The Measles Virus

Decent Essays

day, the measles virus has been largely contained by scientists’ understanding of how the measles affect the human body’s cells and organs, as well as the development of technology in providing a readily available vaccine. Scientists have for long conducted epidemiological studies which have provided them with the causes and effects of this highly contagious virus. The results bolster a hypothesis that the measles virus weakens the immune system after being entered through the nose, mouth or eyes. Research shows that after the virus has entered the human body, it travels to the lungs where the body’s first line of defence, macrophages, powerful guard cells that protect the lungs from intruders, enter the cell and take over. The virus reprograms …show more content…

If these cells discover that there is any infected cells, simply, they kill them. The effectiveness of this results in one being oblivious to the fact they are affected by the virus for the first initial 10 days. After a period of fighting and dying, the macrophages alert the brain of the immune system; the dendritic cells. The function of the dendritic cells is to collect samples of intruders, travel to the lymph nodes and then activate the heavy weapons that eradicate the infection very fast in a team effort. Nonetheless, the measles virus uses a wrecking tactic that infects the dendritic cells and uses them to enter further into the body. Those infected cells travel to the next lymph to alert other immune cells. Upon arrival the measles virus spreads around the T and B cells and infects them, attacking the very system that was meant to fight it. The lymph system then spreads the virus everywhere and it enters the bloodstream infecting cells while travelling. Measles infects organs such as the Spleen, intestines, lungs and liver and results in symptoms such as high fever, headache, sickness, bronchitis and of course the …show more content…

After proving that the vaccine was both safe and efficient, first by experimenting on monkeys and then humans, John Enders and his colleagues announced their measles vaccine that was capable of preventing the virus (The College of Physicians of Philadelphia, 2015). The measles, mumps and rubella (MMR) vaccine contains small traces of each virus. The vaccine is such as a success as it triggers the immune system to produce antibodies against all three viruses. Thus, when one comes into contact with one of these highly contagious viruses, the immune system will recognise it and immediately produce the antibodies needed to fight it (Better Health, 2015). Regular routine MMR vaccination for children, with additional mass immunization campaigns in countries with high numbers of outbreaks and deaths, are key public health strategies to reduce global measles deaths (World Health organization, 2015). In 2013, about 84% of the world's children received 1 dose of measles vaccine by their first birthday through routine health services – up from 73% in 2000. Two doses of the vaccine are recommended to ensure immunity and prevent outbreaks, as about 15% of vaccinated children fail to develop immunity from the first dose (World Health Organization, 2015).
