If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.Measles is so contagious that if one person has it, up to 90% of the people close to that person who are not immune will also become infected. A patient sick with a communicable disease may be treated with antibiotics to eliminate the infection. The reservoir may or may not be the source from which an agent is transferred to a host. As noted earlier, a carrier is a person with inapparent infection who is capable of transmitting the pathogen to others. Measles: It's affect on the Body People that have not been vaccinated or have been around an affected person. Asymptomatic or passive or healthy carriers are those who never experience symptoms despite being infected. Convalescent carriers are those who have recovered from their illness but remain capable of transmitting to others. Principles of epidemiology, 2nd ed. This will eliminate the mosquito eggs and larvae and reduce the number of mosquitoes present in these areas.For travelers to areas with dengue, as well as people living in areas with dengue, the risk of being bitten by mosquitoes indoors is reduced by utilization of air conditioning or windows and doors that are screened. Other Morbillivirus are the cattle rinderpest virus (likely parent virus) and the ca- nine distemper virus.
Vaccinations promote development of specific antibodies that protect against infection. Other portals of entry include the skin (hookworm), mucous membranes (syphilis), and blood (hepatitis B, human immunodeficiency virus).Source: Centers for Disease Control and Prevention.
Homework Help.
As described above, the traditional epidemiologic triad model holds that infectious diseases result from the interaction of agent, host, and environment. On the other hand, prophylactic use of antimalarial drugs, recommended for visitors to malaria-endemic areas, does not prevent exposure through mosquito bites, but does prevent infection from taking root.Finally, some interventions attempt to prevent a pathogen from encountering a susceptible host. The smallest blood vessels (capillaries) become excessively permeable (“leaky”), allowing the fluid component to escape from the blood vessels. For example, bed nets are used to protect sleeping persons from being bitten by mosquitoes that may transmit malaria. Centers for Disease Control and Prevention. A dentist’s mask and gloves are intended to protect the dentist from a patient’s blood, secretions, and droplets, as well to protect the patient from the dentist. When a blister (caused by adult female worm) comes into contact with water, it rapidly becomes an ulcer through which the adult female worm releases first-stage larvae. Residents are responsible for keeping their yards and patios free of sites where mosquitoes can be produced.Source: Centers for Disease Control and Prevention [Internet]. Monkeys may serve as a reservoir in some parts of Asia and Africa. The portal of exit for measles is the respiratory. They should also rest, drink plenty of fluids, and consult a physician. Factors that may increase susceptibility to infection by disrupting host defenses include malnutrition, alcoholism, and disease or therapy that impairs the nonspecific immune response.Knowledge of the portals of exit and entry and modes of transmission provides a basis for determining appropriate control measures. The reservoir of an infectious agent is the habitat in which the agent normally lives, grows, and multiplies. To prevent fecal-oral transmission, efforts often focus on rearranging the environment to reduce the risk of contamination in the future and on changing behaviors, such as promoting handwashing. An individual’s genetic makeup may either increase or decrease susceptibility. Measles can infect anyone of any age, but most of the burden of disease globally is still among children < 5 years of age. [updated 2005 Aug 22]. Persons who think they have dengue should use analgesics (pain relievers) with acetaminophen and avoid those containing aspirin.
