Endemic (epidemiology) Human alphaherpesvirus 3 virion − a herpesvirus known to infect humans. It causes chickenpox (varicella), a disease most commonly affecting children, teens, and young adults, and shingles (herpes zoster) in adults. In epidemiology, an infection is said to be endemic in a specific population or populated place when that ...
Endemic is a frequently misunderstood and misused word outside the realm of epidemiology. Endemic does not mean mild, or that COVID-19 must become a less hazardous disease. The severity of endemic disease would be dependent on various factors, including the evolution of the virus, population immunity, and vaccine development and rollout. [2] [4 ...
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 ...
Clade I is endemic in central Africa, while clade II is endemic in West Africa. A new variant of clade I, called Ib, appears to spread more easily. ... The disease usually passes to humans from ...
Epstein–Barr virus infectious mononucleosis (Mono) Fever – usually lasting 14 days; often mild. Sore throat – usually severe for 3–5 days, before resolving in the next 7–10 days. Swollen glands – mobile; usually located around the back of the neck (posterior cervical lymph nodes) and sometimes throughout the body.
An endemic disease is one with a continuous occurrence at an expected frequency over a certain period of time and in a certain geographical location. Two terms are used when the degree of transmission or infection of an endemic disease is high: hyperendemic and holoendemic .
Influenza is an endemic disease, with a fairly constant number of cases which vary seasonally and can, to a certain extent, be predicted. [127] In a typical year, 5–15% of the population contracts influenza. There are 3–5 million severe cases annually, with up to 650,000 respiratory-related deaths globally each year. [128]
Holoendemic. A disease is holoendemic when essentially every individual in a population is infected. [1] [2] Although the infection is ubiquitous, symptoms of disease do not appear equally across age groups. The young are more likely to express pathogenic responses, whilst the older hosts will carry the disease asymptomatically, or with reduced ...
