Measles is a very contagious virus that thrives in the mucus found in the throat and nose. Measles is transmitted through the coughing and sneezing of an infected person. This virus can live up to two hours in the air where the infected person coughed or sneezed. Measles is so infectious that 90% of nonimmune people who are around an infected person will become sick. The rash that appears when a person is infected with measles signals when the virus can be spread. A person can easily spread the virus four days before the rash appears and four days after the rash appears. The beginning symptoms of the measles virus includes: high fever, cough, runny nose, and red, watery eyes. The rash typically forms three to five days after these symptoms, …show more content…
The life expectancy at birth of the total population is 75 years old (Central Intelligence Agency). With China having a significant amount of the measles cases in the Western Pacific region, this country suffers great morbidity from the virus (Chao Ma et al, 340). Between 1970 and 1979, the average incidence of measles recorded in China was 355.3 per 100,000. Between 1980 and 1989, the average incidence of measles was 52.9 per 100,000. Between 1990 and 1999, the average incidence of measles was 7.6 per 100,000 (Chao Ma et al, 340). Since 2000, the incidence has stayed below 10 (Chao Ma et al, 340). In 2006, a national action plan was created to eliminate measles in China. This plan was to go through 2012 and use strategies such as immunization and measles surveillance (Chao Ma et al, 340). In September 2010, organized nationwide immunizations took place across China. These immunizations reached a coverage of 97.52% (Chao Ma et al, 341). Great success was seen through this action plan; however, in 2013 there was a reappearance of measles among young children who were unvaccinated (Chao Ma et al, 345). This shows how important it is for China to have routine vaccine programs to make sure no child has been
The Latin name for measles is rubeola. The pathogen which causes the disease is a paramyxovirus, which is one of a group of RNA (ribonucleic acid) viruses. Measles is a respiratory disease caused by a virus, and also comes out in a rash. The virus enters the body via the respiratory system, and grows in the cells at the back of the throat and in the cells that line the lungs, from there it then enters the blood stream and circulates the body.
The first Measles vaccination was introduced in 1963, the improved upon in 1968. During the years of 1967 and 1968, a vaccination for Mumps and Rubella was also introduced. The three vaccines were combined in 1971, and called the measles-mumps-rubella (MMR) vaccine (Immunization Action Coalition, “Measles: Questions and Answers”). One dosage of the MMR vaccination was proven to protect about 90-95% of children, then in 1989 the Center for Disease Control and Prevention (CDC) and Prevention’s Advisory Committee on Immunization Practices decided to change the dose from one to two, raising the percent of children protected to about 97% (National Network for Immunization Information (NNii), “Measles, Mumps, Rubella (MMR)”). The CDC reported that 95% percent of children receiving their first dose of the MMR vaccine between the ages of 12 months and 15 months become immune to measles, mumps, and rubella after this initial dose. Those not becoming immune after the first does become immune after the second dose given between ages four years old and six years old (Centers for Disease Control and Prevention, “Vaccines”). Thanks to these changes made measles, mumps, and rubella have become nearly eliminated in the United States. However, to ensure that these diseases do not spread from countries not vaccinating, it is important that we continue with our current program. While the MMR vaccination is the safest way to ensure that we do not have an outbreak, the vaccination has been a source of controversy over the years. At one time, the MMR vaccine was thought to be unsafe because not only does it overwhelm your immune system, but also the vaccine contained toxic additives, and was thought to be linked to Autism. Studies have since pro...
The syndrome was first described in 1922, when the American pediatricians Albert Mason Stevens and Frank Chambliss Johnson reported the cases of 2 boys aged 7 and 8 years with "an extraordinary, generalized eruption with continued fever, inflamed buccal mucosa, and severe purulent conjunctivitis". Both cases had been misdiagnosed by primary care physicians as hemorrhagic measles (Foster, 2011).
Among the 34 secondary cases, 26 were household or close contacts, and eight were exposed in a community setting. Five of the California patients reported being in one or both of the two Disney theme parks during their exposure period outside of December 17–20, but their source of infection is unknown. In addition, 15 cases linked to the two Disney theme parks have been reported in seven other states: Arizona (seven), Colorado (one), Nebraska (one), Oregon (one), Utah (three), and Washington (two), as well as linked cases reported in two neighboring countries, Mexico (one) and Canada (10).” (Measles Outbreak, 2016). In California, 45% of the patients were unvaccinated, while 5% had one dose of the measles-containing vaccine, 6% had two doses, one had three doses, 43% had unknown or undocumented vaccination status. (Who Outbreak, 2016). Pointing out that almost half of the cases are in unvaccinated patients making it important that all received the measles vaccinations. Specimens from 30 California patients were genotyped; all were measles genotype B3, which has caused a large outbreak recently in the Philippines, but has also been detected in at least
A person who has been infected by the disease may experience signs of fatigue, loss of appetite, fever, sore throat, swollen lymph nodes, and a red rash that appears blotchy. Generally the signs become present between ten and twenty-one days after the person has been exposed to and infected by the virus (Silverstein et al., 1998). This is what is known as the incubation period (Plum, J., 2001). The rash is most likely to begin on the chest, back, or the scalp, but will soon spread to the rest of the body. After a couple days of having physical evidence of the infection, the rash will s...
For example, in China, the measles vaccine consisting of two doses was first introduced in the National Expanded Program on Immunization. The Zhejiang provincial EPI program noticed that measles was beginning to decrease due to the vaccine, while mumps and rubella was still spreading. This is when the MMR vaccine was introduced and implemented. By 2007 the second dose of MV was replaced by the MMR vaccine. Following this development the rate of measles reached a historical low in 2011 due to the vaccine produced by the EPI. Not only did the cases of measles decrease but so did the cases of rubella with the introduction of the combined vaccine (He, n.p.). Additionally, a record 9,120 cases of pertussis were reported in California in 2010 the most since 1947. A study conducted by the American Academy of Pediatrics was done to determine how this disease was spreading. Their results showed that among other factors the large amount of unvaccinated children in one area was a major contributor to the clusters of pertussis. There was a strong correlation between communities with a large number of unvaccinated children and pertussis outbreaks in California. This could have been avoided due to the fact that pertussis is a vaccine-preventable disease. The importance of vaccines can be seen through the results of this study, which show that parents intentionally avoiding the
In 1960 America was ranked 12th in the infant mortality rate among all other nations in the World and by 2005 we were ranked 30th. The United States distributes more vaccines to infants t...
It is classified as an acute viral respiratory illness. Measles is sometimes referred to by the virus that causes it which is the Rubella virus. It’s most characteristic to identify by is Koplik spots. Chickenpox is also known to be a highly contagious virus with fever-like symptoms. It is common in children.
... presented by the diagram on the side. In this diagram some countries in Asia, Africa and South America have coverage of less than 89% of infants immunised. Two African countries, Somalia and Central African Republic have a rate of below 50%. The disease could also be prevented from re-emerging in countries where it has been eradicated by thoroughly promoting personal and environmental hygiene. The disease can also be eradicated in the other 3 countries by educating parents in rural areas about vaccinations and good hygiene as the disease is mainly spread through faeces
Vaccines have been around for hundreds of years starting in 1796 when Edward Jenner created the first smallpox vaccine. Jenner, an English country doctor noticed cowpox, which were blisters forming on the female cow utters. Jenner then took fluid from the cow blister and scratched it into an eight-year-old boy. A single blister came up were the boy had been scratched but it quickly recovered. After this experiment, Jenner injected the boy with smallpox matter. No disease arose, the vaccine was a success. Doctors all around Europe soon began to proceed in Jenner’s method. Seven different vaccines came from the single experimental smallpox vaccine. Now the questions were on the horizon. Should everyone be getting vaccinations? Where’s the safety limit? How can they be improved? These questions needed answers, and with a couple hundred years later with all the technology, we would have them(ncbi.nlm.nih.gov).
After a few days after developing a rash, it may change into small lumps all over the body. These symptoms may come just after a week of being infected. "The first symptoms may appear 12 to 14 days after you're infected." A rash will appear in the mouth and throat in the first few days, it will then spread to the face and arms and finally, the legs. The rashes will grow bigger as days go by, eventually transforming into large bumps filled with puss and fluid. Then these bumps are replaced with blisters, which will drop off and that indicates that the person has become infected and can possibly spread the disease.
Vaccinations have significantly reduced the disease rate throughout the world. Usually, vaccines prove to be between 90 and 99 percent effective. This reduces disease and mortality rate by thousands every year (Jolley and Douglas 1). On average, vaccines save the lives of 33,000 innocent children every year (“Vaccines” 1). In addition, if a vaccinated child did contract the vaccine’s targeted illness, that child would, in general, have more mild symptoms than an unvaccinated child that contracts the same illness. These vaccinated children will have less serious complications if they do contract the disease; they will be much more treatable, and have a lower risk of death (Jolley and Douglas 2). The risks of not vaccinating greatly outweigh the small risks of vaccination. Diseases like measles and mumps can cause permanent disability. While there i...
Measles is a highly contagious disease. It is caused by an RNA virus that changes constantly. Measles symptoms usually include a bad cough, sneezing, runny nose, red eyes, sensitivity to light, and a very high fever. Red patches with white grain like centers appear along the gum line in the mouth two to four days after the first symptoms show. These patches are called Koplik spots because Henry Koplick first noticed them in 1896. The Spots are important to diagnose measles. A characteristic red rash in measles is red spots starting at the hairline and going down to the face, body, and limbs.
Now it is rare for a child to get the measles. The decline in the disease has been attributed to vaccinations and their high success rate. According to ‘Childhood Vaccinations are Important for Public Health”, “by vaccinating we will make sure these 14 diseases will not become everyday events for our children.”. There are quite a few reasons why parents should not vaccinate their children. Some believe that it will cause harm to their children because of rumors.
Chicken pox is not an Entrée that is served at one’s family holiday dinner party. Chicken pox is an extremely contagious disease caused by the Varicella zoster virus. Chicken Pox is not a disease that is known to affect other animals or insects. Unlike other diseases, where human and other animal close interaction causes the exchange of virus and disease this disease did not come from a human-chicken interaction. The name chicken pox has been stuck for generations; there are many theories behind its name. Chicken pox could sneak up on its young victims in the form of an innocent touch, or by inhaling tiny particles from a cough, or sneeze which then enters the respiratory tract. Once the virus attaches itself to it gracious, and unwilling host cells it causes a crimson rash that could be located on different parts of the body. The rash is highly irritating which makes it almost impossible not scratch. In the United States each year about 5,000 to 9,000 people are hospitalized, and around 100 people die from the microbe Varicella zoster that causes chicken pox.
