  4. You will find more fecal bacteria in a shopping trolley at a supermarket store than you will find in a supermarket toilet. In a similar way, shopping bags that are reusable also have a very high amount of fecal bacteria present in them, unless they are regularly washed.
  5. All the cloth seats that you see on a public transport are home to an unimaginable number of bacteria as well as mold. The cloth seats are difficult to clean, and even if someone wipes them with alcohol swipes, it will only kill a nominal portion of the bacteria.
  6. When you use too many antibacterial products and cleaners, it only makes the germs more resistant. As a result, it gives rise to super bugs, viruses that are stronger and more resistant to products that could originally kill them.

23 Fun Facts About Virus For Kids:

      1. If you take into account each milliliter of seawater, you will find at least a million different virus particles. It means that if you line up the total number of virus, the resulting line would stretch for about 200 million light years into space.
      2. The word virus comes from the Latin language, where it means something that is like a slimy liquid or is poisonous.
      3. In the year 1901, a man named Walter Reed discovered the first human virus, which was the yellow fever virus.
      4. A virus does not have any form of energy or any carbon metabolism. It is not a living entity, and cannot replicate or grow. In fact, a virus is an inanimate and complex form of organic matter, which can only be evolved within a cell.
      5. Almost half of the total DNA of all humans has originally come from viruses. These viruses infected the human eggs and sperm cells and then embedded themselves inside them.
      6. Not all viruses are harmful. For instance, there are certain viral proteins that help to prevent the immune system in a pregnant woman from attacking the fetus.
      7. While most viral infections do not cancer, there are some types of viruses that do lead to cancer. Some types of cancers, such as cervical cancer, liver cancer, Burkitt’s lymphoma, Kaposi sarcoma and T-cell leukemia originate from various viral infections.
      8. A virus can attack almost any living thing that it comes in contact with. As a virus can have rapid genetic diversion, it is easier for it to infect any type of living organism. A virus can infect human beings, animals, birds, plants, insects, bacteria, amoeba, fungi, protozoa and even other types of viruses.
      9. One of the first available proof of a viral infection dates back as far as 3700 B.C. The documentation shows a patient who seems to be infected with a classic case of poliomyelitis. It is a type of infantile paralysis, also known as polio, which is caused by an infectious disease by the poliovirus.
      10. Based on their genetic makeup, viruses are classified as DNA (Double Strand Nucleic Acid) or RNA (Single Strand Nucleic Acid) virus. Out of the two types of viruses, the DNA virus is more stable. At the time of replicating, it can replicate better as per its genetic material. As a result, it is easier for doctors to create vaccines that will be effective against the DNA virus. The RNA virus is less stable and when it replicates, its genetic material changes very fast. As a result, doctors find it hard to come up vaccines that will be effective against the RNA virus.
      11. While most viruses are harmful, they do also have some use in the medicinal world. Doctors are using viruses for gene therapy to help with gene delivery system. It can help to treat various acquired as well as inherited diseases.

As a result, your body does not recognize it immediately and is not able to fight it off. It leads to recurring bouts of infection from the same virus.
      15. If you count each organism on this planet, there are at least ten or more viruses for each one. Till date, scientists have found at least 4000 different types of viruses on this planet.
      16. Did you know that on an average, the life span of a virus depends on the type of temperature it is placed in? For instance, a virus can live for a few seconds in a temperature of 370 degree C, for a few minutes in a temperature of 200 degree C, for about an hour in a temperature of 100 degree C, for a few days in a temperature of zero degree C, and for a number of years when the temperature is below minus degree.
      17. In most cases of viral infections, antibiotics do not help to treat the same. In fact, most viral infections, such as cold, flu or even some types of chest infections will get better on their own without the need of any medication. In fact, the immune system of the host body will help attack and remove the virus on its own.
      18. If a person gets infected with the EBV (Epstein Barr Virus) once, he or she will become a carrier for life. However, it does not mean that the person will always show symptoms of the same. According to some estimates, almost 50 percent children in the USA have been affected with the EBV and that almost 90 to 95 percent adults are carriers.
      19. One of the biggest known viruses till date is the mimivirus, which is about 400 nanometers (approx. 0.0004 millimeters) in diameter. The smallest known virus is the circovirus, which measures about 20 nanometers (0.00002 millimeters) in diameter.
      20. When you are affected with cold or cough, the virus particles present inside can travel a distance of up to 320 km an hour and up to a distance of 900 meters. It is in fact faster than the speed at which a passenger jet travels at the time of takeoff.
      21. Till date, scientists have found about 300 different types of viruses that can cause a host of fatal diseases in insects. Surprisingly, these viruses are completely different from the viruses that cause illness in human beings. While they may be fatal to the insects, these viruses are not at all harmful to humans.
      22. A virus can only reproduce and evolve when it is in a cell inside an animal or in a plant.
      23. While viruses can certainly cause various health scares, there are some that are very useful for human beings. A certain type of virus, known as the bacteriophages, which also translates to ‘bacteria eater,’ helps to kill the bacteria. This type of virus is used to keep human beings protected against any harmful effects from the bacteria that are present in food.

10 Fun Facts About Yeast:

      1. There are about 500 different species of yeast that are known to exist today. Each species further has thousands of different strains, which means that every specie and strain is somehow unique.
      2. Yeasts are different from each other in terms of what they can do. For instance, those who want to bake will use a specific baker’s yeast, while those who want to brew any alcoholic beverage will use that specific type of yeast.
      3. Yeast live best in liquid and moist environments and not in dry environments.
      4. While using a recipe that involves yeast, you have to let the mix rest for about a few hours or even a day. This is because the time allows the yeast to eat. As the yeast eats, it uses up different elements in the ingredient mix to give you the specific type of result you want from the recipe.
      5. Yeasts do not require sunlight as a source of energy but use the various organic compounds to give them energy.
      6. When the temperature in a fermentation process rises up, it leads to the growth of more yeast.
      7. It is very difficult to kill yeast. You can try to dry it, freeze it and even starve it, but the moment it comes in contact with the tiniest amount of water or moisture, or any smallest amount of sugar, it will grow back again.
      8. Sometimes, yeast can simply give up in the middle of something it is doing. For instance, if you are using yeast for fermentation, it may suddenly decide to not help with the process and quit. This is also referred to as a stuck fermentation.
      9. You can actually find yeast everywhere around you. From being present in the air, to being present on your keyboard, to your hair and skin, it is almost everywhere and almost completely surrounds you.
