Viruses (biological)
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses display a wide diversity of shapes and sizes, called morphologies. Generally viruses are much smaller than bacteria. Most viruses that have been studied have a diameter between 10 and 300 nanometres.

Viruses do not really "eat" because they are not alive. They are called microbes and microscopic organisms by some scientists for ease of discussion, but they don't meet the strict definitions of these, so other scientists prefer to call them "sub-microscopic infectious agents".
They carry pieces of DNA or RNA and attach to and enter a living host's cells (plant or animal) and cause those cells to create more viruses. The virus causes this replication by modifying the DNA of the "invaded" host cells to make them stop their original function in the host and turn into a cell functioning only to reproduce copies of the virus. The material and energy needed to reproduce them is not coming from the virus or to the virus in the form of food, it is provided by the host animal's or plant's cells. Viruses can not continue to replicate (stay "alive") without the host cell doing the work and providing the materials.
Resting would be better since your body is already stressed while fighting the flu and you will put unnecessary strain on your systems if you do strenuous activities. Jogging and other exercises that cause perspiration are also not a good idea when you are experiencing symptoms of a disease that can cause fever and dehydration. Take a short break from the exercise and rest in bed for the fastest way to get over the flu.
How do viruses reproduce compared to bacteria?
Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host.
A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more detail of the process of reproduction of some viruses inside body cells.
Can the flu cause a miscarriage?
No it doesn't cause a miscarriage. But it does make you hypertensive I believe the long phrase is. You will need to be put on drip in a and e to keep fluid wise down. I'm a nurse and at risk of getting norovirus and I know for a fact it doesn't cause a miscarriage. Miscarriages occure when the fetus has chromosone abnormalities really early on in pregnancy.
The term virus stands for vital information resources under seize. And it can be created by using infected files on your pc. And it can fastly destroy you computers, you will not be able to open your files which are effected by these viruses. And it effects from one computer to another computer.
Can you have mononucleosis and the flu at the same time?
Yes, in fact sometimes the flu causes laryngitis. Laryngitis is a symptom of the inflammation of the vocal cords and can be caused by many things including the flu, a common cold, being "hoarse" from yelling, emotional stress, etc. Resting your voice and gargling with salt water often helps.
Does the rabies virus have an envelope?
Yes, Rabies virus has an envelope of host plasma membrane origin which is embedded with the sole virus spike protein - Glycoprotein.
Can you get rabies from a wild bird?
"Rabies has been produced in birds experimentally, however, it has never been found in wild bird populations."
Birds have been found to have positive titers for rabies: (Gough & Jorgenson, "Rabies antibodies in sera of wild birds". JOURNAL OF WILDLIFE DISEASES, Vol 12, July 1976.

What is the effect of viruses in the human?
it depend on type of vruses and their tropism.Flue viruses it afect cells in our larinx and the sympoms are very knowed for us.In other hand Hiv it infect our imunity cell bringin the organizm in a state of imunity deficence.A lot of people that have aquired hiv have problems with infection due to low number of leucocytes that are destroyed by hiv viruses.
What type of virus infects t cells?
HIV The human immunodeficiency virus is a lentivirus that causes HIV infection and acquired immunodeficiency syndrome
Like all influenza viruses it has a roughly spherical shape.
How does rabies cause fear of water?
Hydrophobia (fear of water) is a classical sign of terminal rabies infection. This isn't a true "fear" but is rather a reasonable response to the lack of control over the mouth and throat - drinking water could result in aspiration of that water into the lungs, a painful and potentially lethal problem.
Why is chicken pox virus not considered a living thing?
Viruses are considered to be non-living and because they are not alive, they can not reproduce. A better term is to replicate or make a copy of themselves. It is like using a copy machine.
Is a virus or yeast the biggest microorganism?
Generally speaking, the virus is a smallest living organism that consists of one DNA strand (or RNA), tightly wrapped in protein and lipids (fat molecules). Of course, some species of virus are larger than others. Nevertheless, a viral organism consists of a relatively limited amount of molecules, and it is ABSOLUTELY without a cellular structure and void of any cellular components. It can ONLY replicate inside a living cell. It is a parasitic organism by nature, and in order for it to complete its life cycle, it must utilize cellular structures of another organism. A virus cannot replicate independently. There is even a debate among microbiologists, as to whether or not it can meet the definition of life. Yeast, on the other hand, is a species of fungi. It can be unicellular (one cell) or can form multicellular clusters. Regardless, even unicellular yeast organism is BY FAR larger than any given viral particle.
A virus is NOT a life form. It is NOT living in any sense. Viruses are much smaller than yeast.
What are the description stage of dengue fever?
Stage 1: Acute fever and upper respiratory symptoms
· Stage 2: Fever subsides
· Stage 3: Circulatory failure, neurological problems, and hemorrhaging
· Stage 4: Shock and death (10% of all cases reach this stage)
How is the Human Coronavirus transmitted?
The CDC and researchers worldwide still have a lot to learn about COVID-19 and how it spreads. According to current knowledge, though, the coronavirus that causes COVID-19 is mainly spread from person to person through respiratory droplets. That means droplets from an infected person’s coughs and sneezes land on other people’s noses or mouths, or they breathe them in, and that infects them, too. It’s also possible that the virus can spread through people touching contaminated objects and then touching their mouth, nose, or eyes.
For more information on this ever-developing situation, consult the CDC’s page dedicated to COVID-19, found here.
Covid-19 is really a firing question for every one today. But I think instead of thinking about do i have it or not or when vaccine will arrive, we must prepare for it and only strong immunity is the solution so far I found.
But any way you can click the link below and view my expertise about how to fight off corona-virus:
Was there a vaccine for the flu of 1918?
At the time electron microscopes didn't exist so most Doctors and scientists thought the 1918 "Spanish" H1N1 flu was a bacteria. This was due to finding the lungs of victims in autopsies full of bacteria which they had the technology to isolate.
In 2005 scientists isolated the H1N1 Influenza A of the 1918-1919 pandemic. So they could manufacture a vaccine based on that virus-I'm not aware if this has been done.
What are the signs and symptoms of rabies?
Malaise, fever and headache are early stages of rabies. Later the rabies progresses to acute pain, hydrophobia (fear of water), violent movements, depression and uncontrolled excitement. The victim in the end stages will experience mania and lethargy which often leads to a coma. The patient will eventually die of insufficient respiration.
What can you do for your puppy that has the flu?
It's rare for dogs to get sick like humans do, and when they are sick there is ussually a definant cause. For example if your dog eats chocalate. In this case your dog needs to be seen by a vet for a shot that will calm the stomach and take away the poison. Also dogs can get Parvo which will begin as a flu like symtom. It is best to take your dog to the vet if they have been sick for longer than 24 hours or appear to be violantly ill (in this case get them to the vet as soon as possible.)
Can aquatic mammals get rabies?
Short answer: yes, but it is highly unlikely.
Long answer:
According to my infectious diseases study materials, rabies can affect ANY mammal.
Now, when I read that I thought just like you: really? even, say, a whale? wow!
So then I was on my way to google to find out, and what I found is that technically, it IS possible, but as the most common rabies carriers (dogs, foxes, coyotes, cats, raccoons, bats...) are landlubbers it is highly unlikely. However, there has been one reported case of a rabid seal (probably bit by a coyote on the beach). Now, say that the seal was to bite a whale, the whale would get infected. Cool, huh? Only, I don't see seals biting whales as a very common thing, but yeah, definitely possible.
What is the most common cold caused by?
A virus causes the common cold. There is no cure or prevention from the cold. The bad part of the cold is the body fighting the cold. When these happen that is what makes you feel so bad. You want to handle the symptoms when they get out of control.
To lessen your chance of catching the cold, wash your hands frequently, avoid contact with those that are carrying the cold virus and keep yourself healthy so the symptoms do not get out of control.
Is a virus considered to be a living or a non-living entity?
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
Viruses are not on the borderline of living and nonliving. There are things that are alive like a bug and things that are not alive like a rock. Nothing is in between.
Hope this helps:)Before the virus finds a host (viruses are parasitic), they are considered "dead" because they have no living organelles and are not active. However, when they find a host and infects it, they become "alive" and starts using them like a host. Hence, they are considered at the borderline and are neither a living thing or a non living thing.
