The flu season of 2018 is one of the worst that has been recorded. After several deaths and hospitalizations in almost every state, there are some facts that you need to know about the virus so that you stay healthy. Officials often ask that people get a flu vaccine starting in October. The newest vaccine that has been developed is normally available at this time. The worst season that has been recorded was in 2014-2015. However, the 2018 season is seen as among the worst because of how early it started and just how many states that the virus has impacted. There are usually a few different strains of the flu that circulate each year. One strain can sometimes mutate, which is what has happened in 2018. The H3N2 virus is one of the more severe strains and is responsible for more deaths and long-term hospitalizations than other strains of the flu virus. The flu vaccine is usually only about 30 percent effective with this type of strain or with other strains that have mutated during the season. Washing your hands is suggested to keep the spread of the virus to a minimum, but staying away from other people while you’re sick is often the best way to prevent the spread of the virus.
