What are the symptoms of virus infection in human body

Thousands of viruses exist in our nature, and there are also some viruses present on the surface of the human body, such as on the human hands, feet, and so on. But most of the viruses do not do any harm to human beings, and only very few of them can cause you to get sick.

If the virus that invades the human body is one that has already invaded the human body, and there are still antibodies in the human body, then from the moment it invades the human body, the antibodies will combine with the virus and organize the virus to enter the cells to infect the human being, and then the macrophages will devour them. But if a new virus arrives in the body, because the body's immune system doesn't recognize the virus, they can evade the immune system's scrutiny and get inside the cell through receptor proteins on the cell membrane.

Once inside the cell, the viruses show their destructive side, utilizing the cell's original "factory" and directing the proteins inside to assemble their offspring. When the cell is filled with a large number of viruses, the virus will dissolve the cell membrane and continue to infect the next cell. After the virus has infected enough people, the body's immune system responds by sending out immune cells to clean up the mess.

When people are infected by a virus, some have mild symptoms that do not develop into serious illnesses and can be cured, while others can develop serious illnesses or even die. This is mainly due to differences in the strength of individual immunity. Our immune system protects the body from infection. While it works effectively most of the time, for some time the immune system malfunctions causing us to get sick.

Acquired immunity is the natural protection we are born with and is our first line of defense against infection. Upon detecting an infection, our innate response acts quickly to expel the invader by producing extra mucus or activating a thermostat to burn heat. Adaptive immunity is the protection we gain throughout our lives as we are exposed to disease or immunized with vaccines.

The efficiency of the adaptive response can be accelerated by vaccination. Vaccines cause the adaptive system to remember the intruder so that when it comes back the next time, the adaptive system can act quickly to attack. Secondly, with no vaccine yet available, the best thing we can do on a daily basis to boost your adaptive immunity is to adopt healthy living strategies.

To summarize, the human body is infected with a virus, some people have mild symptoms some people have moderate symptoms, is determined by the body's immune system. Some people are in good health, the immune system is relatively good, so mostly mild symptoms, on the contrary, poor health easily develop will be severe
