Recurrent infection

Introduction Medical infection refers to local tissue and systemic inflammatory reactions caused by the invasion of pathogens such as bacteria, viruses, fungi, and parasites into the human body. Repeated infection refers to repeated frequent infections. There are many causes of repeated infections, including non-immune factors (such as skin mucosal barrier damage) and immune causes. Defects in leukocyte activity, thymus-derived immunoreactive cytopathic, impaired inflammatory response, insufficient complement function and insufficient opsonin, gamma globulin deficiency, splenectomy. In addition, the discharge of secretions, the presence of infectious agents in the family or elsewhere can cause repeated infections.

Cause

Mostly congenital factors or low body immune function or lack of trace elements and vitamins, or improper feeding methods, as well as genetic, nursing, living environment and other factors, if not treated properly can lead to asthma, myocarditis, nephritis and other diseases Defects in leukocyte activity, thymus-derived immunoreactive cytopathic, impaired inflammatory response, insufficient complement function and insufficient opsonin, gamma globulin deficiency, splenectomy. In addition, the discharge of secretions, the presence of infectious agents in the family or elsewhere can cause repeated infections.

1. Blood examination: It can be judged that it is a viral infection, a bacterial infection, and the cause is determined.

2. Bacterial culture: Identify the pathogen of the infection and provide an important reference for the selection of therapeutic drugs.

3. Immunological examination, as well as trace element examination, blood biochemical examination, X-ray examination, B-ultrasound examination, urine examination, etc. to determine the infected lesions, according to the situation targeted treatment.

Differential diagnosis

Differential diagnosis of repeated infections:

1. Bacterial infection: bacterial infection is an acute systemic infection caused by pathogenic bacteria or conditional pathogens invading the blood circulation, producing toxins and other metabolites, clinically with chills, fever, rash, joint pain and liver and spleen. Swelling is characteristic, and some may have septic shock and migratory lesions. An acute systemic infection caused by a pathogenic microorganism invading the blood from a wound or an infected lesion in the body. Clinically, some patients may also have irritability, cold limbs and purpura, rapid pulse rate, rapid breathing, and decreased blood pressure. Especially in the elderly, children, those with chronic diseases or immunocompromised, those who are not treated promptly and have complications, can develop sepsis or sepsis.

2, viral infection: viral infection is an extremely complicated process, the infection is diverse, the results vary, the virus belongs to the subcellular structure, only its own nucleic acid and other necessary minimal structure. Viral infections can be divided into proliferative and non-proliferative infections.

3, fungal infection: the disease caused by fungal infection is called fungal disease, the highest incidence of candidiasis and dermatophytosis caused by the fungus of the normal flora of the human body, infection can be divided into: surface infection, skin infection, subcutaneous tissue infection , deep infections and conditional infections.

4. Parasitic infections: Parasitic infections are common in Africa, Asia and Central, South America, and rare in other regions. Travelers from industrialized to epidemic areas can often reduce the risk of infection by adhering to dietary and swimming hygiene guidelines and taking simple measures to reduce exposure. Tourists from endemic countries are sometimes less likely to transmit parasitic diseases in developed countries, as industrialized countries usually do not have many of the environmental conditions, media and intermediate hosts required for the spread of parasitic diseases. However, transmission of imported infections may still occur through fecal-oral routes, blood transfusions, organ transplants, or local appropriate media.
