What true statements can you give about biological viruses?

Answer 1

True statements about biological viruses include that viruses:

• need a host to reproduce
• hijacks the body's cells to support the virus
• are easily transferable to others
• have no known cures
  
• most are self-limiting (end within 10-21 days), but some (AIDS, HIV) become lifelong illnesses
• sickens the host through proteins the virus produces
• weakens the immune system, making it easier to catch other infections
• have killed billions worldwide throughout history, especially the flu which led to pneumonia
• do not respond to antibiotics, though wide-spectrum preventative antibiotics may help reduce risk of bacterial infections for high risk groups (young, elderly, pregnant women)
• people with general viruses (cold, flu) overuse antibiotics, which in otherwise healthy people are NOT needed
• easily change their structure from year to year, making them hard to combat with vaccines
• have few vaccines, and each virus requires a vaccine specific to that virus
• the flu virus has had the longest trend of preventative vaccines, more than any other virus
• scientists work year round to break the code to understand how to interrupt a virus's replication; studies may go on for years to get only 1 piece of useable information
• viruses will exist as long as hosts exist
• 
  

Answer 2

Viruses can not reproduce by themselves.
