Description:This transmission electron microscopic (TEM) image reveals some of the ultrastructural morphology exhibited by two Adenovirus-2 virions. The sample had been pelleted, thereby, concentrating the viral particles prior to viewing under the microscope. Visible at this high magnification are the capsomeress, which in this case were hexagonally-shaped, also called hexons, and which together comprised the outer covering of the adenovirus known as a capsid. These adenoviruses displayed an icosahedral symmetry, which means that the shape was characterized by 12 vertices, and 20 facets. Each virion was 70nm – 80nm, and exhibited no spikes.
Adenoviruses are very common and come in many types. Depending on the virus type, adenoviruses can cause:

- respiratory (breathing) problems that can include cough, fever, and runny nose

- headache

- sore throat

- eye infections

These symptoms can last up to 10 days.

Infection with adenovirus can also rarely lead to more serious problems, such as pneumonia, stomach and bowel problems, and even death. Some people who are infected may have to be hospitalized.

Adenovirus infection can be spread from person to person through the air (for example, by sneezing or coughing). It can also be spread by personal contact, such as touching an infected person or handling objects that an infected person has touched.
