Since opportunistic infections can cause severe disease, much emphasis is placed on measures to prevent infection. Such a strategy usually includes restoration of the immune system as soon as possible, avoiding exposures to infectious agents, and using antimicrobial medications ("prophylactic medications") directed against specific infections.
Additionally, people with AIDS often have systemic symptoms of infection like fevers, sweats (particularly at night), swollen glands, chills, weakness, and weight loss. [13] [14] The specific opportunistic infections that AIDS patients develop depend in part on the prevalence of these infections in the geographic area in which the patient lives.
Most of these conditions are opportunistic infections that are easily treated in healthy people. The staging system is different for adults and adolescents and children. [2] Stage I: HIV disease is asymptomatic and not categorized as AIDS. Stage II: include minor mucocutaneous manifestations and recurrent upper respiratory tract infections.
Opportunistic infections may be caused by bacteria, viruses, fungi, and parasites that are normally controlled by the immune system. [39] Which infections occur depends partly on what organisms are common in the person's environment. [32] These infections may affect nearly every organ system. [40]
Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.
Bacterial infection; Typical symptoms In general, viral infections are systemic. This means they involve many different parts of the body or more than one body system at the same time; i.e. a runny nose, sinus congestion, cough, body aches etc. They can be local at times as in viral conjunctivitis or "pink eye" and herpes.
Esophageal candidiasis is an opportunistic infection of the esophagus by Candida albicans. The disease usually occurs in patients in immunocompromised states, including post-chemotherapy and in AIDS. However, it can also occur in patients with no predisposing risk factors, and is more likely to be asymptomatic in those patients. [1]
Several reports of infections these bacteria cause are correlated with patients who have AIDS. [6] P. oryzihabitans is increasingly identified as a cause of opportunistic infections, taking advantage of weak immune systems in people. However, it is rare for the infection to escalate into sepsis, but there have been cases where patients have ...
