Cold and Flu

Questions and answers about the "Common Cold"; symptoms in the upper respiratory tract like sneezing, scratchy throat, and runny nose, but adults don't typically have fevers. Colds are usually caused by the rhinovirus (up to 40% of colds), or Coronaviruses (about 20%), but there are more than 200 viruses that can cause the common cold. Also questions about the seasonal flu, also called "regular flu", caused mostly by Type A and Type B Influenza viruses. Flu starts with similar symptoms as a cold only it hits faster and harder and usually includes fever in adults. Although the "stomach flu" is a common term, it is not a real diagnosis. The proper medical term for stomach flu is gastroenteritis (an intestinal disease, sometimes viral but also bacterial), it is often mistaken for influenza because the flu can sometimes include vomiting and diarrhea.

When can you return to work after having flu-like symptoms and fever?

A person who is sick with the stomach flu is contagious for at least 3 days (and often 2 weeks) after symptoms have stopped. That means there are still stomach flu viruses present in your feces for at least 3 days after you have recovered. Ideally, you should stay home from work for 3 days. If this is not possible, you need to take extreme care not to spread your illness to others. Hand washing is very important. Don't touch anyone or anything without clean hands. If you work as a food service provider (restaurant or cafeteria worker) you MUST WAIT 72 hours before returning to work. Contagious food workers are often responsible for outbreaks of the stomach flu.

The stomach flu is really viral gastroenteritis. It is caused by a variety of different viruses and is unrelated to influenza (the real flu). The main symptoms are vomiting and/or diarrhea. When a person is sick with the stomach flu, the viruses that are causing their illness are present in their vomit and feces. Their vomit and feces contain millions of viruses. The illness is transmitted when a few of these viruses accidentally get into someone else's mouth.

Washing the viruses off your hands and body when you are sick is extremely important to avoid spreading the stomach flu. Particles of vomit can fly around the room when you are vomiting so cleaning sick room surfaces is also very important. The viruses can also live for weeks on surfaces so you must clean. Lysol disinfectant spray kills these viruses as does cleaning with a solution of 10% household bleach in water. Clorox wipes and Lysol wipes DO NOT kill these viruses.

A sick person is contagious (still producing viruses) for at least 3 days (often for 2 weeks) after their symptoms have stopped and they think they are well. Stay away from other people as much as possible while you are contagious. Keep young children home from day care or preschool for 3 days after they have recovered from a vomiting illness to avoid starting an outbreak at your school. If you work as a food service provider (cafeteria restaurant worker), do not return to work for 3 days to avoid starting an outbreak.

Is the influenza virus vaccine the same as pneumococcal vaccine?

No, they are different infectious diseases of the respiratory system. However, they can be associated since bronchitis and pneumonia are common complications of influenza. Influenza is caused only by influenza viruses, but bronchial pneumonia, bronchitis and other respiratory infections can also be caused by other infectious agents such as bacteria and fungi.

Whopping cough can you still be infected?

According to the Center for Disease Control in Atlanta, "Pertussis (whooping cough) is a very contagious disease caused by a type of bacteria called Bordetella pertussis. This is one of the most common vaccine-preventable childhood diseases in the U.S. It's important to remember that both children and adults can get pertussis. Since the 1980s, there's been a dramatic increase in the number of cases of pertussis, especially among teens (10-19 years of age) and babies less than 5 months of age. In 2005, there were more than 25,000 total reported cases.

Could the Spanish flu ever return someday?

yes because it could come more than one time and it's a kind of disease which sometimes return.

The real question is not can the spanish flu return, but when.

What is above is not pessimistic, scientists consider this phenomenon as a normal evolution.

How many people in the Philippines are affected by a H1N1 virus?

That information is no longer being kept or made available. The counts of cases of H1N1/09 is no longer done. Testing is not often done to determine the type of flu and states are no longer required to report separate counts of H1N1 flu infections to the CDC in the US. Most, if not all, countries are no longer keeping counts of cases of H1N1/09, but monitoring of the total incidences of flu during the flu season is still continuing.

Do cough drops have alcohol in them?

-i think just sugar alcohol that is non addictive - its probably better to ask a doctor because the back of my cough drop package(over the counter menthol cough drops) say for under 3 years ask a doctor, so there may be some type of alchohal in it.

What is the symptoms of a runny nose?

Several things could be causing this.

Allergic rhinitis, season allergic rhintis, sinusitis (chronic or acutre depending on how long it has been going on for), perrenial rhinitis or other allergy. Ot could also be a chronic cold.

See your doctor for a diagnosis

Hope this helps

I do not know for sure what you have. It could be a chronic condition but not life threating.

Real meaning of pandemic?

World Health Organization Definition of Pandemic:

"An influenza pandemic occurs with the appearance of a new influenza virus against which none of us has any immunity. This results in several, simultaneous epidemics worldwide with high numbers of cases and deaths. With the increase in global transport and communications, as well as urbanization and overcrowded conditions, epidemics due to the new influenza virus are likely to be established quickly around the world."

How do you get rid of a sore chest?

1) you should see a doctor. But when penicillin based antibiotic drugs stop working, you should take z-pak. It's a new antibiotic that will kill the crap out of anything. 2) if you're looking for home remedies, you should look into trying to boost your whole body's immune system. You can do this by eating: acidophiles (the stuff found in yogurt, but you can get it in a pill), multivitamin, green tea, garlic, Shitake mushrooms ( this stuff really worked for me and you can get it in a powdered form), Fish oil is good for making your immune system not overreact to things which is what kills you in a stroke or heart attack 3) Things you can do that don't have anything to do with eating Make sure you get lots of sleep. Losing sleep is possibly the number one reason (directly or indirectly) that our immune systems get weak. The immune system is in a large way controlled by the brain and losing sleep will play havoc with the hormone balance that the brain uses to regulate your immune system. You should also look into getting a humidifier with some oregano along with some mucinex for in the morning.

Is a viral infection contagious when it is a severe sore throat?

Sore throats may be caused by either bacteria or viruses.

Viruses often give symptoms like runny nose, watery eyes and cough -- but not always. Bacteria (strep) usually are not associated with these "cold" symptoms.

It is impossible to tell just by looking at the throat whether it is a virus or strep throat. You have to swab it. Currently, there are no antibiotics that work well against viruses that typically cause a sore throat. That's okay because the body gets rid of this on its own, so all you have to do is treat the symptoms like the pain.

Strep throat needs antibiotics to cure it. A person with strep throat is considered non-infectious after the first 24 hours of antibiotics. If your child has strep throat she should stay away from others until that 24 hours is up.

Viruses, on the other hand, are most infectious usually before you have symptoms, such as a sore throat so it is not necessary to keep your child home if she only has a viral sore throat. For many reasons I believe it is important not to treat a "strep throat" based upon observation alone. The throat should be swabbed for culture.

What is the purpose for cold medicine?

it doesn't cure the cold, because it's viral. Cold medicine just helps with the symptoms while our bodies get over it time. Drink fluids, good food, and rest will help you you alot when getting over a cold.

Why do some people who receive flu vaccines still get the flu?

Unless you are exposed to the flu before the vaccination is effective, it would not actually be the flu that causes these flu-like symptoms after a vaccination. It is not uncommon for symptoms that are flu-like (mild fever, achy muscles, headache, malaise, etc.) to occur immediately after receipt of a flu vaccination. This is not an indication of a viral infection, but, rather, these symptoms are due to the body's normal immune response to the vaccine and should go away within a couple of days. Since it is the normal body reaction to a vaccination, you would not be contagious to others who are healthy, either.

Vaccines trick the body into thinking there is an infection when there isn't. This causes the immune response that begins the process of creating the antibodies that will be able to inactivate the type of pathogen contained in the vaccine if you should be exposed to the same one in the wild after the vaccination has taken effect. [This takes usually around two weeks time after the inoculation in otherwise healthy people who are adults or children over 10 years old. Children 6 months old up to 10 need a series of vaccinations that take longer before effective. Babies under 6 months old cannot be vaccinated because their immune systems are too immature.] The immune response not only causes antibody production, but also results in the other germ-fighting mechanisms (which can include slight fever and the other flu-like symptoms).

Otherwise healthy people are not able to catch the flu from flu vaccinations because the pathogen in the vaccine is either totally inactivated/"dead" or is severely weakened so that it is not able to cause the infectious disease.

See also the related questions below for more information about the processes of an immune response.

What is the meaning of common cold?

The common cold is a viral illness caused by a variety of viruses. It is not a deadly disease. It usually clears up in 7 to 10 days without treatment. Antibiotics are not effective against the common cold.

Some people take medications to help with the symptoms of the common cold, even though these medications do not make the cold get better faster. The only thing proven to decrease the length of a cold is zinc lozenges, and only in adults.

What are the symptoms in a horse for the flu?

The signs of tetanus (also known as lockjaw) in horses are: The inability to open mouth to eat or drink; Eyes wide open and ears rigid; Stiffness in the entire body; Extremely sensitive to sights, sounds and/or touch; Convulsions and eventually death. Scroll down this page to a link to a website that explains signs, treatment and prevention of tetanus in horses.

How long until you gain your taste back after the flu?

Usually your taste will return after your sinuses have healed from your recent bout with the flu. When in doubt, please seek the help of a qualified physician for appropriate diagnosis and treatment.

What antibiotic is used to treat the flu?

You would not be given any antibiotic for use to treat a cold or flu. They are both viral infections, not bacterial infections. Antibiotics are only for bacterial infections. If you have a secondary bacterial infection with a viral infection, you might be prescribed an antibiotic to treat that secondary infection, but not for the virus itself.

The body is protected against harmful flu viruses by?

when you eat food there is bugz in it and the bugz go into your liver and intestines this is just when you eat bannanas and apples and sometimes chocolate. so dont eat them or you will look like a bug and die

Can you catch swine flu through food at a restaurant?

No because it's a respiratory disease... And if it did mutate and get on the pig... You are suppose to heat them up before eating them...

---- Not if the pork were cooked. Influenza virus is destroyed by heat [167-212°F (75-100°C)].

As always when handling raw meats, using normal precautions with hand washing would be important if there were swine flu virus on the meat. However, even though it is theoretically possible for a person with swine flu to pass it to a pig, it has not yet happened as far as anyone can tell.

Can the flu lead to other illness?

The obvious answer is influenza. The flu virus is what causes you to get the flu.

Complications of the flu can be pneumonia (viral or bacterial) and other secondary respiratory infections such as bronchitis. It can cause sepsis (whole body infection with pathogens in the blood stream-"blood poisoning"). It can cause laryngitis from coughing. It can cause dehydration and associated imbalances of the electrolytes (such as blood sodium levels and potassium levels), constipation and kidney and liver damage from the dehydration. It can cause Reye Syndrome in patients who are 18 and younger if they are taking aspirin therapy (do not give aspirin to anyone in that age group for the flu without specific instructions from their doctor). It can cause Guillian-Barre Syndrome in some people. It can cause exacerbations (increases in symptoms or uncontrolled symptoms) of underlying medical conditions such as diabetes mellitus, Asthma, COPD/emphysema of lungs, CHF and other heart diseases, chronic and acute kidney failure, respiratory system failure, liver failure, hematological conditions (blood disorders), neurological conditions, neuromuscular conditions and other systemic medical conditions.

Can you have bronchitis with little or no cough I started out with a little stuffy nose and slight sore throat with chest congestion But dr said lungs sounded clear so I am confused?

That is exactly what happened to me and i happen to be quite experienced with lung problems. I have just gotten it again. do you have any wheezing or chest dicomfort? If you do, i would think yoiu have bronchitis
