What have this special God created microorganism , we call it virus... has done to us? ..
A few viral diseases which students should know are:
1. Rubella
Rubella virus is the pathogenic agent of the disease Rubella, and is the cause of congenital rubella syndrome when infection occurs during early pregnancy, and can cause foetal death..
2. AIDS-an Immune System Disease caused by HIV which affects the immune system and your health, and your immune system will be seriously damaged.

3. SARS- The SARS coronavirus, sometimes shortened to SARS-CoV, is the virus that causes severe acute respiratory syndrome (SARS).

4. Poliomyelitis (polio) is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours.

5. Hepatitis A virus (HAV) is a faecal-oral pathogen and transmission is particularly associated with faecally contaminated food and water. ...
6. H1N1-Swine-flu
SCIENTISTS today warned of a deadly new flu virus which has become resistant to drugs.
The H1N1 "A" virus is a strain that causes common seasonal flu outbreaks.
But it carries an altered gene that makes it resistant to certain drugs.
Doctors fear it could seriously threaten hospital patients with weakened immune systems.
Prevention & Treatment:What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against novel H1N1 virus. There are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza.
Take these everyday steps to protect your health:
· Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
· Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
· Avoid touching your eyes, nose or mouth. Germs spread this way.
· Try to avoid close contact with sick people.
· Stay home if you are sick for 7 days after your symptoms begin or until you have been symptom-free for 24 hours, whichever is longer. This is to keep from infecting others and spreading the virus further.
What is the best way to keep from spreading the virus through coughing or sneezing?
If you are sick, limit your contact with other people as much as possible. If you are sick, stay home for 7 days after your symptoms begin or until you have been symptom-free for 24 hours, whichever is longer. Cover your mouth and nose with a tissue when coughing or sneezing. Put your used tissue in the waste basket. Then, clean your hands, and do so every time you cough or sneeze.

What should I do if I get sick?
If you live in areas where people have been identified with novel H1N1 flu and become ill with influenza-like symptoms, including fever, body aches, runny or stuffy nose, sore throat, nausea, or vomiting or diarrhea, you should stay home and avoid contact with other people. Staying at home means that you should not leave your home except to seek medical care. This means avoiding normal activities, including work, school, travel, shopping, social events, and public gatherings
· If you have severe illness or you are at high risk for flu complications, contact your health care provider or seek medical care. Your health care provider will determine whether flu testing or treatment is needed
· If you become ill and experience any of the following warning signs, seek emergency medical care.

Emergency warning signs that need urgent medical attention include:
· Difficulty breathing or shortness of breath
· Pain or pressure in the chest or abdomen
· Sudden dizziness
· Confusion
· Severe or persistent vomiting
· Flu-like symptoms improve but then return with fever and worse cough
CDC recommends that people with novel H1N1 flu avoid contact with others as much as possible. They should stay home from work or school for 7 days after the onset of illness or until at least 24 hours after symptoms have resolved, whichever is longer.
Contamination & Cleaning
How long can influenza virus remain viable on objects (such as books and doorknobs)?
Studies have shown that influenza virus can survive on environmental surfaces and can infect a person for up to 2-8 hours after being deposited on the surface.
What kills influenza virus?
Influenza virus is destroyed by heat (167-212°F [75-100°C]). In addition, several chemical germicides, including chlorine, hydrogen peroxide, detergents (soap), iodophors (iodine-based antiseptics), and alcohols are effective against human influenza viruses if used in proper concentration for a sufficient length of time. For example, wipes or gels with alcohol in them can be used to clean hands. The gels should be rubbed into hands until they are dry.
What surfaces are most likely to be sources of contamination?
Germs can be spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air. Germs can be spread when a person touches respiratory droplets from another person on a surface like a desk, for example, and then touches their own eyes, mouth or nose before washing their hands.
How should waste disposal be handled to prevent the spread of influenza virus?
It is recommended that tissues and other disposable items used by an infected person be thrown in the trash. Additionally, persons should wash their hands with soap and water after touching used tissues and similar waste.
What household cleaning should be done to prevent the spread of influenza virus?
It is important to keep surfaces (especially bedside tables, surfaces in the bathroom, kitchen counters and toys for children) clean by wiping them down with a household disinfectant according to directions on the product label.
How should linens, eating utensils and dishes of persons infected with influenza virus be handled?
Linens, eating utensils, and dishes belonging to those who are sick do not need to be cleaned separately, but importantly these items should not be shared without washing thoroughly first. Linens (such as bed sheets and towels) should be washed by using household laundry soap and tumbled dry on a hot setting. Individuals should avoid “hugging” laundry prior to washing it to prevent contaminating themselves. Individuals should wash their hands with soap and water or alcohol-based hand rub immediately after handling dirty laundry.
Eating utensils should be washed either in a dishwasher or by hand with water and soap.
