The two most common causes of death in the UK are diseases of the circulatory system (including strokes and heart disease) and cancer.
Overall annual death rates among women in the UK at the start of the 21st century were
7.98 per 1,000 population, and among men,
5.58 per 1,000. Comparable ?gures at the start of the 20th century were 16.3 for women and
18.4 for men. The death rates in 1900 among infants up to the age of four were 47.9 per 1,000 females and 57 per 1,000 males. By 2003 these numbers had fallen to 5.0 and 5.8 respectively. All these ?gures give a crude indication of how the health of Britain’s population has improved in the past century.
Death rates and ?gures on the causes of deaths are essential statistics in the study of EPIDEMIOLOGY which, along with information on the incidence of illnesses and injuries, provides a temporal and geographical map of changing health patterns in communities. Such information is valuable in planning preventive health measures (see PUBLIC HEALTH) and in identifying the natural history of diseases – knowledge that often contributes to the development of preventive measures and treatments for those diseases....

The loss of keenness in taste brought about by a cold in the head, or even by holding the nose while swallowing, is well known. Sweet tastes seem to be best appreciated by the tip of the tongue, acids on its edges, and bitters at the back. There are probably di?erent nerve-?bres and end-organs for the di?erent varieties of taste. Many tastes depend upon the ordinary sensations of the tongue.
Like other sensations, taste can be very highly educated for a time, as in tea-tasters and wine-tasters, but this special adaptation is lost after some years.... Medical Dictionary
3. Myxoviruses, which are one of a group of RNA-containing viruses, have an a?nity for protein receptors in red blood cells.... Medical Dictionary
A single virus particle (virion) consists of an inner core of nucleic acid, which may be either DNA or RNA, surrounded
by 1 or 2 protective protein shells (capsids). Surrounding the outer capsid may be another layer, the viral envelope, which consists mainly of protein. The nucleic acid consists of a string of genes that contain coded instructions for making copies of the virus.
Common viral diseases include the common cold, influenza, and chickenpox (caused by the varicella–zoster virus). AIDS is caused by the human immunodeficiency virus (HIV).... BMA Medical Dictionary
