a disease that has a steady frequency over time in a particular geographic location is


Like the disease of the past, the disease of the present and the future is a constant process, but in an ongoing way.

You know when you’ve had a cold for a day or two and then you feel bad about it, but you don’t want to go to a doctor because you’ve already had the flu? You have the flu. The flu is a disease that can be triggered by a single exposure, and it’s caused by a particular strain of flu virus that’s known as flu A or flu B. Flu A and flu B are the same strain, and there are two different types of flu viruses.

The flu is caused by an infection with a type of flu virus in the digestive system. The flu virus that causes the flu, also causes a new type of flu called influenza A. This flu virus has caused pandemics in the past and so has caused the occasional flu epidemic in the past. It can also be spread by the cough, sneeze, or touch of contaminated surfaces. The flu A also has a particular mutation that gives it immunity against influenza A.

In the case of the flu, the current strain, that we’re talking about today is called H3N2. The H3N2 strain mutates so that it becomes resistant to the H3N2 flu virus. The H3N2 strain also mutates so that it becomes susceptible to influenza A. Both strains of flu virus are considered “potentially fatal” and when the flu virus hits our body it can cause severe illness and even death.

The flu is a very dangerous disease. The current flu strain was first identified in the fall of 2013 and has a lot of people who are very worried. Since the flu virus mutates so quickly, it’s not always easy for us to track new flu strains or find out how they are affecting our lives. The flu virus is also a potential carrier; the flu virus can enter our bodies if we don’t wash our hands or cover our nose and mouth.

Flu is a difficult virus to track because it mutates so quickly and can be spread in many different ways. The flu virus mutates a lot but it can still spread in a predictable way. For example, there is a vaccine that can protect us from the flu virus but it requires the proper handling and hygiene to work. The flu virus mutates and becomes even harder to prevent.

As some of you may know there are lots of different types of flu viruses and each one can mutate differently. Some can mutate into a flu virus that would make you sick much sooner than if a flu virus from a different type was present. You can get the flu virus even if you’re already exposed to the flu virus.

My wife and I spent a few days with a viral, pandemic flu virus in our house. We didn’t know who it was because we were on the floor with no idea of what that virus was. It was pretty obvious that it was a pandemic flu virus and people were just thinking, “I’ve seen it before in my house.” I just watched it and I knew it wasn’t a pandemic flu. It’s just another of those things that really makes a big difference.

The pandemic flu virus was pretty bad actually. The CDC estimates that it caused at least 2 million deaths during the 1918 flu pandemic, with close to 50 million people infected with the virus. That’s approximately 10% of America’s population.
