I was surprised because there are a lot of flu viruses. I learned about flu vaccine needed every year because the virus is constantly changing from the lecture. I also became knew that vaccine is formulated each year to keep up with change. I was not realized the flu shot can protect infection by preparing my body. Good job!
Hi Shockley,
I learned about droplet transmission means the large particles from the one person are passed to the susceptible person from the lecture. In droplet transmission, the infected particle are large and can travel about three feet. So I need to teach my children to cover their moths when they cough or sneeze. That is very important people to protect the virus can be spread. Good job!
