Why are antiretrovirals not efficacious in treating H1N1 influenza?
Because H1N1 influenza viruses are not retroviruses. Therefore, they are treated with antivirals instead of antiretrovirals. They are also from different families of viruses. Influenza viruses, like H1N1, are in the viral family called Orthomyxoviridae. Retroviruses are from the viral family Retroviridae. Retroviruses are very different viruses with different methods of replication and, therefore, require different treatment.
The influenza viruses and retroviruses are alike in that they are considered RNA viruses. Some people mistakenly think that the R in RNA stands for retrovirus - it actually stands for Ribonucleic acid. (DNA is Deoxyribonucleic acid). While retroviruses and H1N1 are both RNA viruses (instead of DNA viruses), retroviruses are able to transcribe that RNA into DNA, which is what instructs the cells they infect in the viral replication process. H1N1 does not convert its RNA into DNA. The term "retro" in retrovirus refers to this reversal that makes DNA out of the RNA.
What percent of people a year get the astrovirus?
2-9%of children will get this new virus. 90% of children by age 12 have the antibodies for it and show that they had it and recovered. The rate for adults is higher.
Do vaccines destroy viruses only?
Vaccines do not destroy pathogens, they give the immune system antibodies so it can destroy a pathogen before it causes an infection. Vaccines do exist for some bacterial infections.
you should first go to the hospital to get it confirmed and if you have been bitten they can treat you by giving you around 30 shots in your stomach
Deformed wing virus is suspected of causing the destruction of hundreds of thousands of honey bee colonies across Europe and North America.
Specifically, the virus is one of 18 known to afflict honey bees (Apis spp). The virus shows up in all parts of a honey bee's anatomy except the legs. It results in severe deformities and swift death (within 48 hours).
Where do virus and bacteria come from?
Viruses and bacteria have been around long before we have been. They evolved in the ocean and seas as did other animals and fish.
Why aren't all viruses as deadly as Marburg and Ebola?
Marburg and Ebola are extremely infectuous, especially in hospital settings which may lack proper prophylactic protocols, where it's so frequently treated (in at least one breakout, Ebola Zaire was passed by nurses who had run out of hypodermic needles, and were re-using the same needle, thus spreading the disease). The symptoms of filoviruses are very similar to other viral antigens that aren't as lethal, so frequenly Ebola is misdiagnosed. And victims of Ebola generally express no immune reaction, thus the disease has free range.
It should be noted, however, that Ebola is very low on the list of worldwide disease realted mortality, way below Typhus and many others,
Is vaginitis viral or non-viral?
It could be either. In most cases, vaginitis is a bacterial disease caused by Gardnerella vaginalis, although some protozoans, such as Trichomonas vaginalis, or yeast, such as Candida albicans, can cause vaginitis. There can also be viral vaginitis, most commonly caused by herpes simplex and transmitted by sexual contact.
How many people die of rabies every year?
There is definite statistic for this but less than 5,000 people a year.
According to the CDC website only one or two people die each year in the USA of rabies. It is usually because they were unaware they were exposed. Most animals in the US that carry rabies are wild. i.e racoons, foxes and bats. Domestic dogs and cats hardly ever have rabies.
Viruses are neither aerobic nor anaerobic.
Are the flu and Swine Flu the same?
No, Swine Flu is just one strain of the many flu viruses. Flu is an abbreviation for influenza. So Swine Flu is a type of flu, but all flu is not the swine flu, there are other kinds.
You had your flu shot when you went to see a doctor for cold and flu Is the flu shot effective?
Yes, flu vaccines will work. It is basically dead or weakened flu viruses that are injected into your body. When your immune system finds the viruses, it makes antibodies to kill them, and this develops an immunity to that specific type of flu.
If you are asking how long from the time you get the shot until your immunity is developed, then for healthy adults it is usually 2-3 weeks after the vaccination. Children under 10 need two vaccinations given a month apart because of their immature immune system functioning. Their full immunity will develop 2-4 weeks after the second vaccination.
Is glass permeable --can certain viruses permeate glass?
sure , no yes the virus size is smaller among the other infectious agents, but sure it is not capable to cross glass
What are the risks when you have a viral infection and you have a flu shot?
Mild and minor infections may not prevent your getting a flu vaccination; however, if you have a fever, then you should postpone until the fever is gone. Tell the clinician before the flu vaccination that you recently had or still have the infection, but that you have no fever (they will ask and determine if there is a reason not to give you the vaccine).
In healthy adults, our bodies can deal with two different viruses at the same time, so your ability to fight the viral infection at the same time as having an immune response to the vaccine should not be an issue if you do not have a fever. If you have a fever or if you have a serious bacterial infection and are still taking antibiotics, then it is best to wait until that is gone, or consult your health care professional for advice about getting a vaccination. It might be determined that you should wait because then your body may have more difficulty working on both problems at once and it could make it take longer to both fight the active infection and to build up the immunity with the vaccine.
Is Swine Flu caused by microorganisms?
Swine flu is caused by a virus. Viruses are submicroscopic organisms that are so small they can only be "seen" with an electron microscope. A regular microscope does not allow us to see things as small as a virus particle. See the related questions below for additional information about the pathogen that causes the H1N1/09 swine flu.
What characteristics do scientists use to group viruses?
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
What is a virus molecule of genetic material surrounded by a protein coat?
The retroviruses are enveloped viruses that have two complete copies of RNA. They also contain the enzyme reverse transcriptase.
How can viruses be treated medically to reduce their numbers and prevent them from spreading?
They can be reduced and eliminated by vaccination. We are working on eliminating rabies if all would have their dogs immunized.
Why are viruses thought to be one of the greatest threats to human dominance of the planet?
Viruses are considered to be a serious threat to humans because they are very difficult to control. Very few things can control viruses except antivirals.
What is the differences between a compound and electron microscope?
The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small.
The electron microscope uses electrons to "see" microbes or viruses.
Can diphtheria be provented like the flu?
A diphtheria vaccine is effective for prevention and available in a number of formulations.
Viruses are not classified that way. They are herpes viruses.
What is the energy source of the flu virus?
The flu virus is a non-living thing, so it doesn't have its own energy source. To reproduce, it hijacks the cells of a living being, such as the upper respiratory cells of a human, and uses the energy of those cells to make more copies of itself.
