The cylindrical helical virus type is associated with the tobacco mosaic virus. Envelope viruses, such as influenza and HIV come covered in a protective lipid envelope. Most animal viruses are classified as icosahedral and are nearly spherical in shape. The viruses within these categories share similar characteristics.
Viruses are also the most abundant biological form of life on the planet. The first thing a virion does is enter a cell and becomes a virus. Next, it reproduces, creating viral protein and genetic material instead of the usual cellular products. A virus can then spread through a wide variety of means, such as touching, coughing and sneezing.
The body fights viruses by breaking down the viral genetic material via RNA interference. The immune system then produces antibodies that bind to viruses to make them noninfectious.
Lastly, T cells are sent to destroy the virus. Antiviral drugs can treat viruses by inhibiting viral development and slowing down disease progression. These drugs help fight the flue, chickenpox and forms of hepatitis. Vaccines create a herd immunity that helps prevent an outbreak. There are five different types of viruses: Conjugate vaccines, inactivated vaccines, live, attenuated vaccines, subunit vaccines and toxoid vaccines.
There are several ways people can slow the spread of a virus in lieu of drugs or vaccination. These include thorough and frequent hand washing, eating a fruit and vegetable-rich diet, using an alcohol-based sanitizer and getting enough sleep each night.
Around the world, nurses contribute to the prevention, management and containment of viral outbreaks by caring for infected patients and educating the public on prevention strategies. Advanced practice nurses also fill a leadership role that involves working with government leaders and advocating for health care equality.
