An episode of an infectious disease that spreads worldwide is known as a: ?
Correct Answer
A. Pandemic
Explanation
A pandemic refers to an episode of an infectious disease that spreads globally, affecting a large number of people in multiple countries or continents. Unlike an epidemic, which is confined to a specific region or population, a pandemic is characterized by its widespread nature. An outbreak, on the other hand, refers to the occurrence of cases of a particular disease in a specific community or area, but not necessarily on a global scale. Endemic refers to a disease that is constantly present in a particular region or population.
3.
What chance does a healthy person have of getting the flu during an average year?
Correct Answer
A. About 75 percent
Explanation
The correct answer is "Less than 2 percent." This is because a healthy person has a lower risk of getting the flu compared to individuals with weakened immune systems or underlying health conditions. The flu is primarily transmitted through close contact with infected individuals, so maintaining good hygiene practices and getting vaccinated can further reduce the chances of getting the flu.
4.
Which of the following common symptoms is not usually a feature of flu in adults?
Correct Answer
A. Chills and a high fever
Explanation
Chills and a high fever are usually common symptoms of the flu in adults. The flu typically presents with symptoms such as muscle aches and pains, a runny nose, sore throat, and cough. Vomiting and diarrhea are not typically associated with the flu in adults.
5.
How long after exposure to the influenza virus do people develop symptoms?
Correct Answer
A. 24 hours
Explanation
After exposure to the influenza virus, people typically develop symptoms within 24 hours. This is because the influenza virus has a short incubation period, meaning it takes a relatively short amount of time for the virus to replicate and cause symptoms in the body. Symptoms may include fever, cough, sore throat, body aches, and fatigue. It is important to note that the exact timing of symptom development can vary from person to person, but 24 hours is the most common timeframe.
6.
Which of the following is a way in which flu can be spread?
Correct Answer
A. Droplets in the air that are breathed or sneezed out
Explanation
Flu can be spread through droplets in the air that are breathed or sneezed out. When an infected person coughs, sneezes, or talks, tiny droplets containing the flu virus are released into the air. These droplets can then be inhaled by others who are nearby, leading to the spread of the flu. This is why it is important to cover your mouth and nose when coughing or sneezing, and to maintain good respiratory hygiene to prevent the transmission of the flu virus.
7.
Is your taste unaffected during flu?
Correct Answer
B. No
Explanation
During a flu, our taste buds can be affected due to congestion or inflammation in the nasal passages, which can lead to a reduced ability to taste and smell. This can result in a diminished sense of taste and affect our ability to enjoy food and beverages. Therefore, the correct answer is "No" as our taste is indeed affected during flu.
8.
During a case of the flu, which of the following is a sign you need to see a doctor urgently?
Correct Answer
A. Dry cough
Explanation
A dry cough during a case of the flu can be a sign that you need to see a doctor urgently. While a dry cough is a common symptom of the flu, it can also be a sign of a more serious respiratory condition, such as pneumonia. Pneumonia is a potential complication of the flu and requires medical attention. Therefore, if you experience a dry cough during the flu, it is important to seek urgent medical care to rule out any complications and receive appropriate treatment.
9.
What is the best time of the year for a person to be vaccinated against influenza?
Correct Answer
A. In autumn, just before the peak flu season
Explanation
The best time for a person to be vaccinated against influenza is in autumn, just before the peak flu season. This is because the vaccine takes about two weeks to provide full protection, so getting vaccinated before the flu season starts ensures that the person is protected when the virus is most likely to be circulating. Additionally, getting vaccinated in autumn allows for enough time for the immune system to build up immunity before the peak flu activity occurs.
10.
Does flu diminish your sense of smell?
Correct Answer
A. Yes
Explanation
Influenza, commonly known as the flu, can indeed diminish a person's sense of smell. This is because the flu virus can cause inflammation and swelling in the nasal passages, which can interfere with the ability to detect and perceive odors. Additionally, congestion and mucus buildup can further contribute to a reduced sense of smell. It is not uncommon for individuals with the flu to experience temporary anosmia, the partial or complete loss of smell. Therefore, the answer "Yes" is correct.
