What is a virus? How do viruses work?

What is a virus and how do they work? In the first video in the series, WinchPharma Science & Health examines viruses, how they infect cells and reproduce, and their practical uses.



  1. +WinchPharmaGroup #3:24 you laughed out

  2. 3:35 "HIV used to cure cancers"

  3. HIV is the cure to cancer…

  4. lol wtf virus can replecat it self

  5. Nah, it is virtually impossible for a nucleus to be generated by "accident" simply by random means of infecting a host. No real research done on it, otherwise… well, we would see that remarkable breakthrough all around! I'm serious, many, many doctors, as they study and go into detailed research on the human body, see a link to a "creator" in the grand scheme of things. Not preaching or being a religious nut, just sharing a little bit of info.

  6. very useful and very education so thanks very much

  7. Why do viruses exist in the first place? … Do you think life on Earth can live without viruses???

  8. Im sick and i do have a virus in my throat (i dont mean virus on a computer)

  9. What is the name of the song at the end of the video?

  10. What kind of animation is this? Hoe can i create it?

  11. Hello. The National Autonomous University of Mexico is making a MOOC about the abuse of antibiotics, and this video could be very useful. How can we get your approval. Thank You!

  12. Ok I’m doing this cause of school

  13. Viruses cannot self-replicate!

  14. I’m inhaling this shit every second of my life… WHO NEEDS TO GO OUTSIDE ANYWAYS

  15. What is virus?

    Virus is zombie bacteria

  16. 0:59 saying that they are able to self-replicate is kind of misleading. The need the machinery of cells in order to replicate.

  17. All Viruses should be INCINERATED in a nuclear reactor; worthless pieces of DNA/RNA that cause senseless suffering to billions.
