The most commonly recognized behavioral patterns of animals and people at the onset of febrile infectious diseases are lethargy, depression, anorexia, and reduction in grooming. Findings from recent lines of research are reviewed to formulate the perspective that the behavior of sick animals and people is not a maladaptive response or the effect of debilitation, but rather an organized, evolved behavioral strategy to facilitate the role of fever in combating viral and bacterial infections. The… Expand

Dogs and cats that are ill with febrile diseases usually are depressed and anorexic. When viewed from the standpoint of the wild ancestors, it is apparent that the behavior of sick animals isExpand
Beyond Fever: Comparative Perspectives on Sickness Behavior
A wild animal, sick with a fever from an infectious disease, typically shows behavioral signs referred to as sickness behavior. The fever is advantageous because it inhibits the growth of pathogensExpand
The Legacy of Sickness Behaviors
TLDR
The legacy of 30 years of research in sickness behaviors is that it established the physiologic importance of reciprocal communication systems between the immune system and the brain. Expand
Sickness Behavior in Animals: Implications for Health and Wellness
TLDR
In husbandry of animals that are pets, farm animals or in zoos, markers of sickness behavior are indications of infection, or stress and impaired welfare. Expand
Mechanisms of the behavioural effects of cytokines.
TLDR
There is now clear evidence showing that sickness behaviour is not the result of weakness and physical debilitation affecting the sick individual, but the expression of a central motivational state that reorganizes the organism’s priorities to cope with pathogenic microorganisms. Expand
Sickness behavior in fever and hypothermia.
TLDR
An attempt has been made to find some biological logic in the appearance of various components of sickness behavior and changes in body temperature that could explain the purported positive value of sickness behavioral and thermoregulatory aspects in disease survival. Expand
Sickness Behavior: A Neuroimmune-Based Response to Infectious Disease
TLDR
The existence of a brain cytokine compartment that is inducible by peripheral immune stimuli and is associated with sickness behavior has important pathophysiological implications. Expand
Primate Self-medication and the Treatment of Parasite Infection
TLDR
Of any species studied thus far, chimpanzees have provided the most details for level 2 and 3 behaviors, exemplified by such behaviors as bitter pith chewing and whole leaf swallowing behaviors, used in response to parasite infection. Expand
Sickness behaviours in ducks include anorexia but not lethargy
TLDR
From the results it is clear that sickness-induced lethargy cannot be considered a clinical sign or a diagnostic criterion for the onset of pathogenic infection in certain lines of poultry. Expand
How Does the Social Grouping of Animals in Nature Protect Against Sickness? A Perspective
TLDR
A more general awareness and consideration of the possibilities that avoiding or adapting to sickness behavior may be driving some social behaviors of animals in nature is needed. Expand

This article brings together several lines of current research about depression, appetite control, and the role of fever in facilitating an animal's ability to combat viral and bacterial infections. Expand

TLDR
This approach should lead to improved medical treatment because preferred treatment depends on assessment of the validity of the three explanations, and its consequences for therapy are analyzed for fever, rhinorrhea and diarrhea. Expand
Fever: effect of drug-induced antipyresis on survival.
TLDR
To determine whether the prevention of fever affects the survival of an animal infected with pathogenic bacteria, lizards were infected with live Aeromonas hydrophila and received varying doses of sodium salicylate, an antipyretic drug. Expand
Temperature as a factor in resistance of young puppies to canine herpesvirus.
TLDR
Adult mice are more resistant to herpes simplex virus than younger animals, except when inoculated by the intracerebral route, and similar observations have been made for other animal species naturally infected with herpesviruses, including canine. Expand
Fever and survival
TLDR
An elevation in temperature following experimental bacterial infection results in a significant increase in host survival, as measured by survival. Expand

TLDR
Inflammatory tissue reactions as observed histologically are more obviously related to resistance and are generally considered to be especially important in localization and destruction of invading bacteria. Expand

TLDR
The development of large populations of lice on mice disabled by amputation of both rear limbs indicates that this paralytic sequel of rabies had a marked effect on the degree of parasitism. Expand

TLDR
Experimental studies on the pathogenesis of fever during the last 30 years suggest that fever and certain aspects of both immunoregulation and inflammation are produced by a single hormone, the monokine interleukin-1, which has presumably been selected by evolution to protect the host against infection.

Survival value of fever in fish
TLDR
It is reported here that fever significantly enhances survival of goldfish, Carassius auratus, at febrile temperatures about 10 °C lower than those of D. dorsails, after injection with live A. hydrophila. Expand

TLDR
Although the neuroendocrine cold defense responses that are stimulated in fever enhance the defenses of the host, the increase in temperature harms these defenses, and the resulting increase in aerobic capacity may not be necessary for an effective defense. Expand
