Infectious Diseases Quiz & Flashcards

Tuberculosis is caused by bacteria, while the others are viral infections.

Vector-borne diseases are spread by organisms like mosquitoes and ticks.

The common cold is mainly spread through airborne droplets from coughs and sneezes.

Malaria is caused by protozoa, specifically Plasmodium species, transmitted by mosquitoes.

Rabies is a zoonotic disease, meaning it can be transmitted from animals to humans.

R0 indicates how many people, on average, one infected person will spread the disease to.

The misconception is that vaccines cause autism, which is not supported by scientific evidence.

Quarantine aims to prevent exposure by restricting the movement of those who may have been exposed.

Ringworm is caused by a fungal infection, unlike the other viral diseases listed.

Vaccines stimulate the immune system to recognize and fight pathogens without causing disease.

Cholera is often spread through contaminated water, unlike the other diseases listed.

Wearing masks helps prevent the transmission of respiratory droplets that carry pathogens.

Antimicrobial resistance occurs when microorganisms survive despite exposure to antibiotics.

Genetic predisposition can increase susceptibility, while the other options typically decrease it.

Isolation separates those who are sick, while quarantine restricts those exposed to prevent spread.

Patient zero refers to the first identified case in an outbreak, often used to trace the disease origin.

Genetic inheritance is not a mode of transmission for infectious diseases; it refers to genetic conditions.

Hepatitis B is caused by a virus, while the others are bacterial infections.

Climate change alters habitat ranges, potentially expanding the range of disease vectors.

Asymptomatic means an individual is infected but shows no symptoms, though they can still spread the disease.

Fever is a common symptom indicating the body's response to infection.

A pandemic spreads across multiple countries and affects a large number of people.

Vectors, like mosquitoes, carry pathogens and transmit them to hosts, aiding in disease spread.

A reservoir is an environment where a pathogen naturally lives and multiplies.

Contact tracing involves identifying and notifying individuals who may have been exposed to an infectious disease to prevent further spread.

The MMR vaccine is a live attenuated vaccine, meaning it uses weakened forms of the virus.

The incubation period is the time between exposure to a pathogen and the onset of symptoms.

Malaria is transmitted by mosquitoes, unlike the other diseases listed.

A superbug is a bacterium that has developed resistance to multiple antibiotics, making it difficult to treat.

Completing the full course of antibiotics helps prevent the development of antibiotic-resistant bacteria.

A fomite is a non-living object that can carry and transmit infectious pathogens.

Hepatitis A is typically transmitted through contaminated food and water, not vectors.

Herd immunity occurs when a large part of the population becomes immune, reducing the spread of disease.

Viruses require a host cell for replication, unlike bacteria, fungi, and protozoa.

Surface proteins help pathogens attach to host cells, facilitating infection.

Mosquitoes are the primary vectors for transmitting malaria.

An endemic is a disease regularly found in a certain area; an epidemic is a sudden increase in cases.

A nosocomial infection is acquired in a hospital setting, such as a urinary tract infection.

Tetanus is caused by bacteria, while the others are fungal diseases.

The immune system's primary function is to identify and eliminate pathogens that cause infectious diseases.

Probiotics help maintain healthy gut flora, which can inhibit the growth of harmful pathogens.

Influenza is caused by a virus, while the others are bacterial infections.

Sanitation reduces exposure to pathogens, lowering the risk of disease spread.

Scarlet fever is caused by bacteria, while the others are viral diseases.

Measles can be prevented by a vaccine, while the others currently have no effective vaccines available.

The overuse and misuse of antibiotics contribute to the development of antibiotic resistance.

Latent infections show no symptoms until the pathogen is reactivated.

A misconception is that infectious diseases only affect humans; they can affect animals and plants as well.

Antiviral drugs function by inhibiting virus replication, reducing the severity and duration of infections.

The main reason for quarantine is to prevent the spread of the disease within the community.
