High altitude reduces infection rate of COVID-19 but not case-fatality rate

Disease Associated with Equine Coronavirus Infection and High Case Fatality Rate

BACKGROUND Equine coronavirus (ECoV) is associated with clinical disease in adult horses. Outbreaks are associated with a low case fatality rate and a small number of animals with signs of encephalopathic disease are described. OBJECTIVES The aim of this study is to describe the epidemiological and clinical features of two outbreaks of ECoV infection that were associated with an high case fat...

On case-fatality rate: review and hypothesis.

The relationship between log cumulative number of patients (X) and that of deaths (Y) in an epidemic follows the equation logY = klogX - klogN(0), where k is a constant determining the slope and N(0) is the value of X when Y = 1. Diseases with k = 1 are Ebola hemorrhagic fever, avian influenza H5N1, cholera, and hand, foot, and mouth disease; those with k > 1 are the influenza H1N1 2009 pand...

Unravelling the Pathogenesis of Severe COVID-19 Pneumonia: Are There Possible Insights From High Altitude?

Case fatality rate of severe acute respiratory syndromes in Beijing.

OBJECTIVE To describe the case fatality rate of SARS in Beijing. METHODS Data of SARS cases notified from Beijing Center for Disease Control and Prevention (BCDC) and supplemented by other channels were collected. The data were analyzed by rate calculation. RESULTS The case fatality rate of SARS in Beijing was 7.66%, and had an ascending trend while the age of cases was getting older, and a...

Factor influencing case-fatality rate of septicemic children.

One hundred and fourty episodes of septicemic children seen at Songklanagarind Hospital during a period of two years were reviewed to determine factors related to mortality. One hundred episodes (70.4%) of septicemia were hospital-acquired in which 98 (69%) were caused by gram negative bacilli, with Pseudomonas being the most common agent. Thirty episodes were from gram-positive cocci and eight...
