Flu activity around the United States is low now, but expected to pick up in the coming weeks, according to the Centers for Disease Control. The time to get vaccinated, according to the CDC, is now.
Last flu season, an estimated 49 million Americans contracted influenza with 960,000 needing hospitalizations due to the illness and 79,000 deaths attributed to flu-related causes.
How does the flu spread?
Flu viruses are thought to spread mainly from person to person through droplets made when people with flu cough, sneeze, or talk. Flu viruses also may spread when people touch something with flu virus on it and then touch their mouth, eyes, or nose. Many other viruses spread these ways too. Persons infected with flu may be able to infect others beginning 1 day before symptoms develop and up to 5-7 days after becoming sick.
That means you may be able to spread the flu to someone else before you know you are sick as well as while you are sick. Young children, those who are severely ill, and those who have severely weakened immune systems may be able to infect others for longer than 5-7 days.
How do I know if I have the flu?
The flu usually comes on suddenly. People who have the flu often feel some or all of these symptoms: fever or chills, coughing, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue. Sometimes people with the flu can have vomiting and diarrhea, although this is more common in children than adults. If you or someone you know is sick with some of these symptoms they should consider getting medical attention, especially if they are at high risk of complications. People at high risk of
complications include children under five years-old, adults 65 years-old or older, and pregnant women.
What about the vaccine?
There is plenty of it with more than 148.2 million doses having been distributed in the United States.
There are no shortages – see your healthcare provider, one of the clinics listed below, or pharmacy.
The bad news is: 3 out of every 5 members of the general population are unprotected, with Nevada having the lowest rates in the nation
– For pregnant females, the rate is 35.6%. They are at higher risk of complications, especially in the second and third trimester, as are their newborns, who cannot be vaccinated until 6 months of age.
– The effectiveness of the vaccine is lower this year, estimated to be 32% against the H3N2 strain, but could be as low as 10%. The average effectiveness between 2006-2017 is 46% (as low as 19% in 2014-15, with a high of 60% in 2010-11.)
However, getting vaccinated is still the single most important and effective measure one can take to prevent illness, hospitalization, or death from influenza.
What about antiviral medication, such as Tamiflu?
If you get the flu, there are prescription antiviral drugs that can treat your illness. Early treatment is especially important for the elderly, the very young, people with certain chronic health conditions, and pregnant women.
What are everyday preventive actions?
– Try to avoid close contact with sick people.
– If you or your child gets sick with flu-like illness, we recommend that you (or your child) stay home for at least 24 hours after the fever is gone except to get medical care or for other necessities. The fever should be gone without the use of a fever-reducing medicine.
– While sick, limit contact with others as much as possible to keep from infecting them.
– Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
– Wash your hands often with soap and water. If soap and water are not available, use an
alcohol-based hand rub.
– Avoid touching your eyes, nose and mouth. Germs spread this way.
– Clean and disinfect surfaces and objects that may be contaminated with germs like the flu.
It is not too late to get your flu shot. Vaccination is still the best protection against the flu and your individual flu shot serves as your contribution to community wellness. It will help protect the elderly and all babies under 6 months old who are too young to be vaccinated, as well as the vulnerable in our community with cancer, respiratory illnesses, and weakened or compromised immune systems. Your efforts help build Community Immunity.
