Communicable Diseases

Facts and figures available to study the epidemiological data for the outbreak of measles include gathering suspected and confirmed cases of this disease from the World Health Organization. This is done by gathering serum samples from all suspected cases to determine if a measles specific immunoglobulin antibody is detected. This particular disease lives in the nose and throat of the infected individual and is considered contagious for a period of four days before the rash appears and for a further four days after the sighting of the rash.

In early April 2013 a measles outbreak was discovered in North Carolina. By mid-May the outbreak had been identified in Stokes and Orange Counties via 23 active cases. Every case was linked back to a family that had spent 3 months in India and had not been vaccinated. By the 16th of April the state laboratory of Public Health was able to confirm the diagnosis, with the last known case being confirmed on May 7th. The investigation of this outbreak revealed 4 patients with a confirmed diagnosis that had received one of vaccination of the two part series. The other 19 cases had not ever been vaccinated.

Measles is a very contagious disease that is caused by a virus in the paramyxovirus family (World Health Organization, 2016). Measles, a virus only found in humans, can be passed through the air or by direct contact. It can be spread by sneezing, coughing, close personal contact or direct contact with infected nasal or throat secretions. The virus enters the body via mucous membranes and then it is carried throughout the body. Usually when someone has been exposed to measles, the first sign will be a high fever beginning about a week and a half after the exposure and

Welcome to week 4! This week we are discussing what consequences face the Nation if our chosen threat isn’t adequately addressed and whether we believe that it is being addressed adequately now. Of the six security challenges that are mentioned in the 2014 Quadrennial Homeland Security Review, I have chosen to discuss biological threats. Biological terrorism is a scary prospect that should be a growing concern for the country. The reason for this is the ease at which a bio attack can be put into action. Depending on the level of intricacy of the attack, the effects could be isolated to one area or become a pandemic that spreads across the United States. Bioterrorism comes in many forms but as a general explanation biological

In a response to the polio outbreak of 1916, Dr. Haven Emerson, the Health Commissioner for New York City, stated: “we have learned little that is new about the disease, but much that is old about ourselves.” The meaning of this has to do with the ideology that no matter the era, people have a common response to the outbreak of contagious disease. Human nature supplies us as humans with a common reaction to dealing with disease, and it is one that can be seen during the Black Death, polio epidemics, and ebola epidemics, as well as many other epidemics. These responses can be both positive and negative, and often have to do with containment of the disease, preventative measures - which may or may not be effective; and scapegoating. Although there may be individualized responses for each of these diseases, the way in which the health-care officers and the public handle the outbreak of disease generally follows the same pattern overall.

Thirty-nine (35%) of the California patients visited one or both of the two Disney theme parks during December 17–20, where they are thought to have been exposed to measles, 37 have an unknown exposure source (34%), and 34 (31%) are secondary cases. Among the 34 secondary cases, 26 were household or close contacts, and eight were exposed in a community setting. 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).”(CDC, February 11, 2015)

Diseases can be preventable and curable but many still manage to devastate on international scales, whether it was during the Middle Ages or today. These illnesses are sometimes underrated in their effects on the human race where symptoms can range from minimal to down-right devastating and painful. No matter where it started, they can bring devastating effects to the surrounding area. When someone wants to know about a disease, they want to know where it came from, it's symptoms, and how it affected the community in which it appeared. The Black Death, Ebola, and the Zika virus are examples of large-scale illnesses that vary in all three of these topics but still managed to threaten humans on a bigger scale than expected. Diseases like the

As of January 2015, it was reported that at least two dozen people were infected with Measles between

Unvaccinated people can cause outbreaks of viruses that have been eradicated. In late 2014 a measles outbreak occurred when an unvaccinated child who was a carrier of the disease visited Disneyland. This caused 173 people from seventeen different states to contract the virus that was eradicated from the United States in 2002. In order for measles to be under control 94-99% of the population must be vaccinated. With the recent trend of not vaccinating, measles, along with other once eradicated, or nearly eradicated diseases are making a come-back.

Measles, is a highly contagious viral illness that is characterized by a prodrome of fever, malaise, cough, coryza, and conjunctivitis and then is followed by a maculopapular rash (Kutty et al., 2014). Most persons contracting the virus recover completely, but there are some possible severe complications and these include pneumonia, encephalitis and death (Kutty et al., 2014). Kutty et al. (2014) reported deaths from the measles as approximately two to three deaths for every 1,000 reported cases.

In fact, life-threatening diseases still exist. There have been outbreak cases in the past two years which started in an unvaccinated community, demonstrating it is highly important to vaccinate and that disease is still around. In 2013, the United States experienced eleven outbreaks with twenty or more cases. In 2014, the United States experienced twenty-three measles outbreaks, including 383 cases, which by the way occurred among the unvaccinated community of Amish people in Ohio (Measles). In 2015, again the US experienced one of its largest measles outbreak which started at Disneyland (Measles). The outbreak started through a traveler which then spread it to surrounding people (Measles). A majority of these people who caught the disease were unvaccinated and had no immunity built to defend off the virus. Diseases, such as the measles, has not yet been eradicated and still persists in countries around the world. People who travel abroad bring the disease back and put unvaccinated people in danger. Disease still exists and in order to prevent from catching anything, a person must be

In 2008 140 measles cases were reported in the United States. Travelers to Italy, Switzerland, Belgium, India, Israel,

Over the centuries the world has knocked on death’s door, and it has been pushed over the threshold by disease and plague. In each case something has caused this extra push. The sickness is bad enough, but something else has posed a threat.This extra threat is the frenzy and madness that comes with each outbreak. People choose to let their fear get the best of them. Mass hysteria and fear are hindering effective Ebola containment in spite of the United States’ high level of preparation and a multitude of worldly issues to fret about.

Biosecurity as a definition, according to the textbook, Biosecurity and Bioterrorism Containing and Preventing Biological Threats, by Jeffrey R. Ryan, is the measures taken to help protect a nation’s food supply, as well as, agricultural resources from a biological terrorist attack (Ryan, 2016, p. 26). Similarly, the term Biodefense as a definition, according to the textbook Biosecurity and Bioterrorism Containing and Preventing Biological Threats, by Jeffrey R. Ryan, is a procedure designed, by a nation, to protect and improve biological defenses in the case of an attack (Ryan, 2016, p. 26). Why is bioterrorism such an extremely effective way to bring terror to divergent countries? Pursuing this further, most of the common biological agents found in pathogens are obtained from a natural environment (Ryan, 2016, p. 31). In fact, these “biological

Of the many diseases spread by insects, none are actually caused by the insects themselves but by other organisms passed on when they feed or bite. Insects are capable of spreading diseases caused by many different types of microorganisms including bacteria, viruses, protozoan and others. Mosquitoes have earned the title of "the most deadly creature on earth." This is due to the fact that they spread serious epidemic diseases such as Malaria, Yellow Fever, African Sleeping Sickness, and West Nile Virus.
