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.

Why do your hips and leg ache when you get a cold?

Body and muscle aches are common symptoms of colds and flu. However, if it is always your hips and legs that ache (typically the aches from these viruses are more generally located and vary in each episode of infection) it should be discussed with your health care professional to determine if the viruses are causing it or if something else is at play.

Why is your cold not going away when you've had it for two years?

It is not possible for a cold to linger that long. There are other things that can mimic many of the symptoms of a cold, you should have consulted a doctor long before now to get a proper diagnosis and the correct treatment.

If taking antibiotics why shouldn't you get a flu vaccine?

Actually you can take the vaccination if you are taking antibiotics unless you have a fever at the time. Fever is a sign that the infection, for which you were prescribed the antibiotics, is still being fought by your immune system. It is best not to overburden your immune system with vaccinations if it is actively fighting something else.

However, as soon as you are fever-free you can and should get the vaccination. The drug manufacturers indicate in the package inserts that there are no known drug interaction problems with the flu vaccines. Antibiotics would have no effect on the flu vaccine. See the related links section below for a link to more related information at the US Flu.gov site.

What heals a chesty cough?

A hot bath, but allow the room to steam up to clense your throat and to loosen the mucus, also alot of hot fluids work (not cold, it doesn't work espiciallu well) and lots of it! Soup etc etc. Gargle with mint or warm salt water, vicks or sinex work to clear the nose if that's an issue, cough medicine, boiled/throat sweets to numb the throat. Don't talk unless it's vital, rest in bed or on the sofa and let it work :)

Are flu shots everywhere?

The influenza vaccines are available widely and are being offered at numerous locations of pharmacies and health care professional offices for the 2011-2012 flu season in the Northern Hemisphere, which is just beginning this month (October). Get the vaccination as soon as possible to avoid risk of catching the flu before you can get the vaccine.

The H1N1/09 pandemic swine flu vaccine is included this year again in the annual seasonal flu vaccine. The vaccines are now available in formulations for administration by the usual IM shot/jab, the nasal mist, and now, new this year there is an intradermal (ID) vaccine called Fluzone that is injected using a micro-injection system with a tiny needle under the layers of the skin. If you have a preference as to the type of administration route, you may need to call ahead to find out if the type you prefer is available and if you are a candidate for the type you are considering. You can also discuss this with your pharmacist or primary health care professional. It is approved for use in adults age 18 - 64.

The nasal mist is a live attenuated vaccine and can only be used for non-pregnant healthy individuals ages 2 - 49. It is not indicated for those who are immuno-suppressed. The intradermal and intramuscular (IM) injections are made from inactivated ("dead") virus particles, approved for all ages down to 6 months. Infants under 6 months can not be vaccinated due to their immature immune systems.

Is there a plant that can cure the cold?

No, there are no cures for the common cold. There are medications and treatments that can help lessen the severity of the symptoms but this is not a "cure".

Why can't a vaccine be developed straight away when you have the Swine Flu?

It takes time to isolate the virus causing the disease and then to capture it and make it reproduce rapidly in a laboratory to enable the development of a vaccine.

Some strains that are captured and tried may not "grow" well and then a different strain needs to be found to use instead. The medium to carry the viral particles to enable inoculation of flu vaccines does not need to be redeveloped for every type of virus grown, and the testing of the medium does not have to be redone for each annual vaccine that is developed. So, in that aspect of drug manufacturing and testing, the new flu vaccines can be developed much more rapidly than other types of medicines and brought to market faster since the testing of the medium doesn't need to be redone each time.

It was actually astonishing how fast the new vaccine for the pandemic swine flu made it to the end user patient, actually. They were very lucky to find the right strain that would grow easily and reproduce especially quickly to enable the vaccine to get to market even sooner than originally anticipated and in time for the 2009-2010 flu season after the start of the pandemic.

When should you take a 19 month old to the er when they have the flu?

The biggest concern here is the fever, you do not want that getting to high as it could cause serious issues. I would say nothing above 101 considering the young age of the child.

My official recommendation is to take very young ones to the doctor ASAP as the flu in infants can be extremely dangerous and in some cases fatal.

Why does one get the flu shot in October when the flu season begins in December?

You need the vaccination prior to the beginning of the flu season so your body has had time to develop the immunity from the vaccine before the viruses start to circulate in your area. Children take longer to develop the immunity than adults.

It is best to get vaccinated as soon as the vaccine is available to you, which is usually September in the US and March in the Southern Hemisphere. You can't take it too early to work (since the immunity lasts a lifetime to those specific viruses in the vaccine).

In the Northern Hemisphere, the flu season is considered to be from October through March, although some extend that to say through May, especially in the colder regions. So the best time to get the vaccine, if you are an adult, is approximately 3 weeks prior to October which allows your body time to fully develop the immunity after the vaccination before the season starts.

In the Southern Hemisphere, the flu season is considered to be from April through September. Adults would want to have received the vaccinations there approximately 3 weeks prior to April.

Children under 10 and infants 6 months old and over require a series of two vaccinations one month apart and it takes them approximately one month after the second vaccination to achieve the immunity, since their immune systems are immature. Babies under 6 months old can not be vaccinated.

What is epidemic keratoconjunctivitis?

According to http://www.drhull.com/EncyMaster/P/pink_eye.html the answer is as follows: This form of conjunctivitis is the fabled "pink eye" everyone fears, and for some good reason. It is caused by adenovirus type 8. It is transmitted by direct contact from person to person and is highly contagious. Initially, there is a sensation of a something beneath the eyelids with a lot of itching and burning. Soon the patient complains that light bothers his eyes. The preauricular lymph node (just in front of the ear) becomes palpably enlarged - about the only time this node is ever evident. There may be some blurring of vision, which can be (rarely) permanent (less common in children than in adults). Children may have associated upper respiratory infection with a sore, red throat that is negative for strep. This is called pharyngoconjunctival fever. No specific treatment is available. Emphasis must be placed on prevention of spread of the disease, so your child may be quarantined from school for up to a week or two until the symptoms subside. Strict handwashing at home is the best prevention.

Can you get the flu from a person who has allergies?

If the person who has allergies also has the flu, then yes.

You cannot get the flu from someone just because they have allergies, if that's what you're asking.
