The arrival of winter signals many things--the holidays, the New Year and unfortunately for tens of thousands of Americans, the onset of flu season. The flu is unpredictable and how severe it is can vary from one season to the next depending on many things such as:
- Which influenza virus is spreading
- How much flu vaccine is available
- When the vaccine is available
- How many people get vaccinated
- How well the vaccine is matched to particular strains of influenza viruses
Certain people are at greater risk for serious complications if they get the flu. This includes seniors, young children, pregnant women and people with certain health conditions such as asthma, diabetes or heart disease.
Flu seasons are unpredictable and can be severe. Over a period of 30 years, between 1976 and 2006, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people.
At Interim HealthCare and for our thousands of patients who receive our in home senior care, the single best way to prevent the flu is to get a flu vaccine each season. While there are two types of flue vaccines (flu shots and nasal spray), seniors 65 and older should receive a high-dose vaccine, which is injected usually in the upper part of the arm. This vaccine was first made available during the 2010-2011 season.
About two weeks after vaccination, antibodies develop that help protect against influenza virus infection. Flu vaccines however will not protect against flu-like illnesses caused by non-influenza viruses.
Yearly flue vaccines should begin in September or as early as the vaccine is available. While a flu vaccine can help protect seniors in the long run, you should always take everyday preventative actions including covering coughts, washing hands often, and avoiding people who are sick.
According to the Centers for Disease Control, it's estimated that 90 percent of seasonal flu-related deaths and more than 60 percent of seasonal flu-related hospitalizations in the United States each year occur in people 65 years and older. This is because human immune defenses become weaker with age, which means influenza can be a very serious disease for seniors.
