COVID-19
Basics
Transmission
- Children can carry the virus in their noses for weeks
- ECDC back to school guidelines
- Huge list of papers on mask efficacy
- SARS-CoV-2 Transmission Dynamics Should Inform Policy
- It’s Time to Talk About Covid-19 and Surfaces Again
- Aerosol transmission of Covid-19: A room, a bar and a classroom: how the coronavirus is spread through the air
- Aerosol vs droplets (It's aerosol all the way.)
- You can catch COVID a second time, even when fully vaccinated.
- CDC stury finds that the transmission risk is 3.5x higher in schools without mask requirements
- 2022-10-11 5 days after symptom onset, 80% test still positive
Variants
Tests
Von den 2215 Studienteilnehmern wurde bei 338 Personen eine SARS-CoV-2-Infektion durch rRT-PCR-Test nachgewiesen. Wurden die Proben dieser Virusträger mit dem Roche-Test analysiert, zeigten nur 204 Proben ein positives Resultat. Mit dem Abbott-Test waren hingegen nur 192 der Proben positiv. Das entspricht einer Sensitivität über alle Probandengruppen von 60,4 Prozent für den Roche-Test und 56,8 Prozent für den Abbott-Test. Daraus lässt sich ableiten, dass von zehn mit einem PCR-Tests positiv getesteten Personen rund vier nicht mit einem Antigen-Schnelltest erkannt werden.
Health impact
Physical health
- 2022-06-22 Each SARS-CoV-2 reinfection causes more severe disease
- 2025-02-26 Long-term clinical outcome and exercise capacity in SARS-CoV-2-positive elite athletes: "The SARS-CoV‑2 prevalence was nearly identical in noncontact and contact-sport athletes (10.8% vs. 11.3%); 37% experienced symptoms lasting > 4 weeks. Over 50% of athletes paused their training for 4–8 weeks. At t1, 40% still experienced reduced perceived performance capacity (PPC) compared to their pre-COVID-19 level, while 64% reported ongoing limitations in sports participation, with mental and physical fatigue as the most prominent limiting factor, followed by shortness of breath and joint and muscle pain."
