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.

What sickness feels like a flu?

Many viruses cause similar symptoms to those of the flu, and the complex of general symptoms of the flu can also be common in other infectious diseases or other non-infectious conditions. Many viral infections and flu-like illnesses cause similar symptoms to those caused by influenza viruses. These are often present in viral gastroenteritis ("stomach flu"), and the common cold, for example.

Sometimes these symptoms can come from other and non-infectious conditions, such as early pregnancy, allergies, toxic chemical exposure, etc. The symptoms might include: headache, nausea, malaise, fatigue, cough, body aches, fever, and dizziness, to name only a few of the more common symptoms that are referred to as flu-like. See the related questions below for more complete lists of cold and flu symptoms.

What does green mucus from cough mean?

It means that you have a bacterial illness or virus. Your body should clear it out, but if it doesn't, it may go into your throat and chest. You know that has happened if you have a hard time breathing or you have thick-sounding coughs. If this happens, Mucinex will help cure it up quickly. Drink huge amounts of water to speed the process!!

Is hey fever contagious?

A fever by itself is not contagious. Fever is a generic symptom and sign that only says the body is fighting something. It is what is causing the fever that MAY be contagious.

Contagious WITH fever as well:

  1. Measles, Mumps, Rubella (MMR vaccine has been controlling these)
  2. Strep, and Meningitis
  3. Flu, Bronchitis, Upper Respiratory Infection, viral or bacterial
  4. The Plague
  5. Ebola virus

As just ONE example of a non-contagious problem that can produce fever:

  1. inflammation in the body, from ANY cause, such as cancer, which is never contagious

Why do people get flu?

In climates that experience winter, the influenza virus tends to survive longer and transmit itself better in cold and dry conditions, which leads to more people contracting the flu during those colder months. In climates that do not have a winter season, however, the flu is more common in periods of high humidity and lots of rain. Scientists aren’t sure why that is, but it doesn’t seem to have to do with the immune system being weaker in the winter, contrary to some beliefs.

How long does the seasonal flu last?

if you have a helthy body then a few days for example 3

if your body is poor it lasts for around a week

How is the A H1N1 09 vaccine made?

H1N1 is the general name of several influenza viruses, of which H1N1/09, the pandemic swine flu, is one. It is a Type A influenza virus and the H and N stand for the two proteins on the outer surface of the virus. See the related question below with more information about the make up of H1N1.

How long does avian influenza last?

It is estimated that 50 to 60 % of those who have the Avian Flu do not survive. For some, the illness takes them quickly with overwhelming fluids filling in the lungs, others may need long term intervention and ventilator support, and even induced coma, to just survive.

Is runny nose a symptom of getting throat infection?

A runny nose can be a sign of many things, some a sickness, some not a sickness.

Sicknesses could include flu, nasal/sinus infection or a cold.

Non-sicknesses could include allergic reaction, hayfever and not blowing your nose enough.

How can the flu be cured?

The flu, like a cold, is a virus, and so far, we really don't have a reliable way to treat viruses. That's why the cold, flu, herpes, HIV, etc aren't cured. the body develops its own response as best it can (cold, flu) until we heal, or we keep the virus forever (herpes, HIV).

How does the flu differ from the common cold?

They are both viruses but the flu is typically more intense. The symptoms are similar but more severe with the flu.

Which enzyme in tears kills germs?

Your tears contain the enzyme lysozyme. This enzyme acts by disrupting the cell-walls of gram-positive bacteria by digesting the peptidoglycan in them, thereby preventing infection.

This enzyme is also found in your saliva and is an example of a non-specific immune response.

How many people does the flu kill?

Asian Flu reached an epidemic in 1957, crossing the ocean and reaching the US. About 69,000 people died in the US that year from Asian Flu. For more iformation see the link to the Wikipedia page for this topic (under Related Links).

How do you relieve a stuffy nose without using medicine?

Take some allergy medicine and get lots of kleenex. (the blow and wipe your nose) :D

How does the flu shot work?

The vaccine in the flu shot contains either a "dead" (inactive) or a weakened form of the expected invading virus (or viruses) which can not make an otherwise healthy person sick. Our bodies use these antigens (vaccine's virus particles) as a template to create the right antibodies, that will have the right pattern to match and know how to destroy those same viruses in the wild (normal strength), if they enter the body in the future to try to use our cells to replicate themselves. Our bodies remember each virus pattern that is in the vaccinations so that they can make those matching cells to protect us again from that same specific flu strain (or sometimes strains that are very similar).

Our bodies also have the ability to determine when a virus has invaded and, if there is a match to that strain of virus stored from a prior invasion, the immune systems quickly make up a lot of those attack cells, that worked in the past to destroy the invading virus particles. If it is a new invading virus, usually our bodies can make cells that can match just right to destroy the new invader in a week to ten days. (They can sometimes do this even more quickly for bacteria and other microbes).

It is during this time period, when the body is matching and making the attack cells to "kill" the invader, that we feel sick until our body finds the key pattern of cells that will match and destroy that specific virus. The body "remembers" the pattern each time it makes cells that work to kill germs, so any time that same germ comes along again, or even sometimes a similar one, the immune system wastes no time in getting rid of the invading organism, because it knows already what will work. That is why, once we have had a flu virus like H1N1/09 Swine Flu before, we won't get sick from it again. The body will already know what cells to make and will send them out to destroy the invader.

This is also how vaccines help our bodies build up immunity or resistance to viruses and flu. The immune system remembers the pattern of the antibodies it made when it was exposed to the virus particles in the flu shot and if that type of virus turns up in the environment later, the cells are made and attack the virus before it can make us sick.

What vaccines are used for the flu?

The trivalent seasonal flu vaccine protects against the three strains of the flu that are expected to be causing infections in that flu season. The three flu viruses selected usually change each year. The vaccines don't protect against all strains, so it's not a guarantee, but is recommended for all people (except infants under six months, those with allergies, etc.- see list of those who should not get a flu vaccination in the related questions below). It is especially recommended that children, older adults, and people with chronic medical conditions get vaccinated every year before flu season. There is a new vaccine in the 2012-2013 flu season that is quadravalent, i.e., it has protection against four strains of the flu (FluMist Quadravalent).

There are formulations of these vaccines for administration three different ways: The standard IM (intramuscular) flu shot/jab, a new (in 2011) vaccine for ID (intradermal) administration (in the layers of the skin), and the two nasal sprays. The IM and ID shots contain killed virus and are safe for use by most people (see exceptions in related question below).

The nasal spray is made with live, weakened virus, and is, therefore, recommended only for those aged 2-49 years who are not pregnant. The people with suppressed immune systems are also usually advised to use only vaccines made with inactive "dead" viruses.
For the 2012-2013 flu season in the US, this year's trivalent seasonal flu vaccines will protect against the following three strains of influenza:

  • Type A/California/7/2009 (H1N1) ~ the "swine flu vaccine",
  • Type A/Victoria/361/2011 (H3N2), and
  • Type B/Wisconsin/1/2010.
There is also a new vaccine in the 2012-2013 flu season that is FluMist Quadrivalent. This new vaccine includes two Type B strains of flu instead of one. It contains B strains from both the B/Yamagata/16/88 and the B/Victoria/2/87 lineages in addition to the same strains of the Type A viruses (H1N1 and H3N2) that are included in the trivalent vaccines for this season. See the related questions below for more info.

For the 2012-2013 Flu season in the US, the following vaccines for influenza are approved for use:
  • AFLURIA Trivalent made by CSL/Merck

  • AGRIFLU made by Novartis

  • FLUARIX Trivalent made by GlaxoSmithKline Biologicals

  • FLUMIST made by MedImmune Vaccines, Inc.

  • FLUMIST QUADRAVALENT made by MedImmune Vaccines, Inc.

  • FLULAVAL Trivalent made by ID Biomedical Corporation of Quebec
  • FLUVIRIN Trivalent made by Novartis

  • FLUZONE made by Sanofi Pasteur, Inc.

  • FLUZONE - High Dose made by Sanofi Pasteur, Inc.

  • FLUZONE-Intradermal made by Sanofi Pasteur, Inc.

Why are you having a reaction after taking a flu shot?

Many people do get a local reaction to the flu shots. It is the body responding to the presence of the virus that was in the vaccine. This immune response is exactly why you get the vaccination. The body recognizes the invading virus as foreign and sends the attack team to the rescue. The soreness and tender red area should be gone in a few days, if not, then you may need to be sure there is not a local infection from the needle by having it examined by a health care professional.

Usually, even though it seems the wrong thing to do at the time, if you use the muscle where the injection was given, the soreness will go away faster. I ask for my flu shots in my right arm to force myself to use it since I am right handed and now that I've started doing that, I have much less soreness after my flu shots and the soreness lasts a shorter time period.

If you are talking about a reaction that is not localized, as in an allergic reaction with lip, tongue or facial swelling or trouble breathing, then you need to get urgent medical attention since it could be you are allergic to eggs or some other component of the vaccine.

What does the Swine Flu cough sound like?

The swine flu cough is usually very easy to distinguish from other types of coughs.
It will usually sound something like this "oink" "oink" "snort!" "oink"!

How many people died because of Swine Flu in Philippines?

In the Philippines as of July 3rd, 2009 there have been 1,709 confirmed cases of influenza A virus subtype H1N1 (aka swine flu) with one death, a 49 year old woman June 19th, 2009.

Is 102.2 a high fever?

No. 99.2 IS a fever; however it is only considered a very Low Grade fever. Considering that a ' normal ' reading in body temperature is 98.6 , a reading of 99.2 would be considered quite low & not a cause for alarm.

Is there such thing as H5N1?

What are you talking about? You typed the same exact thing? Yes it's the same, it's Bird Flu aka Avian Flu, and technically called H5N1. Your question is confusing, it takes on the same characteristics as the following mock question. Does CONFUSING mean the same thing as confusing? Hope that helped buddy.

Can a flu vaccine be given to a sick patient?

Unless they have a high fever, yes and they probably should have one because they are sick. However, there are a few circumstances when the vaccine should not be given. See the related question below about who should not get a flu vaccination.

Can you catch a cold from being around someone that has a cold?

Colds are spread when germs enter the body through a moist body surface, typically the eyes, nose, and mouth. Some transfer of fluid between an infected person and a healthy person (e.g. a sneeze, a kiss, a shared beverage) can spread a cold. Also, a person with a cold can contaminate a surface such as a doorknob with his hands. If a healthy person touches that contaminated doorknob and then rubs his eyes or nose or eats with his hands, he can get the cold. For this reason, regular and thorough hand washing is recommended especially during cold and flu seasons.
Colds can be spread by one that is sick breathing on another who is not sick. If the other person breathes in the sickness there is a chance that the healthy person will get sick.
Sneezing, coughing, touching your face and mouth and then shaking hands with people.

poor hygiene and spread of infection between humans
Sneezing
colds can spread by when u touch or eat something and someone else comes and touch or eat it tyhen that person has the cold in about a week or less
sneezing, touching or using the same silverware.
they're airborne and also can be caught by touching a foreign object with the germ then touching your face.
You can spread the flu by coming to school sick, if you do not wash your hand after using the toilet you have spread over 2,000 germs on your hands. always wash your hands before you eat. Wash your hands after touching money. If you follow these steps you should stay healthy!

ALWAYS GET YOUR FLU SHOT!
Nasal secretions containing cold viruses contaminate the hands of people with colds as a result of nose blowing, covering sneezes, and touching the nose. Also, cold viruses may contaminate objects and surfaces in the environment of a cold sufferer.
people not washing their hands, not catching their snot in their hands when they sneeze.

other people touch things that people with colds have touched so that is how they spread.
You contract the cold by getting the virus inside your body, simple as that. Mouth, ears, nose, eyes, and cuts are the way that colds are usually contracted. Colds can also be contracted through sexual organs.

The reason getting the cold on your hands is bad is because touching any of those vulnerable entrances will spread the virus there immediately.

Once a person is infection, the virus likes to wait in their throat in and nasal passages when it comes to spreading. While in their throat, the cold will be spread whenever they cough or exhale. While in their nose, it irritates the walls of the nose and cause more mucus to be produced, giving it a nice little environment to live in and exit the body.

Tender armpits the day after getting flu shot in same arm?

The same happened to me! I got mine Oct 2012 and I feel terrible and have a really bad rash...I never get the flu so I never get the shot but I was required for a clinical and now I have bronchitis with bloody sputum, headache, and this terrible rash!!
