Worst sites to get a viruses

Let us take a look at the 10 worst computer viruses of all time. Melissa was actually created back in by David Smith. He designed this using a macro in Microsoft Word. The virus itself would be spread through email messages that were sent from one user to another.

He actually named the virus after an exotic dancer that he new from Florida. The virus worked by tempting those who received the message to open a document that they have asked for. It even states that you are not to show it to anyone else. It would end up clogging entire emails systems because of how many emails were being sent out. Smith ended up being convicted after a long trial and received 20 months in prison. This virus actually hit the Internet about a year after Melissa did. It came from the country of the Philippines.

This threat actually came because of. It was a program that could stand on its own and was able to replicate itself. The I Love You virus actually made it4s way through the Internet via email.

It was inside a message that appeared to be a love letter from another person. There would be an attachment to the email. If you were to open that, you would be infected.

This would create a host of problems, such as being copied several times and hiding on the hard drive. It would replace certain files with copies of the virus. The problems just kept coming.

With this virus, a new bar was reached. Deseret News homepage. Filed under: Coronavirus U. The omicron variant symptoms you should worry about.

There is no vaccine available to prevent this disease, according to the NHS. The best way to reduce the chances of infection is to wash hands regularly, avoid contact with camels and not consume products containing raw animal milk. Live Science. See all comments Don't said:. Meh said:.

Comment on rabies fatality rate. Although all warm-blooded animals are thought to be susceptible to rabies, there are strains of the rabies virus multiple bat stains strains are maintained in particular reservoir host s , with some cross over especially in the US between raccoons and skunks.

Although a strain can cause rabies in other species, the virus usually dies out during serial passage in species to which it is not adapted, and non-carnivores cows, horses, deer, groundhogs, beavers AND CATS, like small rodents, are dead-end hosts. The CDC estimates in the US, 1 million dollars per potential life saved is spent by post-exposure prophylaxis in cases of exposure to animals other than bats, canines, fox, raccoon, skunks. Hundreds of unvaccinated cats are infected with, and die or are euthanized of rabies each year -no way every human exposure to "the kitten in the park " is tracked down.

Certainly, many farmers and ranchers are unknowingly exposed. Yet almost all of the people diagnosed in the US yearly, knew they were bitten by a dog when outside the US or handled a bat. And there have been several incidences since , where people got rabies secondary to solid organ transplants.

Species vary in susceptibility to various strains, humans are 'most' susceptible to canine rabies and, in the US, the silver-haired bat strain. This is a solitary bat with infrequent human interaction, whereas we have much more exposure to big and little brown bats and Mexican free-tailed bats.

Only a small percentage of any of these have rabies, -it kills them too! The virus needs to get to a nerve, so if a bite is not deep enough, or a small viral load is deposited, or the 'victim' immune system responds - an infection will never be established. If the virus is able to get to a nerve, it attempts to travel up an axon, to the brain- again, the immune system may eliminate. As rabies is a slow virus, it can self -immunize, explaining the presence of rabies neutralizing antibodies in Amazonian Indians and others who have never been vaccinated?

The reason why a mature dog is considered immunized 28 days after its first rabies vaccination, is if it has been exposed or is 'incubating' rabies virus but the virus is more than 28 days away the vaccine will prevent infection. Although antiglobulin is given, PEP - a killed vaccine, is basically, rapid immunization. It also is more likely than other variants to be asymptomatic; rather than lying in bed, infected people tend to feel fine or only slightly ill, and spread it.

In its early days, this strategy worked for the virus, and it ran rampant. In most parts of the world, the majority of the population has been infected or had some form of vaccination, and has some immunity. In the U. By mid-February, omicron will recede. To be sure, widespread vaccination slows the rate of mutation, reducing the risk of emerging variants, experts noted.

Stanley Perlman, professor of microbiology and immunology at the University of Iowa. But over time, there could be gradual evolutionary change, through a slow accumulation of mutations. Or change could happen suddenly, as we saw in omicron.
