A disease cluster is an unusually large aggregation of a relatively uncommon disease (medical condition) or event within a particular geographical location or period. [1] Recognition of a cluster depends on its size being greater than would be expected by chance . [ 1 ]
Difference between outbreak, endemic, epidemic and pandemic. In epidemiology, an outbreak is a sudden increase in occurrences of a disease when cases are in excess of normal expectancy for the location or season. It may affect a small and localized group or impact upon thousands of people across an entire continent.
Disease clusters, or spatial groupings of proximity and characteristically related epidemics. While the term itself is relatively poorly defined, it generally “implies an excess of cases above some background rate bounded in time and space.” [ 1 ] Although clustering is not the most precise method for spatial analysis, it can and has proved ...
The cluster of cases in Ohio are not caused by a new virus, officials say, but rather the typical gamut of germs that cause pneumonia in kids and adults every year, including influenza ...
Outbreak response or outbreak control measures are acts which attempt to minimize the spread of or effects of a disease outbreak.Outbreak response includes aspects of general disease control such as maintaining adequate hygiene, but may also include responses that extend beyond traditional healthcare settings and are unique to an outbreak, such as physical distancing, contact tracing, mapping ...
Health authorities around the world are still grappling with lessons learned at the start of the Covid-19 pandemic and trying to determine the best way to prevent a new one.. Many researchers have ...
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
An epidemic curve, also known as an epi curve or epidemiological curve, is a statistical chart used in epidemiology to visualise the onset of a disease outbreak. It can help with the identification of the mode of transmission of the disease. It can also show the disease's magnitude, whether cases are clustered or if there are individual case ...
