Hello my friend......
Finally you reached to the most important site which is "Environmental Health".
Oh I forgot to introduce my self I am DR.Cleany I think my name is not strange for you, you may heard it with my friends Droppie, Airy and Mariam I hope you enjoyed your time with them
Now, it is my turn to tell you in simplified way about these diseases.....
And I will begin with diseases that result from air pollution ...
Of course you knew that there are two types of air pollution chemical and biological. One of the things that result from chemical pollution is carbon monoxide poisoning.
**Carbon monoxide is one of the gases that come out from car exhausts or from cigarette smokes. Many people confuse between carbon monoxide and carbon dioxide.
The effects of carbon monoxide are quite different from those of carbon dioxide, when oxygen and carbon monoxide enter the blood stream they compete for haemoglobin of the blood the power of carbon monxide to combine with haemoglobin is greater than that of oxygen.This combination forms a new product called carboxyhaemoglobin, as this product increases the oxygen supply in the blood decreases, and so vital blood tissues are robbed of their need of oxygen.with time damage occur to the heart, blood vessels, and other organs.
Symptoms of carbon monoxide poisoning include headache, dizziness, and nausea.Respiration becomes difficult and the victim yawns frequently. Recent studies show that even short term exposure to the carbon monoxide can be harmful. And people already suffering from heart or lung diseases can experience different types of physical distress when exposed to carbon monoxide and that is one of the dangers of chemical pollution of air.
Another thing is carbon dioxide that cause suffocation after it has replaced oxygen in closed area and this lead to carbon dioxide narcosis which has very bad effect on the human body's system that may cause decrease the concentration of the person and so it will definitely lead to decrease the reaction time.of -course my friend you will ask what is the reaction time ??
It is the time that the person need to give his reaction to an act and to make it clear I will give you example :
If one drives his car, when he sees car move towards so his reaction-normally- will be quick and fast to avoid the accident as his concentration is high and he doesn't need much time to think about what he sees and what he should do....
But if there is much carbon dioxide in his car -for example because he smokes lot in closed car- his reaction time will increase and he will need much more time to think about what he sees and what he should do!!!
And that is the danger of increase of carbon dioxide, and many things occur as result of the chemical pollution of air..
Now it is time to tell you about air-borne infections . Bacteria and viruses that infect the nasal passages ,sinuses, throat, trachea and lungs are present in saliva and mucus. A sneeze or a cough sprays a mist of germ-laden droplets into the air, and this is a serious health problem. In nearly every public place ,people cough and sneeze, filling the air with droplets of their saliva for others to inhale .
Any way I will tell you about some of them like influenza, measles, mumps, and smallpox that has been successfully eradicated.
I think you heard lot about influenza .......it is really dangerous if it is not treated well. It is caused by a virus that spread by droplets and contact with contaminated articles.It usually affect the respiratory passages or gans. Its symptoms
|are fever,weakness,ache in back and limbs and sore throat,but if it is not treated in proper way or if the treatment is neglected it will lead to serious and bad effects, it may even lead to pneumonia.|
So, it must be treated seriously by taking rest and drinking fluids and many other things that sure you know. Of course all doctors how to find vaccines to influenza to protect people from its dangers .......one of the hopes in this world.
The next disease that we will talk about is measles that is also caused by virus which is transmitted through droplets, nasal discharge and contact with contaminated articles.nAnd it usually affects the upper respiratory tract.While its symptoms are fever, cough, red and swollen eyes, rash spreading from face to body, and koplik's spots in mouth.And to treat it well the patient should have bed rest, protection of the eyes, and taking antibiotics to prevent complications, but this disease has vaccine. Few cases may be attack by it even if they took the vaccine.
There is another type of measles called German Measles that is also caused by virus and it spreads in the same way, but it affects the respiratory passages or gans. And its symptoms are quite different here the patient suffer from fever, swollen glands, rash resembling scarlet fever. And the best treatment is bed rest till the rash has faded.
And now we will talk about mumps, this disease is caused by virus and spreads through droplet infection and direct contact with contaminated articles it mainly affects the parotid gland which is one of the salivary glands. Its symptoms are swelling of parotid glands and complications, and it may have serious complication if it is not treated well .The best treatment is by local applications of gamma globulin.
And the last one I will tell you about is chicken pox which is a virus transmitted by direct contact to droplets or air-borne or by indirect contact to the soiled articles.It affects the whole body and skin,its symptoms can be known easily:mild fever, weakness, skin eruption in different stages at the same time.And this can be treated by relief of itching, prevention of infection and scarring of pustules.
finally I can't say that these are the whole diseases that are transmitted through air but these are the most serious and important. I think you knew enough about these diseases and now its role to think how to help our friend Airy......
For me I think it is time to go to the next page and know the diseases that result from water pollution....Do not you think so my friends??!!
So Let's Go......... Next Page
