Viruses that persist in the (host) cell and cause recurrent disease are called latent. True or false?
Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions?
"This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too."
Group of answer choices
a. Measles
b. Parvovirus
c. Coxsackie virus A
d. Rhinovirus
A common characteristic of viruses is that they contain both RNA and DNA in their genome.
True
False
