Viral skin diseases were eradicated through vaccination programs, however, I believe they are resurfacing such as Smallpox, Poliomyelitis (polio), malaria, and hookworm for reasons such as parents/ guardians not vaccinating a child or it can also be because of travelers reintroducing the diseases. The World Health Organization, a United Nations specialized agency in charge of universal public health, reported that the rise in measles is a direct result of anti-vaccination movements (WHO 2020). According to the CDC, you can help prevent your child from as many as 14 diseases before the age of 2!Malaria is an endemic in West Africa (Cowan 2017), caused by a microorganism that is spread by mosquitoes and kills between 440,000 and 700,000 people worldwide each year. Since mosquitoes are most aggressive in the nighttime, the safest way for inhabitants of developed countries to prevent infection with the malaria-causing agent is to sleep under a bed net (Cowan 2017). According to the CDC (2020), “Africa is the most affected due to a combination of factors: A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission. The predominant parasite species is Plasmodium falciparum , which is the species that is most likely to cause severe malaria and death.”Fun Fact (but no so fun): Before the time of antibiotics, doctors reasoned that patients who had syphilis should be treated with malaria, in which the high temperature would kill the relatively fragile bacterium, and then they could cure the patient of the malaria with quinine. It performed on occasion; of course, once antibiotics became available, this practice became obsolete. Being infected with malaria has been used to also treat patients with HIV (1990’s), and even more recently, Lyme Disease (Cowan 2017).Ebola is a virus (that was seen more in Africa although other countries have had cases as well) that can cause extensive bleeding, organ failure, and even death; unfortunately on the rise. Ebola has a high death rate, and other diseases which can cause long-term disabilities such as polio, neonatal rubella. By contact with body fluids such as blood, humans will transmit the virus to other humans. Fever, fatigue, body pain, and chills are among the first symptoms. Internal bleeding can occur later, resulting in bloody vomiting or coughing. According to the CDC (2020), “Factors like population growth, encroachment into forested areas, and direct interaction with wildlife (such as bushmeat consumption) may have contributed to the spread of the Ebola virus. Since its discovery in 1976, the majority of cases and outbreaks of Ebola Virus Disease have occurred in Africa.”There are currently no vaccines for malaria or ebola.The CDC is in charge of preventing the development and transmission of infectious diseases, as well as providing advice and support to other countries and foreign organizations in order to help them improve their disease prevention and control, environmental protection, and health promotion efforts.

Initial Post InstructionsSome microorganisms like Staphylococcus, Streptococcus, Yesinia pestis, E. coli can cause diseases of different body systems. Let’s investigate how the same pathogen is responsible for different pathophysiological symptoms. First, choose a microorganism found in multiple systems. Then, describe your pathogen’s role in disease for one body system: report the disease caused, the normal function of that system, pathophysiological symptoms, and the virulence factor(s) that contribute(s) to the diseased state.

Forensic biology is a scientific method of examining, testing, and probing evidence from a crime scene investigation. When you review the history of forensics, you see that there are varying timelines. The history, as compiled by the American College of Forensic Examiners, began as early as the 4,000 BCE. The modern association of forensic biology has been developed into many subdivisions such as toxicology, pathology, anthropology, and odontology, just to name a few.Address the following in your main post:In your own words, what is the definition of forensic biology? Explain.Which of the major subfields do you feel is the most important to forensic biology?

You are a member of a forensic team that just finished gathering samples from a crime scene for which someone is being accused of breaking into the house and possibly attacking a female. The female victim was home alone when she heard a noise and went to investigate. A man was found running from the neighborhood a few blocks away when the police arrived. They arrested him, pending the outcome of the forensic investigation. Your forensic team surveyed the crime scene area and gathered evidence to take to the lab for investigation. The evidence consisted of broken glass, stains from carpet, furniture and clothing, and drinking glasses.AssignmentsAddress the following in 4–5 pages:How will the evidence be delivered to the lab for testing? Explain.How would you test for the following body fluids on each of the pieces of evidence (explain in detail):BloodSemenSalivaDescribe what a positive test for each of the samples would indicate.Be very descriptive in your examination.How are the tests for the 3 above body fluids similar? Explain.How are the tests for the 3 above body fluids different? Explain.

Board of Education was an unjustified grab for political power by the U.S. Supreme Court. The decision violated classical republican norms by dictating policy to democratically elected state legislatures. It violated classical liberal norms by replacing one form of required social ordering – segregation – with another required form – integration- instead of leaving citizens free to choose with whom to associate. It violated common law norms by overturning a long-standing precedent without finding that Plessy’s reasoning was defective. The only justification for the decision was a weak appeal to social science. In Brown, the Court exceeded the constitution’s limits on U.S. Supreme Court authority and unconstitutionally pre-empted state legislative prerogatives.
