Poliovirus

Poliovirus is a member of a small group of RNA viruses that cause polio in humans. This entire group is part of the picornavirus group.

Poliovirus belongs to the picornavirus family. These are RNA viruses that do not have an outer shell. Their genome is represented by single-stranded positive RNA.

Poliovirus infects nerve cells and can cause the development of poliomyelitis, an infectious disease characterized by predominant damage to the gray matter of the spinal cord and brain. This leads to the development of paralysis and muscle atrophy.

The main source of infection is a sick person or a virus carrier. Transmission occurs through the fecal-oral route through contact with household items, food and water contaminated with the virus.

Prevention of polio includes sanitary measures and vaccination. Currently, effective live oral vaccines have been developed to control the incidence of the disease.

Poliovirus, or poliovirus, is a member of a small group of RNA viruses that cause the disease known as polio in humans. Poliovirus belongs to the picornavirus family, which also includes other important viruses such as hepatitis A virus and rhinovirus, which causes the common cold.

Poliomyelitis is an infectious disease that primarily affects the human nervous system. The virus is transmitted through the fecal-oral route, most often through contaminated food and water. After entering the body, the virus multiplies in the intestines and then spreads through the blood, infecting nerve cells.

Most people infected with poliovirus do not show any symptoms and go undetected. However, some people may experience a mild flu-like illness, which includes symptoms such as fever, sore throat, headache and vomiting. In rare cases, polio can progress and cause paralysis, which may be temporary or permanent, depending on the severity of the disease.

In the past, polio was a widespread disease, causing serious consequences such as loss of motor function and disability. However, thanks to global vaccination efforts since the 1950s, the incidence of polio has decreased significantly. Currently, polio remains endemic only in a few countries.

The polio vaccine, developed by Jonas Salk, was introduced in 1955 and became one of the most successful vaccines in medical history. It is based on weakened or killed polio viruses, which stimulate the body's immune system to produce antibodies that protect against infection. Large-scale vaccination campaigns have significantly reduced the number of polio cases, and efforts are now underway to eradicate the disease.

In conclusion, Poliovirus, or poliovirus, is a member of a small group of RNA viruses that cause polio in humans. However, thanks to effective vaccines and global vaccination efforts, the incidence of polio has decreased significantly. Vaccination remains a key tool in the fight against this virus, and efforts to eradicate polio continue around the world.

Poliomyelitis virus is a member of the picoplasmoid group, which are members of the RNA family II. This group also includes members such as enteroviruses (for example, Coxsackievirus in young children), Epstein-Barr viruses and cytomegaloviruses, as well as pathogens such as coronaviruses and reoviruses. All of these viruses are RNA carriers.
