What Is a Virus?	2014-07-22		.txt	text/plain	4769	260	60	Studies of viral replication indicate that most viruses self-assemble as a result of interactions between the viral proteins to form a viral capsid that interacts with the nucleic acid to form the whole. The viral proteins are produced in one part of the cell, the replicated nucleic acid in another, and somehow they find each other, interact, and form virus particles that are expelled from the cell. Indirect contact spread includes cases where mucus from a runny nose may get onto the hands, or virus may be left on a surface such as a doorknob, telephone, or countertops, and is picked up by a second individual, who then touches his eyes or nose, resulting in infection. Vector transmission is a very common means of transmission; the best studied cases include yellow fever, dengue virus, and West Nile fever-viruses all transmitted by mosquitoes. As many as 400 million people are infected annually by dengue virus, which is caused by any one of four related viruses transmitted by mosquitoes.	./cache/cord-018164-h5k1zsyg.txt	./txt/cord-018164-h5k1zsyg.txt
