The Nipah Virus causes severe illness. A person with this infection will get a respiratory disease, a term that includes extreme conditions affecting the organs and tissues that make gaseous exchange possible in organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, alveoli, pleura and the nerves and muscles of breathing.

The researchers discussed in class and all agreed that Zika Virus is a very dangerous and continuing to plaque southwest Florida. In hopes to promote public safety and aware other about the virus and how it can be contracted, the researchers decided to focus our intervention towards first year students living on campus. The researchers started off the project by contacting Florida Gulf Coast University Student housing and Residence life. The plans for a Zika Virus intervention were shared with the administrator of Eagle Hall in South Lake Village which is an on campus, first year housing for students who attend the university. On September 20th the researchers sat down as a group to discuss a game plan of how an intervention would be arrange…
Of course, this means that the West Nile Virus is elusive and rare. Not only that, the rarer a disease, the harder it is to diagnose it. Which means, this virus is deadlier than the common disease. The West Nile Virus is deadly. Face it.…
West Nile virus caused a huge outbreak in 2013 ;this is called a mass hysteria. Mass hysteria is when people think of imaginary or real threats from rumors and lies. West Nile virus causes fever,headaches,body aches and skin rash. The virus is spread by mosquitos which makes it more likely to get infected. People were constantly worried that they or their children will get the virus . This goes along with The Crucible because several people started talking about witchcraft and then it began to spread.The more people spoke of it ,the more they were terrified. The West Nile virus only started because one person overreacted. The Salem Witch Trials happened because one parent overreacted.John Proctor dies because of Abigail,Elizabeth and society.What was the main reasons for John proctor's…
The West Nile Virus is transmitted to humans and animals trough the bit of an infected mosquito. The mosquito's biological name is Flavivirus. Not that many people get sick from West Nile Virus but there are still people that end up in the hospital. To treat West Nile you usually have to go to the hospital. To confirm that a person has West Nile Virus a blood sample has to get tested. People can help prevent West Nile by doing simple things around the yard.…
Viruses are non-cellular obligate intracellular parasites, requiring a living host cell in order to reproduce. A developed viral particle (virion) lacks the metabolic machinery of cells, containing just a single type of nucleic acid (DNA or RNA) encased in a protein coat or capsid. Viruses can be distinguished by their structure and by the nature of their genetic material (single or double stranded DNA or RNA). Viruses that affect humans are more difficult to study because they require living animals, embryos, or cell cultures in order to replicate. The particular host range of a virus is determined by the virus’s requirements for attaching to the host cell and the availability, within the host, of the cellular factors needed for viral multiplication. In some viruses, the capsid is covered by an envelope, which protects the virus from the host’s nuclease enzymes. Spikes on the envelope provide a binding site for attachment to the host. Influenza virus is an enveloped virus with many glycoprotein spikes. Viruses are larger than prions and many times smaller than bacteria. They range in size from 30 to 300 nm.…
Viruses are DNA wrapped in a thin coat of protein that replicates only within the living hosts.…
The yellow fever virus is a dormant, single strand of RNA, packaged in a lipoprotein envelope. The transmissions occur through bites of infected aedes aegypti or haemagogus mosquitoes. Human and nonhuman primates are the main reservoirs of the virus. Traveling through a lytic life cycle, the virus first enters the host and is phagocytosed by a macrophage. The virus then sheds its envelope to keep from being further digested. The macrophage continues with the virus to the lymph nodes where the virus begins its replication. The virus leaves the host macrophage and then goes out to infect others. As the lymph nodes carry the virus through the bloodstream, it enters the liver. Inside the liver, it infects the Kupffer cells that line the blood vessels. The cells are macrophages that are needed to clean cellular debris and…
Viruses are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human.…
Equine encephalitis is a virus us humans in south texas are exposed to through the abundance of a common vector, mosquitos. Mosquitos are known to be the most obligatory biological vector for transmitting these viruses. Of the three different types of “Group A” arboviruses, the eastern equine encephalitis and western equine encephalitis are the ones native to our area and can also cause febrile disease in humans and horses. EEV also utilizes hosts in two different way. One being a reservoir host (wild birds, rodents) and the other is a “dead end” host(horses, humans). The clinical disease occurs when the virus begins to replicate on site of the bite and the proceeds to enter the blood stream and begins attacking the central nervous system. While cases in humans and horses are rare, it is important especially in our region where the vectors are active, to know the method of transmission, common vectors and hosts, as well as the maintenance and spread of the EEEV and WEEEV.…

The cycle is completed when the virus approaches the central nervous system by the diffusion through neurons. since the environment is the best for the virus, it begins protein synthesis and RNA duplication. First, the RNA strand has to be duplicated to make a new generation of the virus. At the same time the proteins which are required to make the new virus copies are synthesized. The virus’s synthesized proteins and the new RNA strands assemble and form the new generation viruses which may leave the host cell through a budding process, forming an envelop from the host cell membrane. Eventually the copies can affect another host or affect the brain causing an abnormal behavior2.…

Many people have encountered a mosquito bite and the side effects that come with being bitten. However, many people do not know about the deadly virus that mosquito’s may carry. The West Nile virus can cause other illnesses known as West Nile fever and West Nile neuroinvasive disease. West Nile virus first came to the United States from Africa. It was initially found in a Ugandan woman in 1937. Sixty-two years later it was detected all over the states in exotic birds in zoo’s, from the death of many crows, and in other animals. All viruses need a host to live off of, this includes West Nile virus. West Nile Virus was originally, and still is, spread between mosquitos and birds. Since birds migrate all around the country, the West Nile virus was easily spread.…
