This is a great question, an area of active debate, and a personal interest of mine. I actually just did a presentation on this, so this answer will probably have more information in it than you need, but I'll add it for completeness. Fever as an Adaptive Response The first important thing to know about fever is that it is something your body initiates ...

Fever can be a result of many processes. In context of infectious diseases, the fever is triggered by substances released by the immune cells (substances such as interleukin-1 and -6). Also, pyrexia can be achieved by getting exogenous pyrogens, substances from the bacterial debris that can create the same response. Those substances then interact with one ...

Is there any evidence that taking a bath or shower when sick has negative effects? This is quite interesting because I've heard MANY patients with this same belief. Some people believe that bathing when sick will make you more sick. Some women do not bathe during their menstrual period because their mothers told them it would lead to some adverse effects. ...

Common cold, which is an acute viral infection of the nose, is rarely associated with fever in adults (Canadian Medical Association Journal ; DPHHS Montana). Allergic rhinitis does not usually cause fever; it's not mentioned as a symptoms on major clinical websites (Emedicine ; Mayo Clinic ; MedlinePlus). News In Health says allergic rhinitis "never" causes ...

I could find one letter to the editor from 2011 that posits a few mechanisms by which increased blood flow caused by the fever might make autism symptoms better: Does fever relieve autistic behavior by improving brain blood flow?. It also mentions a workshop on the topic that happened in 2010. Here is the workshop report. One clear conclusion from the ...

In "A Journal of the Plague Year", Daniel Defoe writes of a febrile patient who cures himself of the plague by swimming in a river: I heard of one infected creature who, running out of his bed in his shirt in the anguish and agony of his swellings, of which he had three upon him, got his shoes on and went to put on his coat; but the nurse resisting, and ...

Altogether, digital thermometers are known to be very inaccurate.2. If you want the most accurate reading, a fever should be measured rectally, not axillary (in the armpit)1. So therefore, different limits apply to axillary temperature measurements: In patients older than 1 month, the mean difference (SD) between the rectal and axillary temperatures was 1....

There are differences between individual clinicians' ways of approaching things, and regional ones as well, so I can't speak for every clinician. But respiratory infections are one of the most common reasons why someone comes into primary care or urgent care, and there are common approaches. When someone comes in with cold symptoms, many factors that are ...

FEVER There is still no final agreement among experts about the treatment of fever, but recently some of them lean toward not treating it unless it's life-threatening. Fever: suppress or let it ride? (PubMed, 2015): There are two basic fields of thought: (I) fever should be suppressed because its metabolic costs outweigh its potential physiologic ...

In normal patients fever can reduce our efficiency or comfort for doing work. For mild infections one may wait for the fever to get over and let our immune response do their job. For early and effective treatment we prefer antibiotics with antipyretics as antibiotics can do their job alone and fever might not be necessary here. It will give early response ...

As you have already described, the hypothalamus regulate the set point at which the body temperature is maintained. This set point is elevated in fever, reflecting an infection, or resulting from tissue damage, inflammation, etc. These conditions all enhance formation of cytokines such as IL-1beta, IL-6, TNF-alfa, and interferons, which act as endogenous ...

Examples of conditions with fever and severe headache in which inflammation is not involved or is not the main process: Caffeine overdose (BMJ) "Thyroid storm" - acute hyperthyropidism (PubMed) Hyperparathyroidism, for example, due to adenoma of parathyroid glands (Annals.org) Cancers and tumors, such as lymphoma, brain tumors, pituitary adenoma (Cancer.net)...

There are studies that state reducing a fever may prolong illness. Fever can increase T-cell proliferation and cytotoxic activity. A study in 1990 showed that acetaminophen and aspirin increased symptoms and made viral shedding last longer. While that doesn't exactly address the role of NSAIDS I would think it would be the same as aspirin and acetaminophen. ...

Saliva is the main route of exposure, so kissing, sharing utensils, etc. should be avoided. Casual contact such as handshaking and sitting near them aren't much of a risk unless they're coughing or sneezing on you. http://www.nhs.uk/conditions/Glandular-fever/Pages/Introduction.aspx This virus is found in the saliva of infected people and can be spread ...
