Are pathogens bad?

Yes, because they all cause diseases

100

How do viruses commonly spread?

They can be spread by coughing/sneezing, or through touch.

100

This type of transmission occurs when pathogens are carried through the air by tiny droplets released when an infected person coughs, sneezes, or talks.

Airborne transmission

How is cholera transmitted?

  • Contaminated Water: The most common mode of transmission is drinking water that has been contaminated with Vibrio cholerae, often from sewage or improper waste disposal.
  • Contaminated Food: Raw or undercooked seafood, especially from contaminated water sources, can also carry the bacteria.

This is one of the most common places for bacteria to spread.

What are pathogens?

A pathogen is a disease-causing organism.

A transmissible disease is a disease in which the pathogen can be passed from one host to another.

200

Bacteria is commonly spread by what?

Direct contact

200

Pathogens like norovirus and the common cold can spread through this, when an infected person touches surfaces and a healthy person touches the same surface.

Fomite transmission

What are the symptoms of cholera? (Name at least 3)

  • Severe watery diarrhoea
  • Vomiting
  • Thirst
  • Dry mouth
  • Decreased urine output
  • Fatigue
  • Muscle cramps
  • Sunken eyes and cheeks
  • Shock
200

This common method involves washing your hands with soap and water to prevent the transmission of pathogens from surfaces to your body.

Hand hygiene (Which some of you do not do properly)

About how many pathogens can fit on the eye of the needle?

Around a million

300

What is a transmissible disease?

A transmissible disease is a disease in which the pathogen can be passed from one host to another.

300

These organisms, such as mosquitoes and ticks, transmit diseases like malaria and Lyme disease through this type of transmission.

Vector-borne transmission

300

How do you treat cholera?

  • Oral Rehydration Solutions: A mixture of water, salt, and sugar, which helps replace the fluids and electrolytes lost due to diarrhea and vomiting.

  • Intravenous (IV) Fluids: For patients who are severely dehydrated and unable to drink, IV fluids may be required.

  • Antibiotics

  • Let them pass on peacefully (optional)

300

To prevent airborne transmission of respiratory diseases, health experts recommend wearing these to reduce the spread of droplets

Masks

Are pathogens the newest type of life form or the oldest?

The oldest.

400

How is protozoa commonly spread?

Contaminated Food & Water

400

This type of transmission involves consuming water contaminated with pathogens, causing diseases like cholera and typhoid.

Waterborne transmission

400

How does one prevent cholera?

  • Access to Clean Drinking Water

  • Improved Sanitation 

  • Food Safety

  • Vaccination

Bacteria cannot be seen by the naked eye. What equipment was used to see it?

Microscope

What is a virus?

The smallest possible pathogens that can infect you and make you sick.

500

List four ways of transmission.

Direct contact, Indirect contact, Contact with animals or insects, and contaminated food or water.

500

Contaminated food can transmit diseases like E. coli and salmonella through this type of transmission.

Foodborne transmission

What is the History of Cholera?
(You want a 500 question? Thought it was easy? Well take it)

It originated in the Indian sub-continent, in a nutshell

500

These can be used to sanitise surfaces and kill pathogens to prevent fomite transmission.
