Bacteria spread exclusively through air travel.

Bacteria spread only through sexual transmission.

Bacteria spread through direct contact, respiratory droplets, contaminated surfaces, and food or water.

Bacteria spread through insect bites and animal contact.

White blood cells primarily transport oxygen throughout the body.

White blood cells are responsible for producing hormones in the body.

White blood cells help in the digestion of food in the stomach.

White blood cells are essential for identifying and attacking pathogens in the immune response.

Handwashing

Avoiding crowded places

Using hand sanitizer

Wearing gloves

Virus

Bacteria

Fungi

Parasite

Pathogens can enter through skin contact with clean surfaces.

Pathogens can enter via sound waves and electromagnetic fields.

Pathogens can enter the human body through inhalation, ingestion, direct contact, and breaks in the skin.

Pathogens can enter through water absorption and sunlight exposure.

Bacteria are non-cellular and need a host to grow, while viruses can reproduce alone.

Viruses are non-cellular and require a host to replicate, while bacteria are single-celled organisms that can reproduce independently.

Viruses can be treated with antibiotics, whereas bacteria cannot.

Viruses are larger than bacteria and can survive without a host.

Herd immunity is the indirect protection from infectious diseases that occurs when a large percentage of a population becomes immune, thus reducing disease transmission.

Herd immunity is the direct protection from diseases that occurs when everyone in a population is vaccinated.

Herd immunity is the phenomenon where a small group of people becomes immune, leading to increased disease spread.

Herd immunity is the ability of a community to resist diseases without any immune individuals present.

Nausea, vomiting, and diarrhea

Chest pain, shortness of breath, and chills

Headaches, dizziness, and rash

Common symptoms of a viral infection include fever, fatigue, muscle aches, cough, sore throat, and runny or stuffy nose.

Vaccines cure diseases by directly attacking pathogens.

Vaccines help by eliminating all pathogens from the environment.

Vaccines help prevent diseases by training the immune system to recognize and fight pathogens.

Vaccines prevent diseases by providing instant immunity to everyone.

Antibodies function to identify and neutralize foreign objects like bacteria and viruses.

Antibodies store energy for the immune cells.

Antibodies are responsible for muscle contraction.

Antibodies help in the digestion of food particles.

Proper hygiene reduces the transmission of pathogens by removing or killing them, minimizing contact with contaminated surfaces.

Proper hygiene has no effect on pathogen transmission in public spaces.

Proper hygiene increases the spread of pathogens by creating a moist environment.

Proper hygiene only benefits personal health without affecting others.

Aspergillus niger

Rhizopus stolonifer

Penicillium chrysogenum

Candida albicans

The body forgets pathogens after a short period of time.

The body uses antibodies to destroy all pathogens immediately.

The body recognizes a pathogen it has encountered before through memory cells that retain information about the pathogen.

The body relies on enzymes to break down pathogens quickly.

Zoonotic diseases are human-made infections that affect animals and humans equally.

Zoonotic diseases are infections transmitted from animals to humans, often through direct contact, vectors, contaminated food or water, or aerosols.

Zoonotic diseases are primarily transmitted through human-to-human contact and not through animals.

Zoonotic diseases are only found in tropical regions and spread through air travel.
