Organism and viruses: confrontation.

 When are first viruses displayed on Earth, a science never say, and they are neighbouring with human since his birth, and this is never stopping. Today are a few 1000 viruses, causing infections and everyday scientists opening are new. And importance to know about theirs a much ,as to protect care, when a famous Russian doctor and scientist Pirogov said, that A future is belongs to medicine preventing.

Viruses are microscopic form of life, which need for organism in human or animal, and a most often these are pathogenic agents, and a becoming reason for hard infections as Hepatitis C, poliomyelitis, AIDS, Rabies. Entering virus into cell defining importance hardeners for cure is a hard to remove a disease, keeping a cell. And thus effective antivirus remedies are less, and they are enough specifically. Pathogenic microorganism are faster adopting and staying not perceiving/mutating/ to the new entering in virus ology sphere , microbiology and immunology. And a few base ways for transferring  virus infection:

Aero gene or by air-dropsy as ARVD, flu, measle, chickenpox, and other.

Alimentary or by fecal-oral are hepatitis A,E, polymielitis.

Hematogenic through blood are hepatitis B,C,D, AIDS, RABIES.

Transmission through insects bites as encephalitis, mosquito fever and etc.

Vertical virus transferring from a mother till baby is on the pregnancy time, births, as flu, rubella.

Sex through AIDS, herpes, papilloma, hepatitis B.

Not an all viruses causes a disease, and they are lead an own host in a carrier regime, without symptoms, and in raw cases a host is staying for source an infestation.

Any foreign substance is antigen, entering in organism always meeting with cells for immune system, and in immunity is specifical, good as inborn, or manufactured antigens will be destroyed till development symptoms a disease , thus he is not to sick, and not carrier for infection.

Respiratory diseases for top breath ways are viruses contagious us a different cold within all our life, and immune system is training and creating protection on a case for emergency situation in a displaying new pathogen.

And a how a most microorganisms viruses for flu circulates around us every year, thus you can to sick on the summer, and on winter a chance is higher, that peoples stating in closed, bad ventilated places. Cold air lowering a natural resistanc3 for infections nose ways and virus is surviving. 

A one protection is against infection is specific preventing is vaccination, which helping for immune system manufacturing antibodies as proteins molecules, which are fighting with infection agents. And in our generation as adult, a having mark on pre shoulder  is a vaccination result against black natural smallpox. And thanks for these vaccinations a disease  fought in all world , on 1980 a needing for vaccination is stopped.  And a few children s infections are entered in national calendar for vaccinations and without a serious contraindication you not need to avoid vaccinations, thus children here in risk and his surrounding. And in infections, attacks at kindergartens or schools is adding quarantine.

And on flue epidemic, WHO IS showing booklet with prognosis, by a which manufactures for vaccines forming her structure. And advising doing vaccination who entering in risk and for complications displaying as pneumonia, breath failure, adults, children's , chronic cardiovascular diseases, diabetes are lowering ability for organism resistance to infection, obesity, as in limiting mobility for lungs and a rising for probability of congestive appearances. But vaccination a not always ability to protect from infection, but preventing a hard disease course and dead of her. But why is not vaccinating against every ARVD , THAT are 200 kinds of viruses causing , thus and manufacturing vaccines against every is a not need, that a such quantity for vaccinations will not benefit for organism, thus vaccination against a most dangerous.
