Pathogenic viruses cause illnesses and disease.
By reproducing and multiplying rapidly. and they make us ill by attacking our cells and converting their normal functions to producing the virus.so they get your own cells to do their dirty work too (this applies for viruses)
Viruses make us feel ill by invading our cells and causing damage to our tissues. This triggers an immune response that can lead to symptoms such as fever, muscle aches, and fatigue as our body fights off the infection. Additionally, the toxins produced by viruses can contribute to the symptoms of illness.
no
Because you have aids
Well, you can get ill from depression.
Any microorganism can make us ill once it colonizes. For example, on your skin right now are varieties of bacteria along with yeast. This normal flora does not make us ill (usually). But if something gets out of balance, the bacteria or yeast can begin to multiply. Our bodies initially try to wall off the infection if it is inside our bodies; on the skin, it is harder. If our defenses are low or we cannot fight it off, an infection is well underway.
Toxins can be produced by certain bacteria and viruses to cause illness in humans. Bacteria such as Clostridium botulinum produce botulinum toxin, while viruses like influenza can produce proteins that exacerbate symptoms such as fever and muscle aches. These toxins can disrupt normal bodily functions and lead to symptoms of illness.
In general, microorganisms that can make you sick are termed "germs" by the non-medical world. Bacteria that can cause disease or sickness are termed "pathogens." There are way too many to list here and certain strains of microorganisms can be harmful while other strains of that same organism may not be.
Viruses make us sick by invading our bodies and hijacking our cells to replicate themselves. This process can damage our cells and tissues, leading to symptoms of illness as our immune system responds to the infection.
Because it is cold which gives us sore throats etc
cross contamination/infection is never good, but the very young and the elderly have weaker immune systems so the infections that just make us a little ill can make them very ill. The illnesses that make us very ill can very likely kill them.
The song you are referring to is "Unstoppable" by Sia. The lyrics you mentioned are from the chorus of that song.
