COVID-19: Epidemiologische und klinische Fakten

Abstract: Zusammenfassung Bis zum 31.07.2020 wurden weltweit ca. 17,6 Mio. SARS-CoV-2-Infizierte und ca. 680.000 Todesfälle aufgrund von COVID-19 gemeldet. SARS-CoV‑2 wird über Tröpfchen und wahrscheinlich auch Aerosole übertragen. Die Infektiosität beginnt 2–3 Tage vor Symptombeginn, auch asymptomatisch Infizierte sind infektiös. Die Erkrankung betrifft die oberen Atemwege und die Lungen (Pneumonie, akutes Lungenversagen [ARDS]), ferner Herz, Leber, Magen-Darm-Trakt und andere Organe. Das Virus nutzt ACE2 als Rezeptor … Show more

“…Due to the need to optimize the diagnostic method to achieve a high specificity and sensitivity and to allow a greater number of infected people to be diagnosed more rapidly, this review compiled information that evaluated saliva as an alternative testing sample for the diagnosis of COVID-19. Reviewing the geographical distribution of the selected studies, we can observe that there was an equality between the number of cases globally and the number of publications per continent, being America (17.3 million), Asia (7.6 million), and Europe (6.4 million) among the locations with the largest number of confirmed cases around the world ( 2 ). It is interesting to note that the selected articles came from countries with a high level of scientific production, such as the United States, Japan, and China.…”

“…This virus rapidly spread worldwide ( 1 ). As of July 2020, it is estimated that there had been a total of 17.6 million confirmed cases and 680 thousand deaths from COVID-19 worldwide ( 2 ). SARS-CoV-2 mainly affects the upper respiratory tract, and its most common symptoms include fever, cough, dyspnea, and myalgia.…”

“…Die Sensitivität dieser Methode hängt u. a. von der Qualität des Abstrichs ab, aber auch von der Phase des Infektionsverlaufs. Wenn die Entzündung der oberen Atemwege abgeklungen ist, kann die RT-PCR aus dem Rachenabstrich falsch-negativ ausfallen, obwohl die Infektion sich zur gleichen Zeit bereits im unteren Atemtrakt manifestiert hat [ 6 , 7 ]. Sputum, aus dem sich Virus-RNA isolieren ließe, wird von einigen Patienten und Patientinnen nicht produziert.…”

“…La declaración de pandemia debido a la propagación global del covid-19 hecha por la Organización Mundial de la Salud (OMS en adelante) el día 11 de marzo del año 2020, motivó medidas como el distanciamiento social y el cierre de instituciones en gran número de naciones. Los cientos de millones de infectados y millones de fallecimientos debidos a este nuevo coronavirus en todos los continentes dan cuenta de su gran capacidad contagiosa, su alto poder patogénico y el elevado riesgo que representa el contacto físico entre las personas, que pueden fácilmente contraer la infección al inhalar o tocar partículas contaminadas generadas por la actividad respiratoria de un infectado (Hemmer et al, 2020;Wang et al, 2020;Singh et al, 2021). Estas características en conjunto, han determinado la migración de actividades habitualmente presenciales hacia modalidades virtuales, donde no sea necesaria la agrupación de los participantes, disminuyendo así el riesgo de contraer la enfermedad (Jayaweera et al, 2020;Kokubun & Yanakawa, 2021).…”
