The temperature reading depends on which part of the body is being measured. The typical daytime temperatures among healthy adults are as follows: Temperature in the rectum (rectal), vagina, or in the ear (tympanic) is about 37.5 °C (99.5 °F) [20] [medical citation needed] Temperature in the mouth (oral) is about 36.8 °C (98.2 °F) [12]
[13] [15] It differs from hyperthermia, in that hyperthermia is an increase in body temperature over the temperature set point, due to either too much heat production or not enough heat loss. [1] Treatment to reduce fever is generally not required. [2] [9] Treatment of associated pain and inflammation, however, may be useful and help a person ...
The symptoms of pneumonia are fever, productive cough, shortness of breath, and pleuritic chest pain. [2] Inspiratory crackles may be heard on exam. [2] A chest x-ray can be useful to differentiate pneumonia from congestive heart failure. [2] As the cause is usually a bacterial infection, antibiotics are typically used for treatment. [2]
Chronic diseases constitute a major cause of mortality, and the World Health Organization (WHO) attributes 38 million deaths a year to non-communicable diseases. [5] In the United States approximately 40% of adults have at least two chronic conditions. [6] [7] Having more than one chronic condition is referred to as multimorbidity. [8]
In 3–4% of cases (7.4% for those over age 65) symptoms are severe enough to cause hospitalisation. [153] Mild cases typically recover within two weeks, while those with severe or critical diseases may take three to six weeks to recover. Among those who have died, the time from symptom onset to death has ranged from two to eight weeks.
In 1920, the mortality rate among people under 65 had decreased sixfold to half the mortality rate of people over 65, but 92% of deaths still occurred in people under 65. [300] This is unusual since influenza is typically most deadly to weak individuals, such as infants under age two, adults over age 70, and the immunocompromised .
That study also found that most of these differences in IFR reflected corresponding differences in the age composition of the population and age-specific infection rates; in particular, the metaregression estimate of IFR is very low for children and younger adults (e.g., 0.002% at age 10 and 0.01% at age 25) but increases progressively to 0.4% ...
[237] A 2011 study concluded that traffic exhaust is the single most serious preventable cause of heart attack in the general public, the cause of 7.4% of all attacks. [ 238 ] Particulate matter studies in Bangkok, Thailand from 2008 indicated a 1.9% increased risk of dying from cardiovascular disease, and 1.0% risk of all disease for every 10 ...
