Influenza
Today wraps up National Influenza Vaccination Week here in the United States and with that I am writing today to discuss what is influenza and what does it do. I know there continues to rage a national debate as to the effects and to the safety of the Flu vaccines and today I’m not going to dive into that debate, I just want to talk to you about the different flu bugs that are out there and let you make up your own mind.
The history of influenza (commonly called the flu) is one that is full of speculation, uncertainty and death on a huge scale. The first documented recognition of influenza was in 1918 by veterinarian S. J. Koen who was studying the effects of an illness in swine which was very similar to the illness that was ravaging the globe at that time. It wasn’t until 1933 that the actual flu virus was identified by scientist and then the true history of the bug started to become clearer. It is believed that influenza has been around for thousands of years and is thought to have originated from animals that where first domesticated and then mutated to afflict human hosts as well. Over time there have been mutations of the various flu strains that have cause world-wide pandemics the most famous being the 1918 flu pandemic where it is estimated that the death toll for that strain of H1N1 was close to 100 million people. Influenza typically causes fatalities of the very young or the very elderly but the strain that hit in 1918 attacked those in the prime of their life between the ages of twenty to forty and left the young and elderly mostly alone.
There are three basic flu types; type A, B and C and there are several strain of each type. Humans are susceptible to both the A and B types of the flu while type C is usually found only in animals. What we see here in the United States every flu season is typically a strain of type A flu and thus most of the vaccinations that are produced each year are geared for this type of flu. Occasionally there is a mutation of a particular strain and there will be an outbreak with a higher mortality rate than typical. The last such outbreak in the US was in 2009 when there was the H1N1 scare. Ironically, H1N1 is a common flu strain, it just had mutated and therefore it was a stronger bug in 2009. According to the Center for Disease Control data for 2014, over 4,500 people died as a direct result of influenza. The true number of death caused by the flu is hard to really calculate as many times it is not listed as a cause of death when a death is reported. What makes the flu especially dangerous is that it weakens to respiratory system to the point where pneumonia becomes a high risk for people of a certain age which then leads to death.
The flu can be confused with the common cold sometimes as not all flu bugs will cause vomiting. Symptoms of influenza are fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches and fatigue. Symptoms of the common cold are usually milder than the symptoms of flu as people with colds are more likely to have a runny or stuffy nose. If you are not sure what ails you, see you family doctor and take precaution. It’s always important to hydrate when you have the flu (or any illness) as dehydration can also wreak havoc on the body as well which can make you feel even worse.
As we sail into the height of flu season, I urge you to take care, talk to your doctor and see how best to protect yourself and your loved ones. The very young and the elderly (as well as those with other medical issues) are all especially vulnerable so please take precaution. As we move closer to Christmas and the New Year, I hope everyone takes their time and enjoy the company of friends and family. Take care of yourself and each other, remember, we’re all in this together.
