Viruses can be transmitted in numerous ways, such as through contact with an infected person, swallowing, inhalation, or unsafe sex.
The external barriers, such as the skin and mucous membranes, are the first line of defense. Viruses can affect any part of the body or body system, and can cause infections such as the common cold, flu, gastroenteritis, chicken pox or herpes. The common cold is a frequently occurring viral infection and usually includes symptoms such as sneezing, stuffy nose, sore throat and coughing. The diagnosis of a viral infection is usually based on the physical symptoms and the history of the illness. Both viral and bacterial infections cause sickness; however, there is a difference between them.
To contract a bacterial infection, pathogenic bacterium must gain access into the body through contaminated water, cuts, or contact with an infected person or contaminated objects. Human cells are vulnerable to viruses, and when the body is exposed to viral particles, the immune system will try to destroy these particles and eliminate them from the system.
A lowered immune system allows the virus to more easily attach itself to available cells, often bringing about general symptoms such as fever, chills, and muscle aches.
Children often contract viral infections, as children spend time around other children who have colds, and this makes it more likely that the cold will be passed on to them. For younger children who cannot blow their nose, use a rubber suction bulb to suck drainage from both sides of the nose. Children older than four years of age may be able to suck on throat lozenges for sore throats.
Children should drink extra water, fruit juices, or soups- avoid giving milk to infants for congestion reasons. The best way of treating human viruses will depend on the strength of the individual’s immune system, their overall health status, age, the severity of the condition, and the type of viruses involved. Minor illnesses caused by viral infections usually only require symptomatic treatment, while more severe conditions may require advanced medical treatment and sometimes even life-long treatment.
It is important to remember that treating human viruses cannot be accomplished through antibiotics, and the unnecessary use of antibiotics can weaken the immune system, thus increasing the likelihood of contracting another infection.
Over-the-counter painkillers and anti-inflammatories such as paracetamol or ibuprofen can reduce symptoms and fever, but can also have side effects, especially with long-term or excessive usage. Antiviral medication and immune substances such as interferons and immunoglobulins are sometimes prescribed for more serious infections.
Antiretroviral therapy suppresses the replication of the human immunodeficiency virus (HIV), even if there are no symptoms. Meditation, psychotherapy, and counseling may be of benefit when there are long-term consequences and psychological implications.
Viral infections can last as long as two weeks, and after infection, it is important to get the immune system back on track. Maintain a healthy lifestyle by eating properly, obtaining sufficient rest and exercising regularly.
Wash your hands frequently and thoroughly – before cooking, eating or after visiting the toilet. Avoid contact with someone who has an illness that you may catch such as a cold, the flu, chickenpox, or measles. Practice good personal hygiene by showering or bathing every day, washing your hair, and trimming your nails regularly.
Brush and floss your teeth twice a day, and visit your dentist regularly to prevent infection and cavities.

Pop sponges and dish cloths into the microwave to disinfect them, as they harbor the most germs. Eat protein and cooked vegetables at least twice a day as this helps to rebuild the immune system.
Increase your intake of nutritional supplements to prevent infections by helping to eliminate toxic substances, improve digestion, and balance body chemistry.
Positive attitudes and healthy emotions also strengthen the immune system and help you to live longer and feel younger and healthier. Comments, forum posts, artworks, and other user-added content is the property of the Poster.

The exact symptoms that go along with a viral throat infection would vary depending on the cause and the severity of the infection but the common symptoms when connected to the flue include soreness, a cough, muscle aches and pains, and low-grade fever.A  If the infection were linked to the cold, the same symptoms would be likely but with the addition of a runny nose, swollen lymph nodes in the neck, or perhaps small white bumps on the tonsils, if applicable. Then, if the viral throat infection were connected to coxsackievirus, you would still have soreness, and fever, but also a nagging headache, soreness of the tongue and roof of the mouth, neck, stomach, arm, and leg pain, and diminished appetite.A  A viral throat infection and mononucleosis include intense fatigue lasting longer than one week, mid-grade fever, red spots on the roof of the mouth, swollen lymph nodes in the neck, light red rash on the chest, although it can affect the whole body, and if you still have your tonsils, a white coating or swelling. As you can see, time is the best treatment for a viral throat infection.A  However, if you should begin experiencing sweats, chills, or your fever goes up, if the lymph nodes become increasingly swollen, if you notice white spots or puss on the back of the throat or tonsils, or if you cannot swallow, you need to make a follow-up appointment with the doctor.

Viruses are made up of the genetic material known as DNA or RNA, which the virus uses to replicate. Factors such as poor hygiene and eating habits can increase your risk of contracting a viral infection.
The body’s immune defenses are triggered when the virus enters the body, and white blood cells (lymphocytes and monocytes) begin to attack and destroy the virus.
Although colds are a minor infection of the nose and throat, a cold can last from two days to two weeks. Stomach viruses can be spread through contaminated food or water and can cause viral gastroenteritis, meaning inflammation of the stomach and intestines (small and large).
Chickenpox is an infectious disease; with most cases occurring in children under age 15, but older children and adults can also get it. A condition such as influenza, which is caused by a virus, is generally easy to diagnose because most people are familiar with the symptoms. Symptoms may vary depending on what part of the body is affected, type of viruses, age, and overall health of the affected person. A viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria. One of the major differences between viral and bacterial infections is that a bacterial infection can be transmitted through inanimate objects such as door knobs and countertops, whereas viral cannot. This also makes it easier for the virus to replicate, and thus advances symptoms until the immune system can fight the virus off.

A child’s immune system is not as strong as adults, and their body is still learning how to fight viruses for the first time.
A combination of treatment options such as conventional medicine, complementary therapy, and natural medicine can help to fight the infection, control the symptoms, and strengthen the immune response. They can be administered orally, intravenously, intramuscularly, topically, or by inhalation. Eat foods rich in vitamins like oranges, carrots, kiwis, raisins, green beans and strawberries. Using condoms during sexual intercourse will reduce the spread of sexually transmitted diseases. Doctors use blood tests to diagnose hepatitis C infection, determine the best course of treatment and monitor its progress.
Colds are highly contagious and are spread by fluids from sneezing or coughing, which contain the infection. Improper hand washing following a bowel movement or handling a diaper can spread the disease from person to person. Oral herpes causes sores around the mouth and face, while genital herpes affects the genitals, buttocks and anus. Other types of viral infections may be harder to diagnose and various tests may have to be performed.
Viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes with its own. Another difference is that bacteria is a living microorganism and reproduces by dividing itself, while a virus will die if it does not have a host. Because viruses live within the body’s own cells, antiviral medications often have severe side effects.
Continue to drink plenty of fluids, and go easy on sweets, as they make the body acidic and pathogens thrive in this environment. Walking 20 minutes a day, without over-exertion, can help keep the body healthy and get back into optimum shape after a viral infection. Three common types of hepatitis C blood tests are antibody tests, genotyping and hepatitis C RNA.
Unlike many other viral respiratory infections, the flu can cause severe illness and life-threatening complications in many people.
Symptoms of gastroenteritis can include nausea with or without vomiting, diarrhea, low-grade fever and abdominal pain. Genital herpes is known as a sexually transmitted disease (STD) and it is transmitted through sexual contact through the mouth and genitals.
Viruses are not living organisms and need a "living" host in order to reproduce-otherwise it cannot survive.
Common bacterial infections occur due to the invasion of pathogenic bacteria through the respiratory or digestive tract.
Bacterial infections usually need to be treated with an viral infection or stop the spread of a viral infection to others. Many people call gastroenteritis the "stomach flu", although this virus is not a strain of Influenza at all. Taking care of the immune system after a virus will not only allow for prime health but will help keep new viruses at bay. The disease is usually mild and lasts 5 to 10 days, although adults and older children tend to get sicker from it. Like chickenpox, this virus will remain in the body forever; however, a person with herpes may continue to deal with reoccurrences or "outbreaks" for life. Chickenpox in a virus that stays in the body forever and in most cases a person who has had the virus will likely never contract it again.
