[7] The COVID-19 pandemic ranks as the fifth-deadliest pandemic or epidemic in history.
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]
Basal body temperature (BBT or BTP) is the lowest body temperature attained during rest (usually during sleep). It is usually estimated by a temperature measurement immediately after awakening and before any physical activity has been undertaken. This will lead to a somewhat higher value than the true BBT.
The Earth's equator does not line up with the plane of the Earth's orbit, so for half of the year the Northern Hemisphere is tilted more towards the Sun and for the other half the Northern Hemisphere is tilted more away, causing seasonal temperature variation. Seasons are not caused by the Earth being closer to the Sun in the summer than in the ...
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [1] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [2]

The CDC has found that obesity is the single strongest risk factor for severe COVID-19 illness. [51] Complications are either directly caused by obesity or indirectly related through mechanisms sharing a common cause such as a poor diet or a sedentary lifestyle. The strength of the link between obesity and specific conditions varies.
