Transmission Of SARS-CoV-2
The transmission of COVID-19 is the Transmission (medicine), passing of coronavirus disease 2019 from person to person. COVID-19 is mainly transmitted when people breathe in air contaminated by Drop (liquid), droplets/aerosols and small Airborne transmission, airborne particles containing the virus. Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing. Transmission is more likely the more physically close people are. However, infection can occur over longer distances, particularly indoors. Infectivity can begin four to five days before the onset of symptoms, although contact tracing typically begins only two to three days before symptom onset. Infected people can spread the disease even if they are pre-symptomatic or asymptomatic. Most commonly, the peak viral load in upper respiratory tract samples occurs close to the time of symptom onset and declines after the first week after symptoms begin. Current evidence suggests a duration of viral sheddi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infection Prevention And Control
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe, infection prevention and control is expanded from healthcare into a component in public health, known as "infection protection" (''smittevern, smittskydd, Infektionsschutz'' in the local languages). It is an essential part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole. Infection control addresses factors related to the spread of infections within the healthcare setting, whether among patients, from patients to staff, from staff to patients, or among staff. This includes preventive healthcare, preventive measures such as hand washing, cleaning, disinfecting, Sterilization (microbiology), sterilizing, an ...
