1. What is a Virus? A computer virus is a program that can copy itself and infect a computer without the user knowing. Some viruses are made to damage the computer by damaging programs‚ deleting files‚ or reformatting the hard disk. Others are not designed to do any damage‚ but replicate themselves and perhaps make their presence known by displaying text‚ video‚ or audio messages. Even these benign viruses can create problems for the computer. They usually take up computer memory used by other programs

Dengue virus is an epidemic facing many Asian countries. Although the current topic of discussion among health professionals is a possible outbreak of avian flu among humans‚ the dengue virus kills hundreds every year in the same region (ONE). This epidemic is not one that faces easy fixes‚ in fact there is no vaccine for the dengue virus. In this paper I will discuss and explain how the dengue virus poses a great threat to the region and how it plagues the lives of thousands of people in Asia.

COMPUTER VIRUS AND ITS TYPES COMPUTER VIRUS Computer virus is a software program written with malicious intentions. There are number of computer viruses that can impede the functioning of your computer system. DETAIL ABOUT COMPUTER VIRUS They are replicated by themselves. Viruses are so dangerous and malicious that they can be automatically copied and pasted from memory to memory over and over; the transmitting power is too much quick from network to network that can simply hang smoothly running

Ebola Virus The Ebola virus was discovered in the 1976 near the Ebola River in what is now the Democratic Republic of the Congo. The Ebola virus—previously known as Ebola hemorrhagic fever—has been typically a disease of Central Africa‚ which it was until recently. There are five different confirmed strains of the virus. There is the Zaire Ebola‚ the Sudan‚ the Tai Forest‚ Bundibugyo virus‚ each of which can affect humans. The fifth strain‚ the Reston virus‚ has only caused disease in non-human primates

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic

With more than one-third of the world’s population living in areas at risk for infection‚ dengue virus is a leading cause of illness and death in the tropics and subtropics. As many as 400 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus and the most effective protective measures are those that avoid mosquito bites. When infected‚ early recognition and prompt supportive

The Ebola Virus A virus is an ultramicroscopic infectious organism that‚ having no independent metabolic activity‚ can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid‚ either RNA or DNA‚ surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication‚ and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that
