There is a very long-standing relationship between human beings and virus that wander unreservedly in our environment. Virus has a long history of disconcerting people. 
A virus is a microorganism that is not visible to the naked eye. It is highly contagious and communicable. In humans, a virus attacks by attaching to a living cell of the human body. It then discharges its DNA or RNA, which alters the original genetic material and functioning of the cell. It may lie dormant in the cell for quite some time before causing it to rupture and release more viral particles into the cellular space. Each new particle can repeat the same activity and ultimately wreak havoc in the body. Once the virus has multiplied using cellular mechanics, it can impede the growth and working of other healthy cells too.
This can be extreme enough to force the entire body into a vulnerable (sickened) state. However, the immune system of the body enacts its best defenses against the viral invasion. As we know, the immune system does not succeed in all the cases. Due to this reason, it is always best to maintain a healthy lifestyle rich with nutritious food and healing herbs that strengthen the resistance of the body.
The Residence and Transmission of Virus
There are different types of viruses known. Some infect humans, plants or other animals and a few affects both human and animals. Viruses are everywhere in our surroundings. They can be transmitted via the food we eat, air we breathe, water we drink, injection from needles, or sexual contact etc.
Respiratory Viruses
Respiratory viruses are a group of viruses that affect the respiratory system. These include influenza virus, respiratory syncytial virus, parainfluenza virus, and adenovirus.
It is important to remember that having severe underlying health conditions can make it much more difficult to fight off viral invaders. One example of an underlying condition is when a flu virus seriously affects people who have asthma or other chronic lung diseases. For this and other reasons, some people may be at a higher risk of developing complications from the flu when compared to a healthy person.
How can you prevent having to battle respiratory viruses?
In many cases, the flu can be prevented with proper handwashing, distancing from others who are ill, and avoiding immunosuppressive foods (i.e., sugars). Many people trust vaccinations because they believe this will prevent sickness with a respiratory virus. Other have found success with powerful natural supplements that keep them from developing flu-like symptoms.
What do we advise? Pay attention to what you are eating and drinking and pursue nutrition that is immune-boosting, rather than immune-taxing. We will soon publish an article on the top 10 immune boosting foods. They compliment natural regimens like Elderberry consumption (which elevates Vitamin C levels and helps protect the body from developing flu and cold symptoms), or (if used preventatively) can help avoid suffering altogether. We discussed this topic briefly in another post that talks about the upcoming winter season.
