Warm Up March 2 nd, )Viruses are non-_______. They also will attack and use other organisms to reproduce. What good could a virus do? 2)What is a bacteriophage (hint: type of virus)? 3)How does your immune system fight viruses? What is so problematic about AIDS/HIV?

Virus* - Non-living particles made of either DNA or RNA and a protein coat. - Need a host to reproduce. - Invade cells and use them to reproduce viruses, killing the cell. - Disease from viruses account for most illness in humans.

Chicken Pox -Fairly benign -Only get once in your life (body produces antibodies) -Can lead to ‘Shingles’ later in life.

Chicken Pox - Varicella Chicken Pox Shingles

Rabies -Affects brain and central spine. -A classic rabies sign in animals is if they become unafraid of humans (wild). Bats most likely to give you rabies. -Humans become comatose after getting rabies if not treated (followed by death), there is no zombie rabies biting going on.

Rabies

Dengue Fever – Breakbone Fever -Spread by mosquitoes. Most effective way to stop it, is not get bit by mosquitoes…. -Signs are a skin rash similar to measles. -Serious cases can cause death from bleeding and lower blood cell counts. Most common in tropical locations (Pacific islands, Latin America).

Dengue Fever – Breakbone Fever

Why are else are VIRUSES so dangerous? 1.They can lie and wait for days, weeks, even years before springing to action. 2.Once you’re infected, they spend most of their time HIDDEN INSIDE your cells. 3.They not only are in your cells, but their instructions can mess up YOUR genetic DNA = CANCER!. 4.There’s a lot of different viruses out there. 5.Anything that can kill BACTERIA is dangerous; those specific viruses are called Bacteriophages!
