To explain:
Why it is more difficult to eliminate the AIDS than smallpox and what would be involved in an eradication program of HIV infection?
Concept introduction:
The Acquired immunodeficiency syndrome is a syndrome that caused by a virus Human immunodeficiency virus (HIV). The Human immunodeficiency virus infection (HIV) is a subgroup of retrovirus that causes HIV infection. The AIDS is the last and serious stage of HIV disease and cause extreme damage to the immune system.
Explanation of Solution
The smallpox is an infectious disease that caused by two virus variants includes variola minor and variola major. By immunization, the smallpox have been primarily controlled and eradicated. The diseases are only eradicated, if those who have contracted the disease and complete contacts are immunized and treated. This strategy is employed successfully by the World Health Organization (WHO).
When the humans are the disease reservoir. Example, HIV/AIDS can be difficult to control and eradicate because once the genetic material of the HIV incorporated into an infected cell. It will insists throughout the part of the lifetime of the cells. Thus, the AIDS is more difficult to eradicate than the smallpox.
The high risk of AIDS occurs to the individual who is receiving blood and blood products from infected peoples. The HIV eradication program can be achieved by educating the people of safe sexual practices and reducing the chances of transmission through media of blood.

- Which statistic below is the best example of incidence of a disease? A) In 2005, 2 million people died from HIV B) A total of 40 million people have died from HIV infection C) In 2005, 4 million people acquired HIV D) A total of 65 million people have gotten HIV E) 25 million people currently suffer from HIV infectionarrow_forwardCompare the prevalence of neglected tropical diseases to the much better known and deadlier HIV/AIDS. Discuss two reasons why would it make sense to shift health funding toward these diseases and away from HIV research?arrow_forwardWhich link in the chain of infection is the intervention described below meant to break? "N95 respirators reduce the wearer's exposure to airborne particles, from small particle aerosols to large droplets. N95 respirators are tight-fitting respirators that filter out at least 95% of particles in the air, including large and small particles." (https://www.cdc.gov/coronavirus/2019- ncov/hcp/respirator-use-faq.html) Portal of entry Means of transmission O Infectious agent Susceptible hostarrow_forward
- The initial symptoms of HIV infection are followed by clinical latency. Which of the following statements is true? Clinical latency is a symptomatic period of infection. The clinical latency period usually lasts less than a year. Clinical latency is the second stage of HIV infection and can last anywhere from 3 to 20 years. Patients usually become overweight or obese during clinical latency.arrow_forwardWhich of the following best explains why vaccination of humans against rabies can be delayed until after exposure to a potential source of infection? A) Antibody responses are more rapid than those against other viruses B) T lymphocyte responses are more rapid than those against other viruses C) The virus does not infect any cells for several weeks or months D) The virus does not reach i target organ for several weeks or monthsarrow_forward(1)Why do you think that SARS-CoV-2 caused Covid-19 became a pandemic, whereas other similar viruses have remained more contained? & What step(s) would you like to see in place as we continue to learn and combat the pandemic spread of Covid-19 disease? (2)What are your concerns, or thoughts, going forward as we (the United States and the global human population) continue to face this pandemic and move towards vaccine testing/approval?arrow_forward
- Why is it helpful for scientists to use models to simulate the spread of a communicable disease?arrow_forwardBelow are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)arrow_forwardWhich of the following is LEAST helpful in explaining why the incidence of HIV/AIDS is higher in Sub-Saharan Africa than elsewhere? Group of answer choices The disease has been in Sub-Saharan Africa longer than in other regions. The warm, wet conditions in much of the region are favorable to the growth of mosquitoes. Sub-Saharan Africa is poorer than other regions. Many African men engage in long-distance mobility to work in mines and distant cities.arrow_forward
- Which of the following is NOT true about the current coronavirus global pandemic (COVID-19)? Laboratory diagnosis of infection is based on polymerase chain reaction (PCR) testing of patient samples for RNA from the causative virus Nucleic acid vaccines to prevent COVID-19 (and/or its most severe forms) are authorized for use in the US Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Person-to-person transmission can occur through respiratory secretions (droplets and/or aerosols) None of the other four answers (All are true about COVID-19arrow_forwardYearly vaccination is the primary means of preventing and controlling flu outbreaks. Here 'yearly' is important because: New vaccines with better efficacy are produced each year Circulating strains of influenza viruses change from year to year New vaccines with up-to-date strain components are produced each year Who is at higher risk of developing severe pneumonia when infected with SARS-CoV-2? An undergraduate A student at high-school A 6-month-old baby A 70 years old man with diabetes and high blood pressurearrow_forwardHuman papillomavirus (HPV) is a viral infection that can be passed through sexual contact and affect the genitals, mouth, or throat. A vaccine that prevents infections from several of the common strains of HPV was developed in 2006. When the HPV vaccine was first developed, it was initially administered only to girls in most jurisdictions. Now, the HPV vaccine is provided free to both boys and girls in all the provinces and territories, although eligible ages vary. Alberta was one of the first provinces to include boys in their HPV immunization program. Currently, in Alberta, Grade 6 students are routinely immunized against HPV and the HPV immunization program is free for all students until the end of Grade 12. It has been established that 2 doses of the vaccine over 6 months are effective in individuals under 15 years of age. Individuals over 15 need 3 doses over 6 months. The cost of a single dose is about $200. When the HPV vaccine was first introduced, it was recommended…arrow_forward
