Immigrants to Denmark hospitalised with COVID-19 appear less likely to die than Danish-born residents

Nationwide study of all adults hospitalised with COVID-19 in Denmark between February 2020 and March 2021 finds that foreign-born adults were at markedly lower risk of dying from COVID-19 compared to Danish-born adults

Long COVID associated with different clinical trajectories and characteristics depending on severity of initial SARS-CoV-2 infection

Preliminary results from a study of over 205,000 Swedish adults with COVID-19 finds over a third of ICU patients were diagnosed with long COVID, compared to 6% of those hospitalised, and 1% of those not requiring hospitalisation.

Women were more than twice as likely to be diagnosed with long COVID compared to men among individuals with milder forms of initial infection—a weaker link was found among hospitalized but not ICU-treated individuals.

A history of mental illness or asthma was associated with twice the risk of being diagnosed with long COVID in people with initially mild COVID-19, but was less pronounced among hospitalised patients.

Study of all fully vaccinated people in Belgium assesses risk of breakthrough COVID-19 infections

A study of all fully vaccinated people in Belgium has assessed the risk factors associated with developing COVID-19 after vaccination. The research, which is being presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Lisbon, Portugal, (23-26 April) and published in the journal Viruses, found that breakthrough infections were more common in those who had received viral vector vaccines than mRNA vaccines. Those who had previously had Covid had a lower risk of breakthrough infections.

US study in over 850,000 patients hospitalised with COVID-19 underscores need for improvement in therapeutic approaches for critically ill

Report provides real-world treatment and outcome data for 850,000 US adults hospitalised with COVID-19 over 20 months of the pandemic (from May 2020 to December 2021 - a month after the Omicron variant was detected).

Findings suggest that the use of combination treatments increased over time, while average (median) hospital stay shortened (7 to 6 days) and ICU stays remained the same (5 days), while ICU use declined from 34% to 27%.

All-cause mortality rates remained unchanged at 16%, and survival improved for all levels of disease severity except for patients on invasive mechanical ventilation/ECMO whose mortality rate increased from 48% to 59%.

Even partially vaccinated individuals hospitalised with COVID-19 may be at lower risk of ICU admission and death than unvaccinated patients

Pregnant women with COVID-19 face greater risk of hospitalisation and ICU admission, strengthening case for vaccination

Canadian study compares the severity of COVID-19 in more than 2,200 pregnant women and over 11,200 non-pregnant women of child-bearing age, infected with SARS-CoV-2 at the same time.

Findings suggest women with COVID-19 during pregnancy are five times more likely to be hospitalised, and six times as likely to require treatment in intensive care.

Importantly, vaccination markedly reduced the risk of COVID-19 hospitalisation and ICU admission in all women, both pregnant and non-pregnant.

UK study of more than 2,000 patients after hospitalisation with COVID-19 shows only around 1 in 4 feel fully recovered after one year

Study highlights the lack of treatments for long COVID and likely enormous burden of this ever-growing cohort of patients

Population-wide study of COVID-19 vaccination shows that mix-and-match approach to booster vaccination offers the best protection

A new study on Chile’s national COVID-19 vaccination program, to be presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Global Health, shows that giving a different type of vaccine (heterologous) for the third or ‘booster’ dose than was received for the first two doses, leads to better vaccine performance than using the same (homologous) inactivated SARS-CoV-2 vaccine for all three doses.

Emerging MRSA strain with high potential for spread in the community has been isolated from hedgehogs in Helsinki.
The studied hedgehogs were also found to carry twice the prevalence of antibiotic-resistant ESBL-producing bacteria as human and companion animals in Finland – suggesting that they may be at increased risk of both acquiring and spreading these resistant bugs.

Global study finds increase in deaths from COVID-19 at the weekend

Worldwide analysis of nearly 6 million deaths from COVID-19 over 2 years finds an increase in COVID-19 mortality at weekends compared to weekdays.

Findings are unlikely to reflect just bureaucratic and reporting delays but also shortfalls in hospital capacity, clinical staffing and expertise, researchers say.

Among ten countries with the highest COVID-19 counts, the USA, Brazil, and the UK had significantly higher deaths on Saturday and Sunday compared to weekdays throughout the pandemic.

This “weekend effect” was not seen in Germany, where more COVID-related deaths were reported on weekdays.

Findings suggest Bolsonaro’s denialist attitude to COVID-19 left much of the country vulnerable to COVID-19, leading to unnecessary deaths.
