What is the Official Name given by WHO (World Health Organization) to Swine Flu?

  1. Influenza A virus subtype H1N1

  2. North American influenza

  4. H1N1 flu
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

WHO officially named the 2009 pandemic virus 'Influenza A (H1N1)' - not 'H1N1 flu' or just 'North American influenza'. The parenthetical (H1N1) specifies the subtype. 'Influenza A virus subtype H1N1' is overly verbose and not the official designation format.

A Correct answer
Explanation

Tamiflu (oseltamivir) can indeed be taken with or without food, giving patients flexibility in administration. Food does not significantly affect its absorption. The other options are incorrect - there's no requirement to take it before, after, or strictly separated from meals. This flexibility improves patient compliance.

The Centre for Disease Control, United States, and doctors in Washington recommend use of N95 respirators for protection. What is this N95 indicates?

  1. . It was the name given by Alexander von Humboldt who introduced it as his 95th design.

  2. It is a codename given by the company which manufactured it for the first time in 1995.

  3. This is a rating, which means the mask will filter at least 95% airborne particles.

  4. The nickname the mask obtained when it was continuously sold for 95 cents in USA.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

N95 refers to the mask's filtration efficiency - it filters at least 95% of airborne particles 0.3 microns or larger. The 'N' stands for 'Not resistant to oil'. This is an established NIOSH (National Institute for Occupational Safety and Health) rating system, not a nickname, codename, or person's name.

A country with more than 15000 confirmed cases of H1N1 pandemic in the year 2009 has surprisingly not even a recorded a single death due to the pandemic. Which country are we referring to?

  1. South Africa

  2. Germany

  3. Thailand

  4. Australia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Germany had over 15,000 confirmed H1N1 cases in 2009 but recorded zero deaths, an unusually favorable outcome attributed to excellent healthcare, early detection, and possibly the demographic profile of those infected. This stood out as remarkable compared to other countries with similar case numbers.

What is the size of H1N1 influenza virus?

  1. 30-80 nanometer

  2. 80-120 nanometer

  3. 120-150 nanometer

  4. 150-170 nanometer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

H1N1 influenza virus is approximately 80-120 nanometers in diameter, which is typical for influenza viruses. This size range is consistent with orthomyxoviridae family characteristics. The other options are either too small or too large for influenza particles.

To which group of medicines does the influenza medicine RELENZA belong?

  1. Analgesic inhibitors

  2. Neuraminidase inhibitors

  3. Anabolic stimulants

  4. Analgesic stimulants
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Relenza (zanamivir) belongs to the neuraminidase inhibitor class of antiviral drugs, which work by blocking the neuraminidase enzyme that viruses need to spread. This is the correct mechanism of action for influenza treatment. Analgesics are pain relievers, while anabolic stimulants are performance enhancers - neither describes Relenza's action.

Three of the leading Indian manufactures are striving to make the swine flu vaccine within the country. Which is the fourth odd one which does not belong to this list?

  1. Panacea Biotec, Delhi

  2. Serum Institute of India, Pune

  3. Cipla laboratories, Mumbai

  4. Bharat Biotech, Hyderabad
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cipla was the correct answer because during the 2009 H1N1 swine flu pandemic, Serum Institute, Bharat Biotech, and Panacea Biotec were actively involved in vaccine development efforts, while Cipla's focus was primarily on manufacturing antiviral drugs like oseltamivir rather than vaccine production. This made Cipla the 'odd one out' in the context of vaccine manufacturing.

In the name of swine flu virus H1N1 what does H and N stands for?

  1. Haemoglobin, Nutrition

  2. Hemagglutinin, Neuraminidase

  3. Histones, Nucleosomes

  4. Hemocyanins, Neuroglobin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In influenza virus nomenclature, H stands for Hemagglutinin and N stands for Neuraminidase. These are two surface glycoproteins found on the virus. Hemagglutinin is responsible for binding the virus to host cells, while Neuraminidase helps release new viral particles from infected cells. The numbers (1 and 1 in H1N1) refer to specific subtypes of these proteins.
