Directly kill invading bacteria
Which description best defines a pandemic, as seen with COVID-19?
A foodborne illness at one restaurant
A disease outbreak across many countries
A chronic condition in one person
A seasonal infection in one city
Which pair correctly matches disease with its transmission focus?
Pneumococcus—non-living rocks
Influenza—respiratory droplets
Influenza—genetic inheritance
Pneumococcus—ultraviolet light
Which practice helps limit antibiotic resistance in communities?
Completing prescribed antibiotic courses
Using antibiotics for viral colds
Stopping antibiotics when symptoms start
Sharing leftover antibiotics widely
Which statement about vaccines and white blood cells is accurate?
Vaccines replace natural immune organs
Vaccines stimulate cells to produce antibodies
Vaccines cure infections immediately
Vaccines directly destroy harmful bacteria
A student groups conditions as infectious: influenza, pneumonia, Covid-19, malaria; non-infectious: asthma, diabetes, osteoporosis, dust allergy. Which statement best evaluates this classification?
It is correct for all listed conditions
It mislabels Covid-19 as non-infectious
It mislabels asthma as infectious
It mislabels influenza as non-infectious
Which pair lists examples of pathogens?
Genes and alleles
Cholesterol and fats
Bacteria and viruses
Smoke and pollutants
Which situation most likely describes a non-infectious disease?
Fever caused by a viral outbreak
Flu contracted from a classmate
Condition inherited from both parents
Illness spread by contaminated water
Community leaders plan to reduce infections spread by contaminated water. Which action is most appropriate for this route of transmission?
Boil or chlorinate the water supply
Encourage handshakes at ceremonies
Use thicker winter clothing outdoors
Increase indoor crowding at events
A town has repeated cholera cases linked to street food. Which plan would most effectively reduce transmission?
Promote daily outdoor exercise routines
Enforce safe water and food handling
Increase mask use in all public areas
Encourage outdoor dining for all meals
Which scenario best describes droplet transmission of an infectious disease?
Touching a clean metal surface
Sharing sealed bottled water
Talking closely without masks indoors
Sitting alone in a large park
Which symptom is most characteristic of influenza compared with pneumococcal pneumonia?
Abrupt high fever with myalgia
Gradual productive cough onset
Localized chest pain only
Persistent diarrhea without fever
Which sign more strongly suggests pneumococcal pneumonia than uncomplicated influenza?
Lobar consolidation on chest imaging
Sneezing with watery nasal discharge
Diffuse muscle aches without cough
Loss of smell without lung findings
Which statement best contrasts viral and bacterial causes in these diseases?
Both are protozoal; treatment is antiparasitic
Both are viral; antibiotics are always used
Influenza is viral; pneumococcal disease is bacterial
Influenza is bacterial; pneumococcal disease is fungal
Which statement best explains the role of masks during respiratory outbreaks?
Masks reduce droplet spread between people
Masks only protect against insect bites
Masks cure viral infections completely
Masks replace the need for vaccines
A patient has influenza caused by a virus. Which treatment choice is most appropriate and why?
Antibiotics, because they kill all microbes including viruses
Antivirals, because they target viral replication specifically
High-dose antibiotics, because resistance slows viral growth
No medication, because viruses always resolve without treatment
Misuse of antibiotics can lead to resistant bacteria. Which practice most accelerates this process?
Taking probiotics after finishing antibiotic treatment
Using antibiotics for viral illnesses like influenza
Combining vaccines with antibiotics during outbreaks
Completing the full prescribed antibiotic course
What is a key component contained in vaccines to build immunity?
Only vitamins and mineral salts
An agent resembling the pathogen
A high dose of broad antibiotics
Pure white blood cells for defense
A patient with suspected pneumococcal pneumonia asks for antivirals. What is appropriate?
Say vaccines cure active bacterial disease
Suggest antivirals work better for bacteria
Explain antibiotics treat bacterial infections
Recommend no medication is ever required
What is the immediate goal of vaccination schedules in a community?
Ensure every illness shows mild symptoms only
Build population immunity and reduce transmission
Replace all treatments with preventive herbs
Eliminate the need for handwashing forever
