In 2009 a deadly virus

In the spring of , a novel influenza A H1N1 virus emerged. It was detected first in the United States and spread quickly across the United States and the world. This new H1N1 virus contained a unique combination of influenza genes not previously identified in animals or people.

This virus was designated as influenza A H1N1 pdm09 virus. Ten years later work continues to better understand influenza, prevent disease, and prepare for the next pandemic. The H1N1 pdm09 virus was very different from H1N1 viruses that were circulating at the time of the pandemic.

Few young people had any existing immunity as detected by antibody response to the H1N1 pdm09 virus, but nearly one-third of people over 60 years old had antibodies against this virus, likely from exposure to an older H1N1 virus earlier in their lives.

Since the H1N1 pdm09 virus was very different from circulating H1N1 viruses, vaccination with seasonal flu vaccines offered little cross-protection against H1N1 pdm09 virus infection.

While a monovalent H1N1 pdm09 vaccine was produced, it was not available in large quantities until late November—after the peak of illness during the second wave had come and gone in the United States.

Additionally, CDC estimated that ,, people worldwide died from H1N1 pdm09 virus infection during the first year the virus circulated. This differs greatly from typical seasonal influenza epidemics, during which about 70 percent to 90 percent of deaths are estimated to occur in people 65 years and older. Though the flu pandemic primarily affected children and young and middle-aged adults, the impact of the H1N1 pdm09 virus on the global population during the first year was less severe than that of previous pandemics.

One of the biggest differences between the two is that bacteria can be treated with antibiotics, while viruses cannot due to their small size and the fact that they reproduce inside of the cell.

Viruses can be managed with medicines, but there is no cure for them, although viruses can be prevented with vaccines. Once symptoms of rabies start to appear, it is too late and the disease will be fatal.
