Hygiene practices: washing hands frequently, covering mouth and nose while coughing or sneezing, and avoiding close contact with infected individuals can help prevent the spread of viral infections. Antiviral m
It commonly develops because of antigen persistence and is seen following many chronic viral infections. It is possible that persistent dermatophyte antigens, despite resolution of lesions, may have led to exhaustion of CLA+ T cells in these cases, eventually leading to the affected sites becoming...
During the later stages of HIV, the host is at high risk of developing meningitis, tuberculosis, and conditions associated with viral infections, e.g., Kaposi’s sarcoma. Thus, opportunistic pathogens represent a major cause of death in AIDS patients. Opportunistic pathogens are also a major ...
The emergence of antibiotic resistance is a product of human behavior. The more antibiotics are used, the more bacteria become resistant to them. For example, antibiotics are often prescribed for viral infections, in which they do not work. Livestock are treated with antibiotics to prevent infectio...
Still, people with a family history of autoimmune diseases are more likely to develop them — for example,multiple sclerosisruns in families. Some environmental factors such as pollutants, certain medications, viral infections and diet are also implicated in the manifestation of autoimmune diseases, ac...
The factors that act positively include, radiation, toxins, hypoxia, hyperthermia, viral infections, free radicals, among others. All of these factors cause changes in the inner mitochondrial membrane that causes the opening of the mitochondrial permeability transition (MPT) pore and release of two ...
There are four types of infections. The four types are bacterial, viral, fungal, parasitic infections. They are caused by bacterial, viruses, fungi, and parasites respectively. What is an infectious agent? Infectious agents can be defined as agents that cause infections or infectious diseases. Ex...

Acute illnesses include bacterial and viral infections, as well as sudden and short acting physical symptoms. Acute injuries tend to be straightforward; trauma, accidents, and violence typically are the cause of these cases. Read Acute Illness | Definition & Examples Lesson ...
In the field of biology, morphology is defined as the study of the structure and shape of parts of different organisms. Morphology of a virus studies the size, shapes, and forms of different viruses. The shape of the virion, that is, a complete viral particle outside a host cell, and ...
