Collins (1997) stated that Viruses are not true living cells and are much smaller than bacteria. Viruses are composed of a protein coating around genetic material (DNA or RNA) and are unable to reproduce unless they are inside a living cell. Viruses do not multiply in food. They do multiply in cells in various organs or tissues of the body. For example, Hepatitis A virus replicates in cells of the liver. It is quite difficult to isolate viruses on or in food. Normally, the best treatment for viral infections is allowing time (bed rest) for each individual's functioning immune system to combat the virus Viruses are much smaller in size. The viruses differ from bacteria are they cannot live outside without living host human or animals. The two important viruses are Hepatitis A virus and nor viruses
Illnesses caused by Viruses
The viruses' food borne disease differs from bacteria:
1) They can only multiply inside the living host
2) Viruses do not multiply in foods.
3) Viruses are usually transferred from one food

Handle foods properly
2. Cook the at recommended temperature
3. Avoid eating raw seafood's
4. Food handlers must practice good personal hygiene
5. Wash hands and fingernails properly
2- Norwalk Virus
Virus: Norwalk virus
Symptoms: nausea, vomiting, diarrhea, abdominal pain, headache, low grade fever
Food Sources: contaminated water, shellfish from contaminated, water, contaminated fruits and vegetables
Prevention: Cook foods to a proper temperature, practice good personal hygiene, wash hands and fingernails
3- Rota Virus
Virus: Cause diseases like Rota virus gastroenteritis
It is the leading cause of severe diarrhea among infants and children.
Symptoms: vomiting, low grade fever, watery diarrhea
Transmission: person to person spread through contaminated hands
Prevention: Cook foods properly, practice good personal
Unlike bacteria, that have everything it needs to reproduce, viruses need to use a living cell's organelles in order to replicate.
We hear how Henrietta’s cells helped learn and find cures about so many viruses, but what is a virus? A virus is a microscopic organism that only replicates within the cells of a host organism. One of the most well known viruses Henrietta’s cells helped us with was the polio virus. Polio virus is a viral infection of your central nervous system. Polio virus is a lytic virus meaning that, polio goes through reproduction and the cells bursts. Polio virus’s most extensive outbreak was in the early to mid-1990s. Thankfully the vaccine was released in 1995.
Viruses - are extremely small particles made from protein and either DNA or RNA. They are not made up of cells instead they invade the living cells of other organisms and use them to produce many copies of
Not washing your hands, not wearing PPE, not storing or cooking foods properly, to cleaning your surroundings, not covering your nose or mouth when sneezing or coughing.
Viruses are microscopic organisms that can only replicate inside cells of the host organism. Viruses for the most part are so small you would have to use a conventional optical microscope. Viruses can infect any and all types of organisms, such as animals (to include Humans), plants and even bacteria as well as archaea (archaea constitutes a domain or kingdom of single-celled microorganisms). There are millions of different types of viruses. With viruses being believed to be the most abundant type of biological entity, they can be virtually found in every ecosystem on the planet.
Follow Hand Hygiene measures set by the CDC and WHO: Using the CDC and WHO guidelines to improve proper hand hygiene. This will reduce the health care related infections and reduce the transmission of disease from staff to patients (The Joint Commission, 2012)
A virus is a small nucleic acid molecule that can only multiply within a living cell of the actual host. It can produce a copy of that specific virus at an alarming rate. They are becoming more dangerous today. We need to build a better knowledge base to educate healthcare professionals and parents that bacteria and viruses are two different animals. Giving an antibiotic for a virus is not going to help; it will eventually cause antibiotic resistance. With viruses, the symptoms just need to be managed with over the counter medication, rest, and letting it run its course.
After looking at many articles I believe that viruses are not alive. Even though in the beginning I believed they were. For an object to be alive it needs to have certain characteristics such as being able to: grow, develop, have a purpose, reproduce, adapt, and have cells. A living thing could reproduce which means they would make offspring. Viruses don't have the ability to grow and develop on their own. Viruses don’t have the ability to reproduce on their own without the help of a keeper
There are many debates on whether viruses are living or nonliving cells. Viruses are organisms that infect living cells around its area. The characteristics of life describe a living cell and viruses only exemplify a few of those things such as adapting to their environment and containing a well-organized system. While viruses do portray some characteristics of life, they don’t reproduce, grow/develop, or display metabolism. Based on these viruses are not living.
Two ways that I could help prevent pathogens from spreading on a daily basis include avoiding close contact with people who are infected with a communicable disease and also by keeping my environment clean, by emptying trash cans frequently and keeping them clean.
It is often argued whether viruses are living or not. Those who don’t believe that viruses are living generally base their opinion off of the fact that they do not follow the basic definition of “life”. They do not carry out life-sustaining functions on their own like normal organisms. On the other side of the argument, some believe that viruses are in fact, living beings, which is where I rest my opinion.
When we hear the word virus, we usually think of something that makes us sick. A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The viral genome provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. To fight viruses, we use vaccines. While some may infect a broad range, other viruses can only infect certain kinds of cells. Vaccines are made of inactive, dead or weakened virus cells or protein antigens that can no longer infect
The article first addresses the issue of whether or not to consider viruses as living. Although viruses used to be thought of as being biological chemicals due to the fact that they consist of nucleic acids
Wash your hands with soap and water before eating or handling food and after using the toilet.
Most people would say that there are two different versions of viruses. One version of viruses infects people's computers and completely ruins them (which personally happens to me way to often, by the way), but the other version of viruses is a lot more deadly. These viruses affect all sorts of living things and could cause them to get very sick. Viruses replicate themselves inside an organism's living cells and they then spread to other organisms. Viruses usually spread in a similar fashion to how if you have the flu and you cough on somebody, then they will get sick as well. According to a website called Virology Blog, we do not consider viruses to be living things because, quite frankly, viruses are passive and do not fit the definition
