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.

Can you get the flu from being in the cold?
Yes, it is possible but infrequent in otherwise healthy people. Usually the body is infected with only one virus at a time. But, unless you are immune to that particular virus, it is possible to become infected at any time, regardless of whether you are already sick.
The immune system produces various antibodies, so if you are sick with a cold your immune system has already started producing more antibodies, some of which indiscriminately attack all foreign invaders. This is probably why, once you are sick with a cold, you are less likely to get the flu or anything else at the same time since the immune system has already been alerted and is working hard. However, it is not impossible, it has happened. You will know if you get both. Cold symptoms will pale in comparison to the flu and the flu will come on abruptly. What felt like just congestion and a runny nose will turn into a pounding headache, cold sweats, muscle aches and possible nausea. Moreover, the flu symptoms will probably end before the cold does.
The influenza viruses, like swine flu (H1N1/09), reproduce in a method called the lytic cycle.
As a quick and over-simplified explanation of the lytic cycle: the virus attaches to your cell (flu viruses attach to the cells of mucous tissue, mostly first in the nose, mouth and eyes), inserts its DNA/RNA into the cell and that instructs the cell to stop what it was doing as its normal function for the body and start making replications of the virus instead. In that way, the virus, a non-living organism, hijacks our bodies to supply the raw materials and do the work required to reproduce itself. Once that one cell makes a full batch of virus particles, the cell splits open and the "newbie" virus particles go attach to other cells and repeat the cycle entering cell after cell after cell. The hijacking and death of the split open cells help trigger our bodies to begin the attack on the virus. It is then that we will feel the symptoms of both the loss of the cells from their regular duties, and the immune response that includes the fever, excess mucus production, etc.
See the related questions below for more detailed information about the lytic cycle.
The flu is caused by a virus that you must be exposed to in order to get the flu. it's all lies
How long does hiv virus life inside the body?
For one thing, hiv or aids does not kill any body. It's the O I s one gets, otherwise known as opportunistic infections. A cold, pneumonia, cancer, etc. There is many things. Some one with hiv or aids doesn't have enough of an immune system to fight off such simple or common colds or infections that a healthy person takes for granted that his or her system will take care of. I've been hiv now for 25 years and feel fine and work every day. As long as one takes the medication they will probably die of old age or some freak accident. Hiv is in the same category as diabetes, a treatable disease. They have just also announced that they may have a possible cure for it using stem cells I believe, although its many years away before its perfected. It was in the newspapers a few months ago. They have tried it on a person and its showing promising results but it needs further research. Also what should have mentioned before that one has to go from hiv to aids status before they can have comprises from O I s. I am actually in the aids status and have been for over five years now. The only thing that I can really tell you to do to find more answers to some of the things I mentioned is to do your own research on it. If you would like to discuss more of this I will be glad to talk to you or any one else. You can email me at billegram@gmail.com I hope this answered your question.
Does the flu always come with a fever?
The answer would have to be "almost always", if there is no fever or a low grade fever, the ill person will likely be immuno-compromised (have a disorder of the immune system) or they have a common cold virus instead of a flu virus. Symptoms can often be the same, except flu almost always involves high fever and a cold does not usually cause fevers over 101F.
Are viruses non cellular organisms?
Viruses are non-living just like a rock is. Since they are not cells, they can not be alive. However, they can "hijack" a living cell. They have either DNA or RNA which allows this hijacking to occur. By doing this, they can make the host cell make more viruses just like them. This causes the virus to spread.
Can the same virus infect someone twice?
No. The patient's immune system will have made antibodies in response to the first infection (to cure the patient) and these will prevent subsequent infections by the SAME virus. This is the whole basis of vaccinations.
How are the lysogenic is cycles different?
During the lysogenic cycle, the cell is not killed. This is from Apex Btw.
What is the first event that occurs when a viruse a virus infects a host cell?
the virus attaches to the host cells membrane
What are the 2 main components of a virus?
All viruses have 2 basic parts: a protein coat that protects the virus and an inner core made of genetic material.
The Coronavirus cases are 6.8M. I can say the exact number but it always changes the number.
Directly from the CDC website:Small rodents (e.g., squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, and mice) and lagomorphs (including rabbits and hares) are almost never found to be infected with rabies and have not been known to transmit rabies to humans.
Can a computer catch an human virus?
One is a real microbe (human virus). It is a real virus germ, that causes infections in people like the flu and a cold. Computer viruses are not real germs and are only nicknamed a "virus" because they spread like one from computer to computer.
Computer viruses are just software/programs that can be put on and hidden in your computers by other computers through malicious programs that a criminal geek has created to harm your system and make it harm other systems in return. It has nothing to do with germs or real infections.
The coronaviruses are a family of viruses whose symptoms can range from the common cold to something more serious and potentially lethal. A novel coronavirus is currently spreading across the planet, affecting the daily lives of many.
In January 2020, an outbreak of a new coronavirus (SARS-CoV-2) occurred in Wuhan, China. It causes a disease called COVID-19, whose symptoms include fever, cough, and shortness of breath. It can lead to death, particularly for the elderly and people with serious chronic medical conditions. There are currently no vaccines or antiviral treatments available.
More than 150 countries and territories, including the United States, have confirmed cases of the infection since the initial outbreak, and on March 11, the World Health Organization declared it a pandemic.
For more information on this ever-developing situation, consult the Centers for Disease Control and Prevention’s page dedicated to COVID-19, found here.
Is a cold virus an active virus or a hidden virus?
Active. It will go directly to find a host cell and begin the steps of the lytic cycle to cause the host's cell to replicate the virus (see the related questions for more about the lytic cycle). It does not stay "dormant" inside you to manifest symptoms later. An infection will produce symptoms right away if you are infected. Then, once new viruses are made in the host cell, they will burst out and infect more cells and potentially more people.
How can you see a bacterial virus?
there is no such thing as a bacterial virus.
You have a bacterial infection,
or a viral infection
they are two different types of organisms.

EDIT:
you could see micro-organisms using a microscope
Caused by the bacterium Versinia pestis, in short, it can be described as a painful swelling of the lymph nodes develop, which are called buboes, often it is evident in the groin and armpits. Usually there is blackening of the skin due to the accumulation of dried blood under the skin's surface.
Are you contagious when you get the flu shot?
No. Live vaccines are produced with careful culturing methods that ensure the virus is no longer able to do much, if any, harm.
In addition, they're given in the arm, which is not where a virus spreads from, and is not the optimal location for the viruses, so your immune system can quickly get it.
What one of the 7 life processes can viruses do?
VIruses can only reproduce. They can not respire, excrete, nutrition, grow, they don't have sensetivity either. Remember: viruses still are living things because they have genes in them.:) hope it helped. thanks! :P
Does drinking hydrogen peroxide help with herpes?
Sorry hun nothing can kill herpes, antiviral medciation or Lysine is the best treatment for it.
Can the flu cause nose bleeds?
Yes, it actually does. Ive been anemic for years and always get both nose bleeds and headaches
What is the size of the Influenza A virus subtype H2N2?
80 - 120 nanometers (.08 - .12 microns). This is why masks don't help anyone but everyone else. Masks didn't help agains the SARS virus which is 100 nano meters, meaning it's safe to say, it won't help against the swine flu either.
What is another name for Ebola Virus?
The common name for Ebola is Hemorrhagic Fever because you tend to bleed out of every internal and external orifice. Really nasty stuff...especially bleeding eyeballs. Ebola is one of many Hemorrhagic fever...
Common Name: Hemorrhagic Fever
Scientific Name: Ebola
