I received my order yesterday, which is FANTASTIC! I also wanted to say thank you. I sent an email to Ask our Experts, and I was surprised at the speed [of the response]. Thanks so much for the excellent service!

What is a Viral Infection?
A virus is a tiny organism that causes an infection in the body. Viruses are made up of the genetic material known as DNA or RNA, which the virus uses to replicate. In order for a virus to survive, it must invade and attach itself to a living cell. It will then multiply and produce more virus particles.
By attaching itself to a host cell, the virus may either kill or alter the cell’s functions. When the cell dies, new types of viruses are released, and they infect other cells. This is how viruses cause disease. Generally, viruses will only infect one type of cell. For example, the cold virus will only infect cells of the upper respiratory tract.
Viruses can be transmitted in numerous ways, such as through contact with an infected person, swallowing, inhalation, or unsafe sex. Factors such as poor hygiene and eating habits can increase your risk of contracting a viral infection.
The external barriers, such as the skin and mucous membranes, are the first line of defense. 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.
This type of general protection is referred to as innate or natural immunity.
Viruses can affect any part of the body or body system. The most common type of viral infections involve the respiratory tract. For example, the cold virus involves the upper respiratory tract, viral throat infections, and laryngitis. Lower respiratory tract infections may include viral pneumonia.
The gastrointestinal system is also commonly affected by viruses with symptoms such as diarrhea and/or vomiting. The liver can also be infected by viruses such as the hepatitis virus family.
The skin can also be infected by a viral infection such as the common wart or chicken pox. Nervous system viral infections include encephalitis and rabies.
Systemic viral infections can also occur with certain viruses or when replication of the virus in the body accelerates unchecked, and the virus affects multiple body systems. This can be an extremely dangerous condition and usually requires prompt medical attention. HIV is an example of a systemic viral infection.
Diagnosing Viral Infections
The diagnosis of a viral infection is usually based on the physical symptoms and the history of the illness. A condition such as influenza, which is caused by a virus, is generally easy to diagnose because most people are familiar with the symptoms. Other types of viral infections may be harder to diagnose and various tests may have to be performed.
What Causes Viral Infections?
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. This also makes it easier for the virus to replicate, and thus advances symptoms until the immune system can fight the virus off.
Help for Viral Infections
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. 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.
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.
