Explain the ways an infective agent might enter the human body
Infection is the invasion of the body by any of various agents — including bacteria, fungi (see fungus), protozoans, viruses, and worms — and its reaction to them or their toxins. [ Infections are called subclinical until they perceptibly affect health, when they become infectious diseases. Infection can be local (e.g., an abscess), confined to one body system (e.g., pneumonia in the lungs), or
generalized (e.g., septicemia). Infectious agents can enter the body by inhalation, ingestion, sexual transmission, passage to a fetus during pregnancy or birth, wound contamination, animal bites, or insect bites. The body responds with an attack on the invader by leukocytes, production of antibodies or antitoxins, and often a rise in temperature. The antibodies may result in short-term or lifelong immunity. Despite significant progress in preventing and treating infectious diseases, they remain a major cause of illness and death, particularly in regions of poor sanitation, poor nutrition, and crowding.

User: Identify common sources of infection that might affect the human body

Weegy: iruses have different mechanisms by which they produce disease in an organism, which largely depends on the viral species. Mechanisms at the cellular level primarily include cell lysis, the breaking open and subsequent death of the cell. [ In multicellular organisms, if enough cells die, the whole organism will start to suffer the effects. Although viruses cause disruption of healthy homeostasis, resulting in disease, they may exist relatively harmlessly within an organism. An example would include the ability of the herpes simplex virus, which causes cold sores, to remain in a dormant state within the human body. This is called latency[127] and is a characteristic of the herpes viruses including Epstein-Barr virus, which causes glandular fever, and varicella zoster virus, which causes chickenpox and shingles. Most people have been infected with at least one of these types of herpes virus.[128] However, these latent viruses might sometimes be beneficial, as the presence of the virus can increase immunity against bacterial pathogens, such as Yersinia pestis.[129] Some viruses can cause life-long or chronic infections, where the viruses continue to replicate in the body despite the host's defence mechanisms.[130] This is common in hepatitis B virus and hepatitis C virus infections. People chronically infected are known as carriers, as they serve as reservoirs of infectious virus.[131] In populations with a high proportion of carriers, the disease is said to be endemic.[132] source: wikipedia ]

what methods of communication people with sight loss used
Weegy: Read a Deaf Blind Uk Site article: (Types of Communication People suffering from deafblindness use a variety of different communication methods. Which method they choose depends upon how much useful sight and hearing they retain. [ Other factors include the causes of their deafblindness and for how long the person has had sensory impairments. And in some cases a deafblind person can make use of a combination of techniques to communicate. Here are some of the most common types of communication used by deafblind people. Deafblind manual alphabet Also called finger spelling, this method represents the letters of an alphabet using only the hands. This type of signing makes use of touch by spelling out each word onto a deafblind person's hand. Each letter is signified by a particular sign or location on the hand. Although the Deafblind manual alphabet can take a while to learn it's much faster to use than other methods such as block. Due to it's speed and fluency, this method is one of the most commonly used worldwide. The manual alphabet can be used to denote complex words by spelling individual letters or quickly express simple information such as 'yes' and 'no' through use of quick signs. Block Block is another form of manual communication in which words are spelled out onto the palm of the deafblind person's hand. As opposed to other forms of manual signing, Block makes use of tracing in order to spell the words on the palm. Block can be used to spell out complex words by tracing each letter with your finger in block capitals on the deafblind person's palm. Letter's are placed on top of each other and there are slight pauses to signify the end of a word. It's important to keep letters large and clear as it's easy to mistake similar shaped letters. Although learning Block requires very little tuition, it isn't as fast and is less popular than other signing methods due to the limited speed at which information can be imparted.

what are the main causes of sensory loss
Weegy: If they have sensory loss, they can feel very disconnected with the world around them. The importance of effective communication is to give them a sense of normalcy, that life can be okay again. User: Identify the main causes of sensory loss in the elderly Weegy: Presbycusis, normal age-related changes in auditory function, is caused by anatomical and physiological changes to the entire auditory pathway (Schuknecht, 1974). However, the aging of the auditory system is not uniform throughout the mechanism. [ Age-related changes in the peripheral and central auditory pathways impact speech understanding ability independently, especially in degraded listening conditions (Gates, Feeney & Mills, 2008). ] (More)
