Many dangerous viral strains have been found to originate in China jumping from birds or pigs to the human population. Birds alone have been found to carry as many as 15 viral strains. A virus has no cell membrane, no metabolism, no respiration and cannot replicate outside of a living cell. Once inside, it reprograms the cell with its DNA or RNA and multiplies on mass, bursting through the cell with a thousand or more new virus strands seeking new cells to invade.
If two viruses invade the same cell a bird virus and a human virus, for instance their DNA can combine to form a new virus, a potentially virulent one. The same is true if two animal viruses combine and jump species to humans.
In the lytic cycle, the virus focuses on reproduction. It invades a cell, inserts its DNA and creates thousands of copies of itself, bursts through the cell membrane, killing the cell, and each new viral strand invades new cells replicating the process. In the lysogenic cycle, viruses remain dormant within its host cells. The virus may remain dormant for years. Herpes and chickenpox are good examples.
Chicken pox can cause shingles in later life when the dormant virus reactivates. Our bodies fight off invading organisms, including viruses, all the time. Our first line of defense is the skin, mucous, and stomach acid. If we inhale a virus, mucous traps it and tries to expel it.
If it is swallowed, stomach acid may kill it. If the virus gets past the first line of defense, the innate immune system comes into play. The phagocytes wage war and release interferon to protect surrounding cells.
If they cannot destroy the invading force, the phagocytes call the lymphocytes into play. Our lymphocytes, T cells and B cells, retain a memory of any previous infection that was serious enough to bring them into the battle.
Antibodies were formed and the body knows how to fight any infection it recognizes. This is how vaccinations work. The body has fought a similar infection.
But viruses can mutate, sometimes so much that they body cannot recognize them as a similar infection they fought in the past. They can also be so fast acting, they can kill before the lymphocytes are brought into play. Antiviral medications do not directly kill the virus; they trap it within the cell, keeping it from reproducing. They kill bacteria, not viruses. And they kill good bacteria that we need to keep our gut in balance.
Taking antibiotics when you have a viral infection can cause an immediate overgrowth of Candida, giving the immune system an additional system-wide infection to deal with when it needs all of its resources to fight a viral infection. Conventional treatment is supportive treatment—fluids, medications for symptoms such as asthma medication , but no medications have ever been developed to kill the virus itself.
But still, it brings up a point. Viral infections are a symptom of a weak immune system. Your immune system is wholly dependant on your gut health.
A sick gut has an abundance of fungi and other pathogens, and a healthy gut has a wide variety of beneficial bacteria. The supplements listed below are a half measure. A healthy nutrient dense diet, a healthy lifestyle, and a body void of as many toxins as possible is the first and foremost defense.
If you want to skip the shortcuts and truly fortify your immune system, read the following articles:. The object is known as a fomite.
Viruses often change over time. Some of these changes are very small and do not cause concern, but others can be more significant. Significant changes could make a virus more transmissible, as has been the case with the B. They may also help the virus evade the immune system or existing treatments. For example, doctors use several drugs in combination to treat HIV so that it is harder for the virus to develop resistance to treatment. Influenza viruses can also do so-called antigenic shift.
This can happen if a host cell has become infected with two different types of influenza virus. For instance, pigs can often serve as a mixing vessel for avian and human influenza viruses.
Some viruses, such as HPV, can lead to cancer. The full impact of a virus can take time to appear, and sometimes there may be a secondary effect. For example, the herpes zoster virus can cause chickenpox.
The person recovers, but the virus may stay in the body. Years later, it may cause shingles in the same individual. Coronaviruses are a large family of viruses and include viruses that cause the common cold. However, it has changed many times since scientists first identified it in China.
By September , scientists had logged over 12, mutations, and the development continues. Some variants are more transmissible and more likely to cause severe illness than others. The main concern with new variants is the unpredictability of their impact. The main symptoms of COVID are dry cough , fatigue , and fever, but there are many possible symptoms. Anyone who has symptoms should seek a test. It is also important to self-isolate until 10 days after symptoms appear and when no fever has been present for 24 hours.
If a person has difficulty breathing , they should seek emergency medical attention. However, special T cells, known as cytotoxic T cells, can recognize cells that contain viruses, and release substances that kill those cells. Some viruses can escape detection by cytotoxic T cells, but other immune cells — natural killer cells — can cause the cell containing the virus to die.
In addition, body cells that contain a virus emit proteins called interferons, which warn other cells that a virus is present. This gives healthy cells a chance to defend themselves by changing the molecular makeup of their surface. Antibodies can also help fight a virus before it enters a cell. They do this by neutralizing or damaging the virus or by changing its features so that it can no longer enter healthy cells.
Antibiotics treat bacterial infections , but they cannot treat a viral infection. People will need either a vaccination to prevent infection, or antiviral drugs to treat any symptoms. Sometimes, the only option is symptom relief. In recent decades, scientists have developed antiviral drugs, largely in response to the AIDS pandemic. These drugs do not destroy the virus, but they slow or prevent its development.
With antiviral treatment for HIV, for example, the level of virus in the body can become so low that tests cannot detect it. At this point, it becomes untransmittable, which means that a person cannot pass the virus on to another person. Antivirals are also available to treat infection with HSV, hepatitis B , hepatitis C , influenza, shingles, and chickenpox.
Tamiflu is an example of an antiviral drug. People can use it to manage influenza. Researchers conducted the same test with the swine flu virus and the findings revealed that all 4 herbal drinks can inactivate over 99 per cent of the swine flu virus in hardly 5 minutes.
This novel study is quite helpful for all of us when it comes to preventing the fatal infection. All you can do is to gargle or rinse your mouth with green tea daily or consume it along with other juices mentioned above. Take enough precautions and keep yourself safe.
