viruses are difficult to resist as their are many anti biotics as u may have learned bt fr the viruses our immune system must be strong enough to defeat the same. a person whose immune sys. is weak a small virus can affect him badly

 

for q2 ) they do not fool our immune sys. they are jst more powerful when a virus enters our body our body produces some anti bodies to fight against these viruses which act like soldiers who recieve commands from brains to kill the viruses

Both viruses and bacteria can be equally difficult for our bodies to fight off.  They are completely different organisms that invade in completely different ways.  A bacterial infection is a growth of harmful bacteria in the body.  You may have heard of E. Coli or Streptococcus bacteria.  We have developed antibiotics to help us fight these bacterial growths.  Penicillin (from fruit mold) was the first antibiotic developed and scientists are constantly creating new antibiotics to keep up with resistant strains of bacteria.  Resistant strains have evolved to survive our antibiotics and require new, typically more powerful antibiotics to kill.

Our immune system is the main line of defense against viruses.  Antibiotics only work for bacterial infections and have no impact on viral infection.  Scientists have created a new class of drug called antiviral drugs.  These drugs help suppress viral development.  You probably have heard antivirals are used to treat HIV.  Common viral colds and infections have no drug treatment, though, and you will need to wait for your body to fight the infection.  

When your body fights an infection, it builds up immunity against that specific strain for future attacks.  (Unfortunately, the body cannot build up immunity against bacterial infections.)  Building up immunity means that your body will remember a specific virus and kill it before it does harm.  When we get a vaccination, we take a weakened or ‘dead’ form of the virus into our body.  By doing this, we trick our body into thinking that it already fought this type of virus and we are able to build immunity BEFORE actually catching whatever strain of the virus we are vaccinated against.

Hope this helps!
