Which of the following diseases spread through contaminated food and water?

The pathogens of most interest to us are Salmonella, Shigella, E. coli, Listeria and Hepatitis A-all of which can be transmitted by food, water and/or dairy products. For more information about our foodborne illness investigation, foodborne disease epidemiology and consulting services please contact us.

Is Diarrhoea is a waterborne disease?

Each year, waterborne diseases afflict hundreds of millions of people, primarily those living without safe, accessible water in developing countries. Of the seven most common waterborne diseases in the world, diarrhea is the central symptom.

What is an example of a waterborne disease?

Contagion by pathogenic microorganisms Some waterborne pathogenic microorganisms spread by water can cause severe, life-threatening diseases. Examples are typhoid fever, cholera and Hepatitis A or E. Other microorganisms induce less dangerous diseases. Often, diarrhoea is the main symptom (figure 1).

What are examples of a pathogen?

• Zika virus.
• HIV.
• hepatitis C.
• polio.
• influenza (flu), including H1N1 swine flu.
• Dengue fever.
• Ebola.
• Middle East respiratory syndrome (MERS-CoV)

Which of the following is not transmitted through contaminated water?

Complete answer: Diphtheria is an infection that begins with a sore throat or fever and can become severe in some cases. This is caused by a bacterium named Corynebacterium diphtheria and can transmit through the air or by direct contact with the patient. It doesn’t spread through contaminated food or water sources.

What are 3 bacteria examples?

Examples include Listeria monocytogenes, Pesudomonas maltophilia, Thiobacillus novellus, Staphylococcus aureus, Streptococcus pyrogenes, Streptococcus pneumoniae, Escherichia coli, and Clostridium kluyveri.

How does water become contaminated by pathogens?

The sources of coastal water contamination are: point discharges of treated and untreated sewage from shoreline outfalls, and non-point discharges. The non-point sources, such as runoff from naturally vegetated areas, discharge pathogens into coastal waters.

What bacteria is found in stagnant water?

Nocardiosis. Nocardia species are gram-positive bacteria that are found in soil and stagnant water and although they predominantly cause disease in immunocompromised individuals, a third of cases of nocardiosis cases occur in immunocompetent individuals (Beaman and Beaman, 1994).

Which of the following is spread through water?

The result: dangerous diseases like cholera and typhoid fever. Other waterborne diseases include diarrhoea, dysentery, polio and meningitis. Unclean water for washing can cause skin and infectious eye disease such as Trachoma.

What is the most significant route of pathogen transmission?

Oral (Ingestion) Transmission The ingestion of pathogenic organisms can occur from contaminated food or water as well as by licking or chewing on contaminated objects or surfaces. Environmental contamination is most commonly due to exudates, feces, urine, or saliva.

Can pathogens live in water?

Water, a frequent vehicle for the transmission of viruses, may permit their survival, but many environmental factors will have an adverse effect on the viral population. Risk evaluation requires identification of these factors and assessment of the inactivation rate of infectious viruses.

Is influenza A waterborne disease?

Air Borne and Water Borne Diseases The relevant pathogens may be viruses, bacteria, or fungi. Many common infections can spread by airborne transmission are tuberculosis, influenza, small pox. Waterborne diseases are caused by pathogenic microorganisms and most commonly transmitted through contaminated fresh water.

Is measles a waterborne disease?

The viral infection is transmitted mainly through ingestion of contaminated water or food or through direct contact with an infected person. Many of the drinking water pipes were found to have been damaged in the floods. Negative pressure could lead to contamination of the water being distributed through pipes.

What happens if you drink contaminated water?

If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.

How are diseases spread by contaminated food and drink?

There is a wide range of infectious diseases that are transmitted by contaminated food and water. Many are caused by pathogens (bacteria, viruses or parasites) transmitted via the faecal-oral route (consumption of food and drinks contaminated with faeces).

Which of the following diseases is spread by both contaminated food and contaminated water class 8?

Question 5: Which two diseases are caused by contaminated food and water? Answer: Cholera and Diarrhoea / Dysentery.

What are two examples of infectious diseases a food handler may carry that can contaminate food?

Such illnesses include gastroenteritis (often called ‘gastro’) – including viral gastroenteritis (norovirus or rotavirus) – hepatitis A and hepatitis E, sore throat with fever, and fever with jaundice.

What are the 4 types of pathogens?

Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms.

What are the three types of pathogenic bacteria?

• Mycobacterium tuberculosis: Tuberculosis.
• Escherichia coli: Bloody diarrhea.
• Vibrio cholerae: Cholera.
• Clostridium botulinum: Botulism poisoning, paralysis.
• Streptococcus pneumoniae: Pneumonia, meningitis.
• Staphylococcus aureus: Skin infection.

What are the 6 types of pathogens?

Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions.

What is an example of a foodborne infection?

The most common foodborne infections are caused by three bacteria — Campylobacter, Salmonella, and E. coli O157:H7 — and by a group of viruses called calicivirus, better known as Norwalk-like virus: Campylobacter — Campylobacter is the most common bacterial cause of diarrheal illness in the world.

What are non infectious diseases give examples?

Non-infectious diseases are not caused by pathogens and therefore cannot be spread from one person to another. Instead, non-infectious diseases are caused by factors such as genetics, malnutrition, environment and lifestyle. Examples of non-infectious diseases include cancer, Alzheimer’s disease and epilepsy.
