Signs and symptoms usually begin 12–72 hours after contracting the infectious agent. [15] If due to a virus, the condition usually resolves within one week. [ 18 ] Some viral infections also involve fever , fatigue, headache and muscle pain . [ 18 ]
An early morning temperature higher than 37.3 °C (99.1 °F) or a late afternoon temperature higher than 37.7 °C (99.9 °F) is normally considered a fever, assuming that the temperature is elevated due to a change in the hypothalamus's setpoint. [15] Lower thresholds are sometimes appropriate for elderly people. [15]
In unvaccinated adults, 16% get symptoms similar to the flu, while about 10% of vaccinated adults do. [87] Vaccination decreased confirmed cases of influenza from about 2.4% to 1.1%. [87] No effect on hospitalization was found. [87]
Veterinary oncology, concentrating mainly on cats and dogs, is a growing specialty in wealthy countries and the major forms of human treatment such as surgery and radiotherapy may be offered. The most common types of cancer differ, but the cancer burden seems at least as high in pets as in humans.
The treatment of moderately high arterial blood pressure (defined as >160/100 mmHg) with medications is associated with an improved life expectancy. [15] The effect of treatment of blood pressure between 130/80 mmHg and 160/100 mmHg is less clear, with some reviews finding benefit [ 6 ] [ 16 ] [ 17 ] [ 18 ] and others finding unclear benefit.

[39] Researchers in neurology and genetics discover the toxicity beta amyloid, a protein that accumulates in the brains of people with Alzheimer's disease, to neurons in 1989. This discovery indicates beta amyloid as the possible cause of the degenerative ...
