A disease vector is any agent that transmits and carries an infectious pathogen into another living organism. These vectors have immunity to the pathogen and thus allows for the successful transport of the pathogen. Not every vector is able to carry every pathogen and ecological restrains also limit the spread of the disease due to the inability of the vector to survive in different kinds of environments. Arthropods can serve as vectors and play an important role in disease transmission. These vectors include mosquitoes, fleas, sand flies, lice, ticks, and mites.
For instance, though the channel by bites from insects or animals. Beside, others are obtained by consumed contaminated food or drinks which being exposed to the environment with the organisms. In addition, the signs and symptoms of the diseases are extend depending on the organism which causing the infection. For examples which often happen as fever, diarrhea, fatigue, muscle aches, coughing. If the organisms did not very active, the mild infection will respond to rest and home remedies.
This results in the the organism getting infected with the virus (Gale,2013) . The variola virus spreads quickly making it a highly contagious infection to obtain. The virus is acquired through multiple ways such as airborne, bloodborne and physical touch. The virus can also be acquired by having contact with an object that had previous contact with another infected individual (Gale,2013).
It is then shed into the environment through the feces where it can spread rapidly through a community, especially in situations where poor hygiene and sanitation are lacking. Polio can also be transmitted by unwashed hands or contaminated water. The virus depends on survival by invading a host cell, where it
A microorganism is capable of causing diseases, this also known as a pathogen, is what begins with a host. The reservoir host is any living thing that is capable of sustaining growth of a pathogen such as a human, animal and/or an insect. Allowing this microorganism to invade any of the bodies, it can cause an infection to the body
Also, later in life smoking, occupational exposures, or accidents may damage the lungs. These abnormalities allow air pollutants to break through the lung's defences and result in respiratory diseases. Respiratory diseases are pathologies that affect the air passages, including the nasal passages, the bronchi and the lungs. They can be classified in many different ways as of the organ involved, the pattern or symptoms or the cause of the disease. However, the most common can be categorised under two broad types as acute infections, such as pneumonia and bronchitis, and chronic conditions such as asthma or chronic obstructive pulmonary
The evolution of the disease develops in stages and other outbreak in which the effects of the disease forwarded. Also, there are very severe lupus and some not so serious as those that occur and are limited to skin conditions. In general, when a person is diagnosed with lupus, immune cells are attacking own body causing inflammation and tissue
However , a childs immune system may be compromised due to malnourishment and hence are at a higher risk of acquiring the infection. Similarly , pre-existing illnesses like HIV or AIDS also increase the chances of a child contracting pneumonia. 1.12
Due to the organ shortage, many transplanted organs are taken from elderly or ill people. This kind of actions may lead to the occurrence of different diseases in the recipient’s body, failing organs or cancer. However, waiting could be more dangerous, as there is a risk of death (Tabarrok 2010). Moreover, the possibility of doing it legally improve the conditions where the transplantation is done. If before it was done in dirty, unsanitary places with the risk of negative consequences, now it can be prevented.
Introduction Blood and body fluids may contain blood-borne viruses or other bacterial and other viral pathogens. These can present a risk to other patients and health care workers. As it is not always possible to know who is infected with these pathogens, emphasis on infection control effort should focus primarily on 'Universal Infection Control Precautions' (UICP) which prevent the exposure to blood and body fluids Which are presumed to be potentially infective. (KUALA LUMPUR, MALAYSIA APRIL 1995) In this assignment I will talk about the universal precautions that will has Risk assessment talk about Transmission of HIV in health care settings. Then I will mentioned protective clothing for example: gloves, aprons, mask and hand washing .And how To
