Answer:
1. hepatitis; 2. tetanus; 3. influenza; 4. polio; 5. colds; 6. pertussis
Step-by-step explanation:
Hepatitis: Liver inflammation, regardless of the cause, is called hepatitis. The best known are viral hepatitis A, B, C and D, but, in addition to other viral forms, some hepatitis can be bacterial, caused by disorders of immunity or metabolism, or even by toxic substances. Vaccines (prevention by immunization) is part of actions to prevent only hepatitis A and B
.
Tetanus: It is a serious, non-contagious infectious disease caused by the toxin produced by the bacterium Clostridium tetani. In the form of spores, this bacterium is found in animal and human feces, on land, on plants, and on objects, and can contaminate people who have skin lesions (wounds, scratches, cuts, animal bites, etc.), which the microorganism can penetrate.
Influenza: Acute viral infection of the respiratory system, of high transmissibility and global distribution. An individual may contract it several times over a lifetime. In general, it has a self-limiting evolution but may present itself with a severe form. As the virus of Influenza is always mutating, it's necessary to have the immunization every year.
Polio (childhood paralysis): is an acute contagious disease caused by viruses that can infect children and adults and in severe cases can lead to paralysis in the lower limbs. Vaccination is the only form of prevention. All children under the age of five must be vaccinated. This disease is already eradicated in several countries.
Colds: The common cold is a benign viral infection of the upper respiratory tract that mainly affects the nose and throat. There's no immunization for this type of infection.
Pertussis: known as whooping cough, is a highly contagious disease caused by Bordetella pertussis bacteria. The symptoms are related to respiratory tract infection, with paroxysmal or spasmodic cough
