What can pollution do to humans?
Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease.
Where are water borne diseases most common?
This waterborne disease is shared through contaminated water, most often in ponds and streams, but it can also be found in a town’s water supply, swimming pools, and more. The infection is caused by a parasite and typically clears up after a few weeks.
What are the factors affecting transmission of water borne diseases?
Lack of clean water supply, sanitation and hygiene (WASH) are major causes for the spread of waterborne diseases in a community. The fecal–oral route is a disease transmission pathway for waterborne diseases. Poverty also increases the risk of communities to be affected by waterborne diseases.
What diseases are caused by pollution?
The most common diseases caused by air pollution include ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer and acute lower respiratory infections in children. Particulate air pollution has been linked with strokes, which occur when the blood supply to the brain is cut-off.
What is meant by vector-borne diseases?
Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies.
How are disease spread through water?
Waterborne illness is caused by recreational or drinking water contaminated by disease-causing microbes or pathogens. Of note, many waterborne pathogens can also be acquired by consuming contaminated food or beverages, from contact with animals or their environment, or through person-to-person spread.
How can we prevent water borne?
Here are several ways to prevent water-borne diseases:
- Drink only filtered/boiled water.
- Store water in a clean container,
- Water jars/containers should be washed daily.
- Always wash hands before and after preparing food or eating, likewise, children should be taught on hand washing.
How can we prevent vector-borne diseases?
1. Ensure your vaccinations are up to date for diseases prevalent in the area. 2. Wear light-coloured, long-sleeved shirts and long trousers, tucked into socks or boots, and use insect repellent on exposed skin and clothing to protect yourself from being bitten by mosquitoes, sandflies or ticks.

What are water borne diseases and examples?
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 diseases are caused by poor hygiene?

What are three water borne diseases?
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.
Which disease is caused by air pollution?
Long-term ambient air pollution exposure was reported to increase all-cause mortality (10). Air pollution is the cause and aggravating factor of many respiratory diseases like chronic obstructive pulmonary disease (COPD) (11,12), asthma (12,13), and lung cancer (14,15).
How can we prevent water borne and vector-borne diseases?
Prevention of Food and Water Borne Illness
- Use good environmental management.
- Practice good personal hygiene.
- Take food safety precautions to learn about the fundamentals of food safety so that you can protect yourself, your friends, family and people in your community.
- Drink properly treated water.

Number of cases of vector-borne disease U.S. 2018, by disease. In 2018, there were around 23,558 confirmed cases of Lyme disease, making it the most common vector-borne disease in the U.S. Lyme disease is transmitted to humans through ticks.
Why Pollution is bad for your health?
The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt.

Is virus a pathogen?
All viruses are obligate pathogens as they are dependent on the cellular machinery of their host for their reproduction. Obligate pathogens are found among bacteria, including the agents of tuberculosis and syphilis, as well as protozoans (such as those causing malaria) and macroparasites.
How can we prevent vector-borne diseases Class 9?
Vector-Borne diseases can be prevented in the following ways:
- Vaccines should be developed for protection against disease-causing viruses.
- Insect repellants such as DEET or Permethrin can be applied to the skin and clothes respectively.
- Tick checks should be performed after exposure to dogs, cats, cattle, and mice.
Is Hepatitis A vector-borne disease?
Transmission. The virus is acquired through close contact with infected individuals or through faecally contaminated food or drinking-water. There is no insect vector or animal reservoir.
Why are water borne diseases a problem?
Waterborne diseases are caused by a variety of microorganisms, biotoxins, and toxic contaminants, which lead to devastating illnesses such as cholera, schistosomiasis and other gastrointestinal problems.
Are humans vectors for disease?
Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people. Humans can also be vectors for some diseases, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant.
