2 . The immune (免疫的) system has special defense and attack strategies reserved for viruses (病毒). These involve tagging the viruses with antibodies and killing cells infected (使感染) by the virus. A global health crisis can bring the world to its knees, highlighting the huge impact a virus can have. This tiny organism, invisible under a normal microscope, can wreak havoc on worldwide.

There are more viruses on Earth than stars in the universe, so why haven’t we always been maintaining social distance? Primarily because not all viruses can infect us, and for those that do, the body handles them quite well. To put it simply, viruses are extremely small parasites that infect all sorts of life, from the smallest bacteria to the largest mammals; they are considered parasites because they can’t survive by themselves. Viruses infect health y host cells and use their cellular “tools” to make more copies of themselves.

Viruses are everywhere—in the air we breathe, the water we drink, and the land on which we walk. Yet, even after being bombarded with viruses, our body still manages to stay strong. This is because of our immune system and its clever strategies to fight back against viral attacks! Fortunately, with our modern healthcare advancements, we have extra help to fight viruses. These include vaccines, antiviral drugs, and other health technologies to keep us going in this never-ending war.

As time goes by and our bodies encounter more viruses, we develop better immunological memory. This is the body’s way of remembering past infections, making it better prepared for future ones.
