Hace 3 días · A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications.Using advanced ...
Hace 3 días · Pandemics timeline death tolls. This is a list of the largest known epidemics and pandemics caused by an infectious disease in humans. Widespread non-communicable diseases such as cardiovascular disease and cancer are not included. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal infections, an attack ...
Hace 21 horas · Estimation of the SARS-CoV-2 incubation time distribution is hampered by incomplete data about infection. We discuss two biases that may result from incorrect handling of such data. Notified cases may recall recent exposures more precisely (differential recall). This creates bias if the analysis is restricted to observations with well-defined exposures, as longer incubation times are more ...
Hace 3 días · The most recent trend has focused on emerging and re-emerging viruses and our related preparedness and response aspects. However, human virology goes beyond (re)-emerging viral diseases. This section aims at addressing all aspects of human viruses, medical virology and virus-induced clinical diseases.
Hace 4 días · This site is intended for US healthcare professionals. Key Stages of the SARS-CoV-2 Life Cycle. SARS‑CoV‑2—the causative agent of COVID‑19—is a member of the highly diverse coronavirus family, named for the crown-like spikes present on their surface. 1-3 Like other members of this virus family, SARS‑CoV‑2 is an enveloped, positive-sense, single‑stranded RNA virus. 1
Hace 3 días · The social history of viruses describes the influence of viruses and viral infections on human history. Epidemics caused by viruses began when human behaviour changed during the Neolithic period, around 12,000 years ago, when humans developed more densely populated agricultural communities.
Hace 4 días · Influenza epidemics in modern times have the tendency to start in the eastern or southern hemisphere, with Asia being a key reservoir. Influenza A virus and influenza B virus co-circulate, so have the same patterns of transmission. The seasonality of influenza C virus, however, is poorly understood.
