Swine flu

1976: The swine flu scare

On the cold afternoon of February 5, 1976, an Army recruit told his drill instructor at Fort Dix that he felt tired and weak but not sick enough to see military medics or skip a big training hike.
Within 24 hours, 19-year-old Pvt. David Lewis of Ashley Falls, Mass., was dead, killed by an influenza not seen since the plague of 1918-19, which took 500,000 American lives and 20 million worldwide.
Two weeks after the recruit's death, health officials disclosed to America that something called "swine flu" had killed Lewis and hospitalized four of his fellow soldiers at the Army base in Burlington County.

What is swine flu?

Like people, pigs can get influenza (flu), but swine flu viruses aren't the same as human flu viruses. Swine flu doesn't often infect people, and the rare human cases that have occurred in the past have mainly affected people who had direct contact with pigs. But the current "swine flu" outbreak is different. It's caused by a new swine flu virus that has changed in ways that allow it to spread from person to person -- and it's happening among people who haven't had any contact with pigs.

Swine Flu Symptoms:

fever, which is usually high, but unlike seasonal flu, is sometimes absent

cough

runny nose or stuffy nose sore throat

body aches, headache

chills

fatigue or tiredness, which can be extreme

diarrhea and vomiting, sometimes, but more commonly seen than with seasonal flu

Signs of a more serious swine flu infection might include pneumonia and respiratory failure.
If your child has symptoms of swine flu, you should avoid other people and call your pediatrician who might do a rapid flu test to see if he has an influenza A infection. Further testing can then be done to see if it is a swine flu infection.

Swine Flu High Risk Groups:

With regular seasonal flu, infants and the elderly are usually thought to be most at risk for serious infections, in addition to people with chronic medical problems. Swine flu high risk groups, people who are thought to be at risk for serious, life-threatening infections, are a little different and can include:
pregnant women

people with chronic medical problems, such as chronic lung disease, like asthma, cardiovascular disease, diabetes, and immunosuppression

children and adults with obesity

Serious Swine Flu Symptoms:

More serious symptoms that would indicate that a child with swine flu would need urgent medical attention include:
Fast breathing or trouble breathing

Bluish or gray skin color

Not drinking enough fluids

Severe or persistent vomiting

Not waking up or not interacting

Being so irritable that the child does not want to be held

Flu-like symptoms improve but then return with fever and worse cough

What You Need To Know?

Swine flu likely spreads by direct contact with respiratory secretions of someone that is sick with swine flu, like if they were coughing and sneezing close to you.

People with swine flu are likely contagious for one day before and up to seven days after they began to get sick with swine flu symptoms.

Droplets from a cough or sneeze can also contaminate surfaces, such as a doorknob, drinking glass, or kitchen counter, although these germs likely don't survive for more than a few hours.

Anti-flu medications, including Tamiflu (oseltamivir) and Relenza (zanamivir), are available to prevent and treat swine flu.
