Yes because of thebacteria- basically germs that make you sick. that's why people tell you to wash your hands because of all the bacteria(germs) that will make you sick
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.
Disgusts keep us away from things that could make us ill. Rotten things that are decaying contain microbes and many of these can cause diseases. They kill millions of people and make billions of others sick.
Bacteriophages can be useful for targeted bacterial infection treatment, known as phage therapy. They can also be used in food safety to kill harmful bacteria, in bacterial detection methods, and as tools for genetic engineering and biotechnology research.
Breathing in the ozone layer, which is primarily found in the stratosphere, would not make you terribly ill or kill you as it is too high in the atmosphere to be inhaled directly. However, exposure to ground-level ozone, which is a pollutant formed closer to the Earth's surface, can cause respiratory issues and other health problems over time.
Bacterial vagnosis isn't a germ that originated in one place and traveled to another. It's an imbalance in the normal bacteria of the vagina, with an overgrowth of bacteria that are normally found in the rectal area.
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.

Because you have aids
Well, you can get ill from depression.
You should worry about catching chlamydia if you are having sex. Over 2.25 million people in the US are infected with the bacteria. It is the #1 bacterial STD infection in the US.
vaccinations are tiny amounts of the bacteria you are trying to be immune to. Your body attacks these tiny amounts and recognises their 'DNA' so if you get that disease or infection your body knows what it is looking for and can target it more easily.
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.
Because it is cold which gives us sore throats etc
Pathogenic viruses cause illnesses and disease.
Because the skin has it's own natural flora or bacteria to it which compete with other bacteria to keep us healthy. That's why when you get a cut you're more at risk for infection because the skin barrier has been breached.
Chlamydia is the most common bacterial STD in the US and Canada. In the US, 50% of women will have had the infection by the time they're 30 years old; it is likely that the rates in males are the same. About 3-6% of the US population is infected at any one time. The chances of getting chlamydia from an act of vaginal sex are between 40 and 60%. See related links for references.There is not data to answer your question, but chlamydia is the #1 bacterial infection, infecting in the US 1.25 million people per year (reported; so the actual number is higher as some have no symptoms hence they don't know they are infected).
