An epidemiologist has identified the distribution of diseases among the population by four types.
Which is the most likely identification of the constant presence of disease in a specific area during the time?
Correct Answer
A. Endemic
Explanation
The most likely identification of the constant presence of disease in a specific area during the time is "Endemic." Endemic refers to a disease that is regularly found in a particular area or population. It is constantly present at a relatively stable frequency within that area, without causing significant fluctuations or widespread outbreaks. This suggests that the disease is well-established and has become a part of the normal health profile of the population in that specific area.

Vector-borne diseases are still an issue affecting the health of developing countries.
What is the vector that causing the greatest number of deaths globally?
Correct Answer
B. Malaria
Explanation
Malaria is the vector that causes the greatest number of deaths globally. Malaria is transmitted through the bite of infected female Anopheles mosquitoes. It is a life-threatening disease that primarily affects people in tropical and subtropical regions. According to the World Health Organization, there were an estimated 229 million cases of malaria worldwide in 2019, resulting in approximately 409,000 deaths. Malaria disproportionately impacts developing countries, particularly in sub-Saharan Africa, where the majority of malaria deaths occur. Efforts to control and prevent malaria, such as the use of insecticide-treated bed nets and antimalarial medications, are crucial in reducing its impact on public health.

In the Shah Alam, modelling study to predict the number of hospital-associated infections among hospital admitted patients averted in the next five years.
Which of the followings is the most important practice to reduce hospital-associated infections?
Correct Answer
A. Hand washing.
Explanation
Hand washing is the most important practice to reduce hospital-associated infections because it is a simple and effective way to prevent the spread of germs. By washing hands properly and regularly, healthcare workers can remove bacteria and viruses from their hands, reducing the risk of transmitting infections to patients. Hand washing is especially crucial in healthcare settings where patients may have weakened immune systems and are more vulnerable to infections. Isolation of infectious disease patients, reverse flow hospital rooms, and gloves are also important infection control measures, but hand washing is considered the most essential and fundamental practice.

In Malaysia, Yellow fever vaccination is required for all visitors who are coming from Yellow fever endemic countries.
What is the main reason for this requirement?
Correct Answer
A. The presence of Aedes mosquito contribute to its potential occurrence in Malaysia.
Explanation
The main reason for requiring Yellow fever vaccination for visitors coming from Yellow fever endemic countries in Malaysia is the presence of Aedes mosquitoes, which contribute to the potential occurrence of the disease in the country. Aedes mosquitoes are known to transmit the Yellow fever virus, and their presence increases the risk of the disease spreading in Malaysia. By requiring vaccination, the country aims to prevent the international spread of Yellow fever and protect its population from the disease.
5.
In which of the following circumstance(s) the prevalence of a disease in the population increase.
Correct Answer
D. If survival time with the disease increases
Explanation
If survival time with the disease increases, it means that individuals who have the disease are living longer. This leads to a higher prevalence of the disease in the population because there are more people living with the disease at any given time. Even if the incidence rate of the disease falls or if recovery is faster, the overall prevalence will still increase if the survival time with the disease increases. The discovery of a new medication to cure the disease would not necessarily increase the prevalence, as it could lead to a decrease in the number of individuals living with the disease.
6.
Metabolic syndrome risk factors the double risk of blood vessel disease and heart disease, which can lead to heart attacks and strokes. These risk factors increase your risk of diabetes by five times.
Which of the following has the highest risk for metabolic syndrome?
Correct Answer
A. Body mass index more than 30
Explanation
Individuals with a body mass index (BMI) greater than 30 have the highest risk for metabolic syndrome. Metabolic syndrome is a cluster of conditions that include high blood pressure, high blood sugar levels, excess body fat around the waist, and abnormal cholesterol levels. Obesity, indicated by a BMI over 30, is a major risk factor for metabolic syndrome. This is because excess weight and fat contribute to insulin resistance, inflammation, and other metabolic dysfunctions that increase the likelihood of developing the syndrome. Therefore, individuals with a BMI over 30 are at the highest risk for metabolic syndrome.
7.
Currently, the population begins to increasingly gain weight which may increase the risk of non-communicable diseases .
The most important step in health prevention and control program of a community is:
Correct Answer
C. Knowledge of local needs
Explanation
In order to effectively prevent and control non-communicable diseases in a community, it is crucial to have knowledge of the local needs. This understanding allows for the identification of specific health issues prevalent in the community and helps in tailoring prevention and control programs accordingly. By being aware of the local needs, healthcare professionals can design targeted interventions, educate the community about healthy lifestyles, and provide appropriate resources and support. This approach ensures that the health prevention and control program addresses the specific challenges and risk factors faced by the community, ultimately leading to better health outcomes.
8.
Programs that aim to reduce the mortality and morbidity involved with the particular disease through treatment programs and rehabilitation are considered:
Correct Answer
C. Tertiary prevention
Explanation
Tertiary prevention refers to programs that focus on reducing the impact of a disease or condition by providing treatment and rehabilitation. These programs aim to improve the quality of life for individuals who already have the disease and prevent further complications or worsening of the condition. This is different from primary prevention, which focuses on preventing the disease from occurring in the first place, and secondary prevention, which focuses on early detection and intervention to prevent the progression of the disease. Primordial prevention refers to measures that aim to prevent the development of risk factors for diseases.
9.
According to estimates based on disability-adjusted life years, which of the following will be the greatest cause of disability-adjusted life years globally?
Correct Answer
A. Cardiovascular
Explanation
Cardiovascular diseases are considered the leading cause of disability-adjusted life years globally. This is because cardiovascular diseases, such as heart attacks and strokes, are prevalent worldwide and can result in long-term disabilities and reduced quality of life. These diseases often require ongoing medical management and can lead to significant limitations in functioning and daily activities. Additionally, cardiovascular diseases are associated with high mortality rates, further contributing to their impact on disability-adjusted life years.
10.
The morbidity rate is calculated as
Correct Answer
D. The number of new cases of a disease during a specified period divided by a number of individuals in the population
Explanation
The morbidity rate is calculated by dividing the number of new cases of a disease during a specified period by the number of individuals in the population. This rate helps to measure the incidence or occurrence of a disease in a population. It provides valuable information about the spread and impact of a disease, allowing public health officials to monitor and respond to outbreaks effectively. By calculating the morbidity rate, health professionals can assess the risk and burden of a disease on a population and implement appropriate preventive measures.
