Could all these staph Infections be a Terrorist Attact using a Virus?


I mean how hard would it be to put that Virus in clothes and other goods that are being sent over to this Country. I don't know it just seems like in the past couple years that Staph Infection have taken over and that's scary. Where is this coming from? I mean I wonder if our Government, which I am sure they have asked this question to, wonder what is going on? What do you think? Thanks.

I think it is less of a conspiracy theory, more of a scientific explanation...

Like many healthy people, you probably have some Staphylococcus aureus bacteria — usually simply called staph — on your skin or in your nose or throat. Most of the time, the bacteria cause no problems or relatively minor skin infections. But staph infections can turn deadly if the bacteria burrow deeper into your body, invading your bloodstream, urinary tract, lungs and heart.

In the past, most lethal staph infections occurred in people who were hospitalized or had a chronic illness or weakened immune system. Now, a growing number of otherwise healthy people, many of whom have never been in a hospital, also are developing life-threatening staph infections.

A greater problem is that many staph infections no longer respond to common antibiotics. Though most staph infections can still be successfully treated, it may only be a matter of time before the bacteria become resistant to all currently available medications.  (+ info)

Influenza. A respiratory virus. How does that affect your stomach?


I don't understand how people throw up with the flu. If it's a respiratory virus, how does that affect your stomach?

Maybe those people just have a tummy bug.
----------

By resp. virus, they mean it is spread by resp. secretions, not that it only affects the resp. tract. Influenza enters the body through the resp. system, then affects other systems. It is spread mainly by coughing, sneezing, or people touching items that others handle after they cough/sneeze into their hands.  (+ info)

Does the Epstein Barr Virus Affect The Respiratory?


Can the Epstein Barr Virus affect The Respiratory? I've had it for 2 months now, it really sucks.
----------

What diseases does the virus cause?

The Epstein-Barr virus is thought to be responsible for a number of diseases in addition to glandular fever (otherwise known as infectious mononucleosis) and Burkitt’s lymphoma. One of these is nasopharyngeal carcinoma: this is a tumour of the nasal passages and throat which affects up to 2 per cent of people in southern China and also occurs in Southeast Asia, northern Africa and among Arctic peoples. It has been proposed as a possible cause of Hodgkin’s disease (a type of cancer affecting cells of lymph nodes).

Diseases caused by the virus are particularly common among people with reduced immunity. For example, the virus is associated with ‘post-transplant lymphoproliferative disease’, a tumour often found in organ transplant patients. The immune systems of such patients are usually suppressed artificially by drug therapy to help prevent the body from rejecting the new organ.

AIDS sufferers, who also have reduced immunity, commonly suffer from ‘oral hairy leukoplakia’, a condition involving considerable replication of the Epstein-Barr virus in cells along the edge of the tongue. And researchers have suggested that the high incidence of malaria in countries where Burkitt’s lymphoma is prevalent may also play a role in the disease by suppressing the body’s immune system.

Scientists don’t know why the virus causes a relatively mild disease like glandular fever in some people and malignant tumours in others. Some evidence suggests that genetic factors may play a role.

How is the virus spread?

People infected with the Epstein-Barr virus will retain it for life, but it may not make them sick. In fact, the virus infects almost everyone in developing countries and more than 80 per cent of people in developed countries. It is spread mainly via the transfer of saliva between individuals, which is the reason that glandular fever has been dubbed the ‘kissing disease’.

Most people are infected with the virus during childhood, probably by their mothers, and are usually not noticeably affected. On the other hand, people infected for the first time during or after adolescence (10–20 per cent of people living in developed countries) have a 50 per cent chance of contracting glandular fever.

How does the virus work?

The Epstein-Barr virus appears capable of infecting only two major cell types: the outer (epithelial) cells of the salivary gland, and white blood cells known as B lymphocytes (B-cells). Infection with the Epstein-Barr virus develops first in the salivary gland. Large amounts of the virus are released in the saliva, enabling it to spread from one person to another.

Infection of B-cells with the virus causes them to proliferate. This proliferation is controlled by the immune system; if the correct immune response does not develop, individuals are at risk of developing a form of cancer.

The response of the body’s immune system

The Epstein-Barr virus produces about 100 different antigens (large protein molecules) during the active phase of the viral cycle. In contrast, only about 10 antigens are produced during the inactive phase: these include the Epstein-Barr virus nuclear antigens (EBNAs 1–6), and the latent membrane proteins (LMPs 1–3).

The heroes in the battle against the Epstein-Barr virus are white blood cells known as cytotoxic T lymphocytes (T-cells) (Box 1: Acquired immunity: Antibodies and T lymphocytes). These cells combine with certain antigens produced by the virus and kill cells that harbour it. Unfortunately, when the virus is associated with Burkitt’s lymphoma and nasopharyngeal carcinoma it appears to produce only one antigen – EBNA1. T-cells are unable to combine with this particular antigen and will not attack the infected cell. In such circumstances, the virus is able to ‘hide’ from the body’s immune system.

The search for a vaccine

As with most viruses, the best chance of defence against Epstein-Barr is vaccination. Yet a vaccine has been elusive, partly because the virus is so good at hiding.

To prevent Burkitt’s lymphoma or nasopharyngeal carcinoma, a vaccine would need to provide 100 per cent immunity or be capable of establishing a T-cell population that recognises EBNA1. Both tasks are extremely difficult. It may be possible, though, to produce a vaccine against glandular fever and post-transplant lymphoproliferative disease, since both produce antigens that are recognised by T-cells.

For several years, Australian scientists have been engaged on a project to produce such a vaccine. Based at the Queensland Institute of Medical Research within the Cooperative Research Centre for Vaccine Technology, they are conducting a trial with a prototype vaccine using human volunteers (Box 2: The future of vaccines).

One of the first steps in the development of the vaccine was to define the antigens of the virus that are important in the immune control of it. Antigens stimulate the manufacture of  (+ info)

Why do people who are treated with antibiotics for virus infections seem to get well sooner?


Doctors say that antibiotics can not help people who have viral infections. But I have noticed that people with these infections, children and adults get instantly better (within 24 hours) when given antibiotics. I realize that these people could have both bacterial and viral infections. But if so, the antibiotics knock out the bacteria leaving the viruses to continue to do their thing against the body. I also realize that viruses don't care what they attack, they attack both bacteria and humans! So, ... what's going on?

What are the various causes of upper respiratory infections, and what can be done about them?


Should you go high-tech (drugs, doctors, etc.), or stick with chicken soup, 7-Up, and orange juice? What about Vitamin C, zinc, echinacea, and other herbal remedies? Are they scientifically proven to actually help?
----------

Most URIs are viral so antibiotics will not help. Viral URIs usually go away on their own with some rest, lots of fluids, tylenol for pain or fever. If you have a cough with green or yellow sputum and high fever then you should go to a doctor as it may be a bacterial infection in which case antibiotics are indicated.
I don't know of any studies as to the efficacy of herbal remedies although they probably can't do much harm as long as you don't go overboard with them.  (+ info)

Can the common cold or Upper respiratory infections involve vomiting?


My toddler is very sick - she has had a cold and runny nose and coughing, then today out of nowhere she has a fever and threw up her lunch. She fell asleep after she threw up and is sipping on pedialyite. But I can still hear phlegm in her throat and a runny nose that she's had for the past week. Also what kinds of foods should I try to feed her? And how soon should I reintroduce solid foods?
----------

I would get him tested for strep throat, if not treated it can turn into Rheumatic fever, scarlet fever... throwing up and diarrhea, runny nose, watery and itchy eyes, are all symptoms of strep throat. If he developes a rash he's got scarlet fever.

Foods: stick to clear liquids, if she can keep that down move to crackers, if she can keep that down try apple sauce. Mild Mild foods :)  (+ info)

people infected with HIV the virus that causes the disease aids can become unable to fight off infections by organism that normally do not harm people why is it so?
anyone know??
----------

Because HIV and Aids attack the immune system. So basically there will be no barrier between the body and any germs or bacteria.  (+ info)

Some people with a deficit of IgA exhibit recurrent respiratory tract infections. Explain this observation.?


I know that IgA is also called secretory IgA, it is found in mucus and other secretions, and it plays major role in preventing pathogens from getting into the body. But I still cannot understand how is it related to recurrent respiratory infections.... HELP please!
----------

Streptococcus pneumoniae and Haemophilus influenzae are important bacteria in recurrent respiratory infections. The immunological response against them is based on the synthesis of specific immunoglobulins, the generation of complement factors, and phagocytosis.

The role and relative frequency of the above-mentioned in increased susceptibility to respiratory infections is poorly understood. Neither is it known whether the combined presence of several (partial) immune defects contributes to increased susceptibility to infection.   (+ info)

Why do doctors prescribe steroids for respiratory infections?


Why won't Y!A allow open debate without it being considered chatting, btw I like your answer.
