Emerging And Re-emerging Infectious Diseases

The statement is stating a fact about the global and US mortality rates. It says that infectious diseases continue to be the leading cause of death worldwide and the third leading cause of death in the US. This means that infectious diseases are responsible for a significant number of deaths both globally and in the US.

AIDS (Acquired Immunodeficiency Syndrome) is considered an emerging disease because it was first identified in the early 1980s and has since spread rapidly worldwide. It continues to be a major global health issue, with new cases being reported every year. The ongoing research and efforts to control and prevent the spread of HIV (Human Immunodeficiency Virus), which causes AIDS, indicate that it is still an emerging disease.

In 2003, SARS (Severe Acute Respiratory Syndrome) was recognized as an emerging disease. SARS is a viral respiratory illness caused by the SARS-CoV virus. It first emerged in China and quickly spread to other countries, causing a global health crisis. The disease is characterized by flu-like symptoms such as fever, cough, and difficulty breathing. SARS was a significant concern due to its high mortality rate and the potential for rapid transmission. Efforts were made to contain the outbreak and develop effective treatments and preventive measures.

Tuberculosis is considered an example of a re-emerging disease because it was largely under control in developed countries during the mid-20th century, but has since resurfaced with increased incidence and drug resistance. The emergence of HIV/AIDS, globalization, poverty, and inadequate healthcare systems have contributed to the re-emergence of tuberculosis as a major public health concern.

Re-emerging diseases can indeed be a health problem for a significant portion of the population. This is because these diseases, which were previously under control or eradicated, have started to resurface and affect a considerable number of individuals. The re-emergence of such diseases can lead to outbreaks and epidemics, causing illness, suffering, and in some cases, even death. Therefore, it is crucial to address and manage these diseases effectively to protect the health and well-being of the affected population.

Rubella and Pertussis are examples of re-emerging diseases because they were previously under control or had low incidence rates, but are now experiencing a resurgence in cases. This can be due to various factors such as decreased vaccination rates, waning immunity, and changes in the pathogens themselves. Re-emerging diseases pose a significant public health concern and require renewed efforts for prevention and control.

The given answer is "malaria". Malaria is a disease caused by a parasite that is transmitted through the bites of infected mosquitoes. The question is likely asking for a factor that contributes to the spread of malaria, and the answer is the disease itself. Malaria can lead to drug resistance, meaning that the parasites become resistant to the drugs used to treat the disease. Additionally, favorable conditions for mosquitoes, such as warm and humid environments, also contribute to the spread of malaria.

In 1977, Ebola was recognized as a viral hemorrhagic fever when it was first identified in the Democratic Republic of Congo (formerly Zaire) and Sudan. The virus was named after the Ebola River in Congo, where the first outbreak occurred. This discovery led to further research and understanding of the virus, its transmission, and the development of diagnostic tests and potential treatments.

Pertussis and Rubella are not examples of re-emerging diseases. Pertussis, also known as whooping cough, has been a persistent disease for many years and has not experienced a significant resurgence. Rubella, also known as German measles, has been effectively controlled through vaccination programs, resulting in a decline in cases. Therefore, the statement that Pertussis and Rubella are examples of re-emerging diseases is false.
