### what you need to know since the emergence of sars-cov-2 in december 2019, there has been an unparalleled global effort to characterise the virus and the clinical course of disease. Coronavirus disease 2019 (covid-19), caused by sars-cov-2, follows a biphasic pattern of illness that likely results from the combination of an early viral response phase and an inflammatory second phase.

As infection subsides, the epithelium is regenerated, a process that can take up to a month.
Viral pathogenesis involves several steps that must occur for the virus to infect and cause disease in the host: virus entry into the host, primary virus replication, virus spread within the host, infection of cells with special affinities for the virus (cell tropism), cellular injury, host immune response, viral clearance or persistence, and viral shedding and transmission.

Sepsis can be caused by a broad range of pathogens; however, bacterial infections represent the majority of sepsis cases. Up to 42% of sepsis presentations are culture negative, suggesting a non-bacterial cause.
Many cytokines have known roles in the pathogenesis of rsv bronchiolitis, and some are even implicated in sustaining the infection.
