So far we have had a very cold winter in most of the US. However, still to date there has not been a major H1N1 outbreak. Albama was the only state to have a widespread H1N1 outbreak. You can track H1N1 outbreaks by tracking H1N1 updates.
There are several reasons for the H1N1 not spreading. The first reason is that H1N1 outbreak has been somewhat contained. The virus has not spread very rapidly as once believed. The virus was discovered sometime last year. Doctors were afraid that the virus may mutate. This mutation could be very dangerous. However, it looks like a dangerous mutation of this virus does not exist as of now.
Another reason the H1N1 has not been widespread as of yet is because it may have not peaked. The flu season can be variable. This flu season may last for several more months so an outbreak is still possible. It is still wise to use the same precautions as always with this flu virus.
The final reason for the H1N1 not spreading is awareness. Most people are not panicking about H1N1. People are using precautions such as washing their hands, not going around sick people and covering their noses when they sneeze. These small little steps really help contain the virus which can help an epedemic from occuring.
Vaccinations are important to people at risk. However, the vaccinations have not proven to do anything to contain the H1N1 virus. The vaccinations have been slow to arrive. They have not been delivered rapidly in the US as well. Most people in the US are still not vaccinated against the H1N1 virus.
