninfected (aHR 3·1, 95%CI 2·9-3·3).
