Influenza (also called "the flu") is a viral infection in the nose, throat and lungs. About 10 to 20 percent people get the flu each year. Some people get very sick. Tens of thousands die every year in
What are the Symptoms of FLU?
The flu may cause fever, cough, sore throat, a runny or a stuffy nose, headache, muscle aches and tiredness. Some people describe the flu as the worst cold of their life. If you get the flu, you should feel better after one or two weeks. But in some people, the flu leads to serious, even life-threatening diseases, like pneumonia. Some people are more likely to get the serious complications. A vaccine (the flu shot) is recommended for these high-risk people to protect them from the flu.
Who is at higher risk?
You have a higher risk of flu complications if you:
If you are in any of these risk groups, you should get the flu vaccine every year.
Even if you're not at higher risk, you may want to get the flu vaccine so you don't get sick with the flu.
What is the flu vaccine?
The flu vaccine is an injection. It contains killed viruses. You can't get the flu from the vaccine because the viruses are dead. Instead, the vaccine protects you from the flu. When a "live" virus shows up, your defenses are ready. These defenses keep you from getting the flu. Because flu viruses change from year to year, you must get the shot each year to be protected.
When should I get the vaccine?
You should get the vaccine at the beginning of the flu season, sometime in September onwards. You can get the shot later in the year too, but because flu season usually begins in the winter months, it would be best to be protected before that time.
If I get a flu shot, can I still get the flu?
Yes. Even with a flu shot, you aren't 100 percent protected. Each year, the flu vaccine contains three different strains (kinds) of the virus. Depending on the strains used, the Flu vaccine is 70 to 90 percent effective in preventing the flu in healthy people under 65 years of age. If you're older than 65, the vaccine is less likely to prevent the flu. Even if you get the flu after the vaccine, your flu symptoms should be milder than if you didn't get the vaccine. You'll also be less likely to get complications from the flu.
Is the vaccine safe?
Yes. The flu vaccine is safe for all age groups over six months of age. There are very few side effects too. Your arm may be sore for a few days. You may have a fever, feel tired or have sore muscles for a short time. If you have a severe allergy to eggs, you shouldn't get the shot.
Do you take the FLU vaccine?
Yes, I have personally been taking the FLU vaccine for the last 3 years, ever since it was made available in
Will the vaccine be effective against swine flu?
As of now we do not really know, however we must remember that Seasonal Flu kills far more people than Swine Flu, and it is as serious a disease. For the high risk people mentioned above, taking this vaccine is a great way to reduce complications from this common disease.

What are the symptoms?
Swine flu symptoms are similar to the symptoms of regular flu and include fever of over 100.4°F, fatigue, lack of appetite, and cold. Some people with swine flu have also reported runny nose, sore throat, nausea, vomiting and diarrhoea. Nearly everyone with flu has at least two of these symptoms.
So, how do you know if you have flu or just cold?
There is one clue: when you have the flu, you feel flu symptoms sooner than you would cold symptoms, and they come on with much greater intensity. With the flu, you may feel very weak and fatigued for up to 2 or 3 weeks. You'll have muscle aches and periods of chills and sweats as fever comes and goes. You may also have a stuffy or runny nose, headache, and sore throat.
Can I compare flu symptoms with cold symptoms?
Yes. The following chart can help you compare flu symptoms with cold symptoms. Use it to lean the differences and similarities between flu and cold symptoms. Then, if you get flu symptoms, call your doctor and ask about an antiviral drug.
| Symptoms | Cold | Flu |
| Fever | Rare | Characteristic, high 100-102 degrees F); lasts 3-4 days |
| Headache | Rare | Prominent |
| General aches, pains | Slight | Usual; often severe |
| Fatigue, Weakness | Quite mild | Can last up to 2-3 weeks |
| Extreme Exhaustion | Never | Early and prominent |
| Stuffy Nose | Common | Sometimes |
| Chest Discomfort, Cough | Mild to moderate; mild cough | Common; can become severe |
You cannot confirm if you have swine flu just based on your symptoms. Like seasonal flu, pandemic swine flu can cause neurologic symptoms in children. These events are rare, but, as cases associated with seasonal flu have shown, they can be very severe and often fatal.
Doctors may offer a rapid flu test, but what you need to understand is a negative result doesn't necessarily mean you don't have the flu. Only lab tests can definitively show whether you've got swine flu. State health departments can do these tests.

Antiviral drugs can be used to treat swine flu or to prevent infection with swine flu viruses. The anti-viral medicines oseltamivir (Tamiflu) and zanamivir (Relenza) are being used to treat people with swine flu. Antiviral drugs work by preventing the flu virus from reproducing. To be effective you need to take them within 48 hours of the symptoms beginning. These flu drugs can decrease the duration of the flu by 1 to 2 days if used within this early time period. These antivirals are usually given for a period of about 5-7 days. It's unclear whether these drugs can prevent complications of the flu. Tamiflu is approved for prevention and treatment in people 1 year old and older. Relenza is approved for treatment of people 7 years old and older and for prevention in people 5 years old and older. These medications must be prescribed by a health care professional.
Side effects: Side effects of antiviral drugs may include nervousness, poor concentration, nausea, and vomiting. Relenza is not recommended for people with a history of breathing problems, such as asthma, because it may cause a worsening of breathing problems. Discuss side effects with your doctor.
Self medication: Antibiotics are a no-no. Chances are that antibiotics will not help your flu symptoms. That's because flu, colds, and most sore throats and bronchitis are caused by viruses. In addition, taking antibiotics when you have a virus may do more harm than good. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment. Antibiotics only cure certain infections due to bacteria -- and if taken carelessly, you may get more serious health problems than you bargained for.
Is there a vaccine to treat swine flu virus?
No, there isn’t a vaccine yet. But vaccines are being made in large quantities. Clinical tests will begin in August 2009. Depending on how long federal officials wait for the results of these tests, tens of millions of doses of swine flu vaccine could be ready as soon as September 2009, with more vaccine becoming available each month thereafter. The first doses of vaccine likely will go to pregnant women and young children ages 6 months to 4 years, with older school kids to follow.

Those who are more at risk from becoming seriously ill with swine flu are people with:
The new swine flu virus is highly contagious, that is it spreads from person to person. The virus is spread through the droplets that come out of the nose or mouth when someone coughs or sneezes. If someone coughs or sneezes and they do not cover it, those droplets can spread about one metre (3ft). If you are very nearby you might breathe them in.
Or, if someone coughs or sneezes into their hand, those droplets and the virus within them are easily transferred to surfaces that the person touches, such as door handles, hand rails, telephones and keyboards. If you touch these surfaces and touch your face, the virus can enter your system, and you can become infected.

Influenza antiviral drugs also can be used to prevent influenza when they are given to a person who is not ill, but who has been or may be near a person with swine influenza. When used to prevent the flu, antiviral drugs are about 70% to 90% effective. When used for prevention, the number of days that they should be used will vary depending on a person’s particular situation.
Follow this general procedure to reduce the risk of catching or spreading the virus, you should:
Information on the effectiveness of facemasks and respirators for decreasing the risk of influenza infection in community settings is extremely limited. So, it is difficult to assess their potential effectiveness in decreasing the risk of Swine Flu virus transmission in these settings. However, a well-fitted, FDA-approved mask together with other preventive measures MAY reduce the risk of contracting the flu. Those who are sick or caring for someone who is ill should consider using a mask or respirator if leaving the house becomes necessary.

Two things - soap and water can reduce the chance of infection by 30 per cent. All you need to do is keep washing your hand with soap and water frequently. Wash hands frequently with soap and water or use alcohol-based hand cleaner when soap and water are not available. Avoid touching your eyes, nose and mouth
Eat healthy: Proteins are essential to help your body maintain and build strength. Lean meat, poultry, fish, legumes, dairy, eggs, and nuts and seeds are good sources of protein.
The Food and Drug Administration recommends that adults eat 50 grams of protein per day. Pregnant and nursing women need more. By eating foods high in protein, we also get the benefit of other healing nutrients such as vitamins B6 and B12, both of which contribute to a healthy immune system.
Vitamin B6 is widely available in foods, including protein foods such as turkey and beans as well as potatoes, spinach, and enriched cereal grains. Proteins such as meats, milk, and fish also contain vitamin B12, a powerful immune booster.
Minerals such as selenium and zinc work to keep the immune system strong. These minerals are found in protein rich foods such as beans, nuts, meat, and poultry.
Exercise: Regular exercise may help prevent the flu. According to recent findings, when moderate exercise is repeated on a near daily basis, there is a cumulative immune-enhancing effect. That is, your strong immune system can fight flu better. When you exercise, your white blood cells -- the blood cells that fight infections in the body -- travel through your body more quickly, fighting bacteria and viruses (such as flu) more efficiently. To maintain good health, experts recommend at least 30 minutes of aerobic activity such as walking, swimming, biking, or running each day.

What precautions should one take at schools?
There is NEVER a need to PANIC. With the below mentioned common answers, you should be able to feel more confident about Swine Flu, especially in the Indian context. The media hype in this regard needs to be ignored.
So what are the common SWINE FLU SYMPTOMS?
The symptoms of swine flu are essentially indistinguishable from the familiar misery of seasonal flu: fever, coughing, sore throat, body aches, headache, sometimes vomiting and diarrhea. So which of us need to contact the doctor?
If you have traveled abroad to a country with a large number of Swine Flu cases in the last two weeks, and have Flu like symptoms.
OR
If you have personally met someone who was later diagnosed to have Swine Flu in the last two weeks, & you have flu like symptoms.
Only under these circumstances do you need to worry about Swine Flu in
How can I prevent SWINE FLU?
Just like regular seasonal flu virus, the swine flu virus is thought to spread on droplets emitted by coughing and sneezing or deposited on hands and surfaces, then transferred to nose or mouth. Thus, practicing the usual precautions will help prevent its spread:
* Use a tissue when you cough or sneeze, and throw it away promptly. If you don’t have a tissue, cough into your sleeve.
* Wash your hands thoroughly and often, especially after sneezing or coughing, using soap and water or an alcohol rub. I personally use non alcoholic hand sanitizer by Himalaya Pharmaceuticals called Pure Hands, this is easily available with your local chemist shop. Any good hand sanitizer would do.
* Wipe surfaces like doorknobs using a regular cleaner.
* If you’re sick with flu-like symptoms, even if you don’t feel sick enough to go to the doctor, stay home from work or school to avoid giving the virus to someone else.
The most effective way to prevent Swine Flu is by STAYING at HOME, and by regular hand washing.
Please remember that as of now there is no vaccination (though one is likely to be available by the end of 2009 or sooner), antiviral medicines are generally not needed, and the disease is generally mild in most people.
When do I need to go to the Hospital?
If you have breathing problems, then you need to go the Emergency Room. Rest, Plenty of Warm Fluids, and mild OTC medications for Fever like Crocin, Brufen etc. should help you recover within 5-7 days.

How important is Swine Flu really?
Is it likely to be a pandemic?Is it going to kill millions of people like the infamous flu pandemic of 1918?
Unfortunately no one has the answers. Lots of speculations, guesses, and opinions. However a few regularly asked questions that have specific answers are what I am going to answer here, and provide a couple of excellent resources for self reading.What are the symptoms of Swine Flu? Symptoms include at least 2 of the following:
In addition, persons with swine flu may have other typical symptoms of influenza, including body aches, headache, chills, fatigue, and possibly diarrhea and vomiting.
Can you get this from eating cooked pork? No.Can my pets get this? No.
Should I avoid traveling to swine flu affected areas at present ? Yes if you can avoid it.Should I postpone my trip to US/ Mexico? It's too soon to know; follow travel-advisory information from the CDC closer to the event.
Will there be a vaccine? Work is under way to make a safe and effective vaccine that hopefully will be available by next flu season.Is there enough medication? For those who may truly need it, yes, but most infected persons in the United States & worldwide (except Mexico) have not required intensive medical intervention.
What should I do to protect myself and my family? Take these everyday steps to protect your health:I am planning to travel to USA, what should I do? Avoid it if possible, otherwise take regular precautions like washing hands, covering mouth and avoid crowded places and report to a doctor if you have flu like symptoms. Talk to your doctor about carrying Tamiflu as a preacutionary measure if traveling to an area with high incidence of Swine Flu.
So the answer to that question is NO, if you are a healthy person traveling to USA, you may not take prophylaxis, because the risk of serious disease is virtually negligible.
What is the dose for Tamiflu? Tamiflu is NOT recommended for children less than 1 year. While a syrup form is available in the USA, I believe that none is available in India.
The dose is 2.5 mg/kg twice a day for treatment, while it is 2.5 mg/kg once a day for prophylaxis. For adults the dose is 75 mg once a day for prophylaxis and twice a day for treatment.
Here are a few excellent resources that will provide updated information about Swine Flu.
Medscape Resource Center for CliniciansThis weekend I had a interesting presentation on Rotavirus presentation in our local IAP (Indian Academy of Pediatrics) meet of Pediatricians of Chandigarh, Panchkula & Mohali tri-city.
What is the rotavirus? Just the commonest cause of diarrhea in children, killing more than 1 lakh children in India alone!
You can get the entire presentation here. It was fun to read up this disease, since in office practice I tend to not get in a lot of academic reading about specific illnesses. While I am using the presently only available Rotavirus vaccine (Rotarix by GSK), there were still a few surprises for me. The large number of deaths worldwide caused by this virus were astounding, more so the fact (as you can read in the presentation ) that India has the largest number of deaths by far.
Since the presentation, I would probably be a bit more aggressive in suggesting this vaccine to affording parents with children under the age of 6 months. While the vaccination is at present slightly expensive (around INR 1,000 - 1,500 per dose), since it is imported and being marketed by a multinational, an Indian Rotavirus Vaccine is likely in the next few years, making a serious dent to the large number of preventable deaths due to rotavirus.
Being a doctor I always feel that there would be less chances of misdiagnosis in my case. I know the doctors, their reputation, and many are friends too. So this weekend when I developed pus in my tonsils, I first took a course of "mild" antibiotic Azithromycin. Since that did not work, I talked to an ENT specialist friend, and he recommended a course of Clindamycin, after having a look and saying that I had a lot of pus in both the tonsils. For those of you who have taken this medicine, you know the gastritis, loose motions etc. that are a part and parcel of taking it. However, I did take this as directed. However after 3 days of continuously missing my clinic practice due to fever, body aches and general malaise, I got a second opinion from another ENT specialist today. He had a look, and immediately exclaimed that this is a VIRAL tonsillopharyngitis, and it would recover faster with just a short course of oral steroids. No need for any antibiotics! This was amazing, and I am starting to feel better already :-)
I asked him and searched online for tips regarding how to differentiate the two conditions, since we do get a lot of purulent tonsillitis in my pediatric practice too.
While of course there are no hard and fast rules, generally viral tonsillitis would have small ulcers else where too, other than the tonsils, and the tonsils would not be angry red or enlarged. There would be more pain during speaking, and lots of malaise, but not very high fever nor toxic look in cases of children with viral tonsillitis. Small ulcerations on the other areas of the throat would be pathognomonic for viral tonsillitis, though in cases of doubt, a simple blood count would help differentiate the two conditions. Scratchy feeling in the throat, and other symptoms like cold, cough etc. are likely to occur. Generally the neck lymphnodes are not significantly enlarged nor painful in viral pharyngitis. Viral purulent tonsillitis is less common in children, and starts appearing in teenagers and older adults.
Strep tonsillitis is the most important differential between commonly occurring between 3-15 years age. Bacterial pharyngitis generally has higher fever, no flu like symptoms, and painful enlarged lymphnodes. There may be a petechial rash over the palate / uvula. Strep throat swabs are not easily available / routinely used in India at present, though this is likely to change, so immediate diagnosis is not possible, and antibiotics are generally given to everyone with purulent tonsillitis.
Well a lesson learnt about viral / bacterial tonsillopharyngitis, and that even simple conditions can be misdiagnosed leading to unnecessary suffering and missed work. While we do read about this, it really hits home when it happens to you I guess!
The other thing that I realized was that even for a "trivial" illness like tonsillitis, finding a better doctor can make such a difference, imagine how much difference it would make for serious and life threatening diseases?!
