How is dengue fever transmitted?
- A.
Bite of an infected mosquito
- B.
Bite of an infected male Aedes mosquito
- C.
Bite of an infected female Anopheles mosquito
- D.
Bite of an infected female Aedes mosquito
Correct Answer
D. Bite of an infected female Aedes mosquitoExplanation
Dengue fever is transmitted through the bite of an infected female Aedes mosquito. Male mosquitoes do not transmit the virus, and neither do female Anopheles mosquitoes. It is important to note that only female Aedes mosquitoes are capable of transmitting the dengue virus, making them the primary vector for the disease.Rate this question:

Incubation Period refers to
- A.
Time between exposure and onset of symptoms
- B.
Time between appearance of symptoms and recovery phase
- C.
Time between exposure and course of illness
- D.
Time between febrile phase and critical phase
Correct Answer
A. Time between exposure and onset of symptomsExplanation
The incubation period refers to the time between exposure to a pathogen or a disease-causing agent and the onset of symptoms in an individual. During this period, the pathogen is multiplying within the body, but the person does not yet show any signs or symptoms of the illness. This period can vary depending on the specific disease and can range from a few hours to several days or even weeks. Understanding the incubation period is crucial in identifying and controlling the spread of infectious diseases.Rate this question:

- A.
High fever
- B.
Rash
- C.
Petechiae
- D.
Severe GI bleeding

D. Severe GI bleedingExplanation
Severe GI bleeding is a sign under the critical phase of the disease.Rate this question:

Dengue fever incubation period ranges from:
- A.
1-12 days
- B.
3-14 days
- C.
14-28 days
- D.
28-32 days
Correct Answer
B. 3-14 daysExplanation
The correct answer is 3-14 days. The incubation period for dengue fever refers to the time it takes for symptoms to appear after a person has been infected with the virus. This period can vary, but typically ranges from 3 to 14 days. During this time, the virus replicates in the body and the person may not experience any symptoms. After the incubation period, symptoms such as high fever, severe headache, joint and muscle pain, and rash may occur. It is important to note that some individuals may experience a longer incubation period, up to 14 days, before symptoms appear.Rate this question:

To prevent fluid overload, what type of diuretic should be given to the patient?
- A.
Loop diuretic
- B.
Potassium-sparing diuretic
- C.
Osmotic diuretic
- D.
None of the above
Correct Answer
A. Loop diureticExplanation
Loop diuretics are the most appropriate type of diuretic to give to a patient in order to prevent fluid overload. Loop diuretics work by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys, leading to increased urine production and fluid loss. This is particularly effective in conditions such as heart failure or kidney disease, where there is excessive fluid accumulation in the body. Potassium-sparing diuretics, on the other hand, help to retain potassium and are not as effective in preventing fluid overload. Osmotic diuretics are used to increase urine production in specific situations such as reducing intracranial pressure, but they are not typically used to prevent fluid overload.Rate this question:

What are the 3 phases of Dengue fever?
- A.
Coalescing, trivial and serious
- B.
Staging, growing and spreading
- C.
Febrile, Critical, and Convalescent
- D.
None of the above
Correct Answer
C. Febrile, Critical, and ConvalescentExplanation
The correct answer is Febrile, Critical, and Convalescent. Dengue fever is characterized by three distinct phases. The febrile phase is the initial stage, during which the infected person experiences high fever, severe headache, joint and muscle pain, and rash. The critical phase follows, where the fever subsides but can lead to complications such as plasma leakage, organ impairment, and even death. Finally, the convalescent phase occurs, where the symptoms gradually improve, and the patient recovers. These three phases are crucial for understanding the progression and management of Dengue fever.Rate this question:

Which mosquito species are primarily responsible for Dengue fever?
- A.
Aedes albopictus
- B.
Anopheles gambiae
- C.
Aedes aegypti mosquito
- D.
Culiseta annulata
Correct Answer
C. Aedes aegypti mosquitoExplanation
Aedes aegypti mosquitoes are primarily responsible for Dengue fever. This species of mosquito is known to transmit the Dengue virus to humans through its bites. They are commonly found in tropical and subtropical regions and are known to breed in stagnant water sources near human habitation. Aedes aegypti mosquitoes are also responsible for transmitting other diseases such as Zika, Chikungunya, and Yellow fever.Rate this question:

Which of the following is a symptom of Dengue?
- A.
Fever
- B.
Rash
- C.
Sever muscle and joint pains
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the listed options are symptoms of Dengue. Dengue is a viral infection transmitted by mosquitoes. One of the main symptoms is a high fever, which is often accompanied by other symptoms such as a rash and severe muscle and joint pains. Therefore, all of the given options are correct and can be considered as symptoms of Dengue.Rate this question:

Which of the following are the diagnostics methods for dengue?
- A.
RT–PCR
- B.
Nucleic acid amplification tests (NAATs)
- C.
Enzyme-linked immunosorbent assays (ELISA)
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
RT-PCR is a diagnostic method for dengue. It stands for reverse transcription-polymerase chain reaction and is used to detect the presence of dengue virus RNA in a patient's blood. RT-PCR is a highly sensitive and specific method that can accurately identify the virus during the early stages of infection. Nucleic acid amplification tests (NAATs) are also diagnostic methods for dengue, which include RT-PCR. Enzyme-linked immunosorbent assays (ELISA) are another diagnostic method that detects the presence of dengue virus antibodies in a patient's blood. Therefore, the correct answer is "All of the above" as all three methods are used for diagnosing dengue.Rate this question:

Which of the following are important for dengue prevention?
- A.
Using mosquito repellents
- B.
Going outside in the evening
- C.
Keeping the doors and windows open
- D.
All of the above
Correct Answer
A. Using mosquito repellentsExplanation
Using mosquito repellents is important for dengue prevention because it helps to repel mosquitoes, which are the primary carriers of the dengue virus. Mosquito repellents contain ingredients that are effective in keeping mosquitoes away, reducing the risk of being bitten and infected with the virus. By using mosquito repellents, individuals can protect themselves and minimize the chances of contracting dengue.Rate this question:
