There are only two more parts to this series, so it will end next Wednesday. I will then move on to other topics. I hope you are finding this series useful.
The 5th link in the Chain of Infection is the Portal of Entry. A portal of entry can be broken skin, incisions, inhaled through the respiratory tract. There are a few others, but since we are discussing cold and flu these are the ones we will discuss.
You may have noticed a pattern by now that good handwashing is included in almost every chain in the link. Good handwashing is the number one way to prevent cold and flu. Barriers such as gloves and respiratory masks are two other ways to break this link. BTW gloves and respiratory masks do not just protect you from getting a cold or flu, but protects others from you should you be the person with the illness. I think sometimes people forget this. Also getting a flu shot if you have been advised to do so can break this link. Basic First Aid and personal hygiene are the last two ways to break this link. If you have overly chapped hands, or small cuts on your hands, that can allow germs to enter be sure and use a hand lotion to help heal the skin. Chapped, dry lips and nose can also allow germs to enter. Use chapstick, and a humidifier at night to add moisture and barrier to protect against germs entering the body. Get at least 7-8 hours of sleep and maintain a healthy diet will also help keep you and your Immune System in good working order.
