The virus tries to match the recognition glycoprotein on the outside of the cell it is trying to invade, for docking purposes, or for entry purposes. Generally the membrane that covers this type of virus was taken from a cell it lysed on exit.

Symptoms start two days to three weeks after contracting the virus, with a fever, sore throat, muscle pain, and headaches. Typically nausea, vomiting, and diarrhea follow, along with decreased functioning of the liver and kidneys.
Around this time, affected people begin to bleed both within the body and externally. Prolonged cases are often complicated by the occurrence of long-term problems, such as inflammation of the testicles, joint pains, muscle pains, skin peeling, or hair loss. Eye symptoms, such as light sensitivity, excess tearing, iritis, iridocyclitis, choroiditis, and blindness have also been described.

Some viruses are very specific to certain cells. The cell has proteins on it's surface and a virus will use it a docking station to be able to enter the cell. Some cells don't have that protein and the virus can not enter the cell.

== == Rabies is a deadly disease that works very very fast and pretty much kills all those it infects. There is no cure.

If you or somebody you know has been bitten or even scratched by a wild animal, it is very important to visit the doctor immediately. Try to remember the animal's looks and location so you can describe it to the authorities.

If you have been bitten by a domestic animal you are not 100% familiar with - a neighbor's dog, for instance - find out the dog's shots history and see a doctor and make sure you get a tetnis shot.

The answer to whether HIV gram-stain positive or negative is that HIV gram-stain is negative. They retain the light red or pink color after the stain.

In the 106 to 110 countries that it is found in, perhaps 5%.

Stress in the host cell

A virus feeds off its host cell, and a parasite is an organism that feeds off another organism.. hmmm sounds like to me they are similar. like the words "chips" and "french fries" :-)

Saying a virus "feeds" off its host cell is inaccurate. It injects its own DNA into a host cell, thereby destroying the host cell and creating more viruses. There really is no similarity between viruses and parasites.

There is no single shot of rabies vaccination. Three shots of preventive vaccination are given on day 0, 7, 28. Alternately on day 0,28 and after six months. But I will advice to go for five does of anti-rabies vaccine, even if you are protected. The sixth shot may not be taken. But you will take it out of immense fear generated by people around you. Your physician will be forced to give you that shot. You can go for it.

The facts and fiction re: alcohol based hand sanitizers. Unless the manufacturer is providing an independent lab test re: the two most common strains of norovirus (feline and murene), you should remain skeptical i.e. the kill claims. Murene strain is extraordinarily difficult to conduct tests for, and very very few manufacturers of hand sanitizers have been able to demonstrate that 62% alcohol could possibly be effective against Norovirus. Alcohol does not penetrate dirty hands. Alcohol evaporates in high temperatures. Alcohol breaks up when stored in high temperatures (which would suggest that it is rendered ineffective). There is a new product on the market, alcohol-free that comes with third party test results i.e. both strains of norovirus. Its very expensive--3x-4x any other hand sanitizer--but the financial cost of a norovirus outbreak on a cruise ship or a hotel is hundreds of thousands of dollars per day. Will hand sanitizers actually prevent a norovirus outbreak? That remains to be seen. Can hand sanitizers mitigate the spread of norovirus? Yes.

No. Influenza viruses are active. You are infected, so your body creates antibodies that disable the viruses in 7 to 10 days. Then your body eventually removes all of the "dead" ones from your body. Latent viruses, like HIV, hepatitis C, and Herpes viruses, infect you but don't cause evidence of disease until later, sometimes years later, as they lie dormant (latent) hidden in your tissues until the disease they cause eventually manifests.

Quite simple actually. A protein capsid and genetic material within the capsid and sometimes digestive enzymes to destroy bacterial DNA, for instance ( DNA, T even phages, for instance ). Retroviruses have RNA as their genetic material, so they need reverse transcriptase enzymes to replicate cell DNA from their RNA template. They also can have membranous coat, usually take from a cell they are exiting.

There is no way to answer this unless you tell what the name of the disease is in your question.

The baby would be more likely to get it from you, especially if they are under six months old, since they can not take vaccines for influenza until after that age. But the answer is yes, they can get the flu as babies and if they have it, they can give it to others. In fact, since their immune systems are immature, they may be able to spread the virus to others for a period longer than older children and adults can. They are also more susceptible to severe complications of influenza with immature immune systems and lungs. It is recommended that anyone caring for babies under the age of six months get vaccinations so they can not get and spread the virus to the baby and check with your pediatrician about when it is safe to take the baby out into the community.

No. This treatment for the flu contains no ingredients that can give you the flu or any other infectious disease.

There are actually 8 kinds of Herpes viruses:

HHV1: Causes Oral Herpes blisters.

HHV2: Causes Genital Herpes blisters.

HHV3: Called Herpes Zoster. Is the virus that causes Chickenpox and also Shingles later on.

HHV4: Also known as the Epstein-Barr virus. It causes Mononucleosis.

HHV5: Also known as Cytomegolovirus. It also causes Mononucleosis.

HHV6: Causes Roseola.

HHV7: Closely related to #6 and also causes Roseola.

HHV8: Recently discovered in tumors Kaposis Sarcoma ususlly found in people who have AIDS. It can cause other types of cancers in immunosuppressed people.

A spider is an araneae, an order of arachnid. rabies can only afflict warm blooded creatures like mammals.

If you mean your pets, you can get vaccinations to prevent it. If you mean avoiding getting it yourself, all I can tell you is to not let an animal with rabies bite or scratch you so the saliva doesn't get into your blood system.

There are three different types of viruses. The first one is Macro Viruses. Macro Viruses use to infect and spread to other files viewed by that software. For example Word and Excel have macros and macro viruses can spread by exploiting these commands. The second type of virus is called Worms. Worms duplicate themselves and use communications such as email to spread. They can look at your email address book and send themselves to users in your address book. The third type of a virus is called Trojan. Trojan Horses are programs that say they perform a particular function but in fact do something different, for real they could infect your computer with a virus or erase your files. Viruses can be stopped by activating an anti-virus program, this allows you to scan all of the files programs and everything else on your computer for viruses, and if it finds some then they will be deleted.

Helical capsids are usually formed from one protein that interlocks to form a helix-like structure around the viral genome. They are usually more common among viruses that infect plants, though influenza, measles, mumps and rabies viruses all have helical capsids. They are 120 to 270 nm in diameter.

A lytic virus will destroy its' host cell at the end of the lytic cycle.

Flu is caused by a pathogen (by viruses) but is not the pathogen itself, flu is the disease the pathogen causes. Flu is short for influenza which is an infectious disease of the respiratory system caused by influenza viruses.

A retrovirus transcribes RNA into DNA, whereas a regular virus transcribes DNA into RNA. (:

Rabies cannot be cured. It may only be prevented via vaccinations. If a human is bitten by a suspected rabies animal, the vaccination must be administered within 2 hours of the bite so as to produce inhibitory antibodies against the rabies virus. But once a person is infected with rabies, they will be dead within 2 weeks. Rabies has a 100% death rate in non-vaccinated individuals unfortunately...
