COVID-19

Der Omikron-Subtyp BA.5 breitet sich weiter aus. Doch welche neuen und bekannten Symptome deuten auf eine Infektion mit der Corona-Variante hin?

Anosmia, or the loss of the sense of smell caused by long COVID is linked to changes in the brain that prevents correct olfactory processing.

Too much coverage minimizes the health risks researchers attribute to the virus

Die Infektionszahlen sinken, in Deutschland sind die letzten Schutzmaßnahmen ausgelaufen, offiziell sind sie nicht mehr nötig. Aber stimmt das?

Amsterdam, April 4, 2023 – Infection with SARS-CoV-2 has a significant impact on cognitive function in patients with preexisting dementia, according to new research, published in the Journal of Alzheimer's Disease Reports. Patients with all subtypes of dementia included in the study experienced rapidly progressive dementia following infection with SARS-CoV-2.

Advocates ask the US biomedical agency to rethink the design of its RECOVER initiative, citing possible harm and funding waste.

Although people with severe COVID had highest risk, mild cases also upped risks.

A recent review from a prominent scientific source has reignited the debate over masks.

The latest data from the Office for National Statistics suggests that more than 1.2 million people in the U.K. report living with long COVID for 12 months or more.

Eine groß angelegte Studie findet keinen Beleg dafür, dass Masken die Verbreitung von Corona gebremst haben. Doch die Schlüsse, die die Forscher ziehen, sind fragwürdig.

Das BfArM hat in Abstimmung mit dem Bundesministerium für Gesundheit wichtige Informationen zu den Anti-COVID-19 Arzneimitteln Paxlovid® (Nirmatrelvir (PF-07321332) + Ritonavir) und Lagevrio® (Molnupiravir) zusammengestellt.

While there are still far more questions than answers about long COVID-19, researchers are beginning to get a clearer picture of the health and economic consequences of the condition.

3 patients in last 2 weeks all with significant short term memory issues including forgetting where they are going while driving. No prior dementia. None brought up COVID infection until asked.

Background: There is limited information on the role of different age groups in propagating SARSCoV2 epidemics driven by the Omicron variants. Methods: We examined the role of individuals in different age groups in propagating the Spring, Summer, and Autumn waves of the Omicron epidemics in France using the previously developed methodology based on the relative risk (RR) statistic that measures the change in the proportion of an age group among all cases admitted to ICU for COVID19 before vs. after the peak of an epidemic wave. Higher value of the RR statistic for a given age group suggests a disproportionate depletion of susceptible individuals in that age group during the ascent of the epidemic (due to increased contact rates and/or susceptibility to infection). Results: For the Spring wave (March 14 through May 15), the highest RR estimate belonged to children aged 10 to 19y (RR=1.92 (95% CI (1.18,3.12)), followed by adults aged 40 to 49y (RR=1.45 (1.09,1.93)) and children aged 0 to 9y (RR=1.31 (0.98,1.74)). For the Summer wave (June 27 through Aug. 21), the highest RR estimate belonged to children aged 0 to 9y (RR=1.61 (1.12,2.3)) followed by children aged 10 to 19y (RR=1.46 (0.72,2.93)) and adults aged 20 to 29y (RR=1.42 (0.91,2.23)). For the Autumn wave (Sep. 18 through Nov. 12), the highest RR estimate belonged to children aged 10 to 19y (RR=1.63 (0.72,3.71)), followed by adults aged 30 to 34y (RR=1.34 (0.8,2.25)) and 20 to 24y (RR=1.20 (0.65,2.21)). Conclusions: Children aged 10 to 19y played the greatest relative role in propagating Omicron epidemics, particularly when schools were open, followed by children aged 0 to 9y and adults aged 20 to 29y, as well as adults aged 30 to 49y. Persons aged over 50y played a more limited role in propagating Omicron infection in the community. Additional efforts are needed to increase vaccination coverage in children aged 10 to 19y, as well as younger children and young adults to mitigate Omicron epidemics in the community. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study did not receive any funding ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Background Long Covid is an emerging chronic illness potentially affecting millions, sometimes preventing the ability to work or participate in normal daily activities. COVID-OUT was an investigator-initiated, multi-site, phase 3, randomized, quadruple-blinded placebo-controlled clinical trial ([NCT04510194][1]). The design simultaneously assessed three oral medications (metformin, ivermectin, fluvoxamine) using two by three parallel treatment factorial assignment to efficiently share placebo controls and assessed Long Covid outcomes for 10 months to understand whether early outpatient treatment of SARS-CoV-2 with metformin, ivermectin, or fluvoxamine prevents Long Covid. Methods: This was a decentralized, remotely delivered trial in the US of 1,125 adults age 30 to 85 with overweight or obesity, fewer than 7 days of symptoms, and enrolled within three days of a documented SARS-CoV-2 infection. Immediate release metformin titrated over 6 days to 1,500mg per day 14 days total; ivermectin 430mcg/kg/day for 3 days; fluvoxamine, 50mg on day one then 50mg twice daily through 14 days. Medical-provider diagnosis of Long Covid, reported by participant by day 300 after randomization was a pre-specified secondary outcome; the primary outcome of the trial was severe Covid by day 14. Result: The median age was 45 years (IQR 37 to 54), 56% female of whom 7% were pregnant. Two percent identified as Native American; 3.7% as Asian; 7.4% as Black/African American; 82.8% as white; and 12.7% as Hispanic/Latino. The median BMI was 29.8 kg/m2 (IQR 27 to 34); 51% had a BMI 30kg/m2. Overall, 8.4% reported having received a diagnosis of Long Covid from a medical provider: 6.3% in the metformin group and 10.6% in the metformin control; 8.0% in the ivermectin group and 8.1% in the ivermectin control; and 10.1% in the fluvoxamine group and 7.5% in the fluvoxamine control. The Hazard Ratio (HR) for Long Covid in the metformin group versus control was 0.58 (95% CI 0.38 to 0.88); 0.99 (95% CI 0.592 to 1.643) in the ivermectin group; and 1.36 in the fluvoxamine group (95% CI 0.785 to 2.385). Conclusions: There was a 42% relative decrease in the incidence of Long Covid in the metformin group compared to its blinded control in a secondary outcome of this randomized phase 3 trial.

Bis heute herrscht die irrige Idee, Long Covid sei die normale Erholungsphase nach schwerer Krankheit. Studien belegen das Gegenteil. Ein Problem ist die babylonische Symptomverwirrung.
