Understanding the Flu Virus

The flu is a highly contagious respiratory illness caused by the influenza virus, leading to significant annual deaths and historical pandemics. The virus, a mutating parasite, uses proteins to infect hosts and evade eradication. It exists in various strains, with Type A being the most pandemic-prone. Historical pandemics like the Spanish flu highlight its deadly potential. Ongoing monitoring and vaccine development are crucial for prevention.

What is the primary characteristic of the flu virus that makes it a recurring health issue?

• It is a highly contagious respiratory illness.

• It is easily treatable with antibiotics.

• It only affects animals.

• It is a bacterial infection.

What are the two proteins used by the flu virus to infect host cells?

• Hemagglutinin and Neuraminidase

• DNA and RNA

• Antibodies and Antigens

• Lipids and Carbohydrates

How does the immune system respond to the flu virus?

• By ignoring the virus

• By bombarding the viral swarm and destroying infected tissue

• By producing more red blood cells

• By increasing body temperature

Why is the flu virus difficult to eradicate?

• It can mutate rapidly.

• It is not contagious.

• It is resistant to all medications.

• It only affects a small population.

Which type of influenza virus is most capable of causing a pandemic?

• Type B

• Type C

• Type A

• Type D

What is a notable characteristic of Type A influenza viruses?

• They can cross species barriers.

• They are resistant to vaccines.

• They do not mutate.

• They are only found in humans.

What was the global impact of the Spanish flu pandemic?

• It had no significant impact.

• It was easily contained.

• It infected a third of the global population and killed millions.

• It affected only a small region.

What is the origin of the H1N1 strain of the flu virus?

• It originated from fish.

• It was discovered in plants.

• It likely came from birds.

• It was first found in reptiles.

What is the current strategy to combat the threat of influenza pandemics?

• Ignoring the virus

• Developing seasonal vaccines

• Relying solely on natural immunity

• Using antibiotics

What role do scientists play in managing the flu virus?

• They monitor the virus and develop vaccines.

• They ignore the virus.

• They only study the virus in animals.

• They focus on other diseases.
