The current H1N1 virus bears a close resemblance to the 1918 H1N1 virus, called Spanish flu, which reached most parts of the world and killed between 50 million and 100 million people, most of whom were healthy young adults. Medical experts agree, however, that today's H1N1 virus is not nearly as lethal as the 1918 virus. According to the Centers for Disease Control and Prevention (CDC), H1N1 is a pandemic, meaning it is a global epidemic. The virus is a serious threat to even healthy people, causing bacterial pneumonia in some. The virus can be readily transmitted across 10 feet, putting people at risk at any gathering. According to the CDC, there are actions that can reduce exposure to the virus. This includes covering your nose and mouth with a tissue when coughing or sneezing and then throwing the tissue in the trash. Hands should be washed often with soap and water, with antibiotic soaps if possible. Alcohol-based hand rub or sanitized "germ killer" wipes can also be used. Avoid touching your eyes, nose, and mouth. If sick, stay home and limit contact with others. First responders, including law enforcement officers, should have high priority for receiving the H1N1 vaccine, but it should not be mandated by police agencies. Officers with symptoms must be sent home. Agencies should also provide training to personnel in the nature, prevention, and treatment for H1N1, and backup plans should be developed in the event the work force is weakened by a high number of absentees due to illness.
