Modern transportation makes it much easier for emerging viruses to travel around the world and infect people. It makes it easier for emerging viruses to travel around the world because with inventions such as planes, if one person has the virus, they are now a carrier for the virus. In a plane, air is recycled, so if the virus is airborne, the virus can potentially infect many people on that plane. Also that plane will land in a different place from where it took off so the carrier would be bringing the virus to a new place. It makes it easier to infect people because with modern transportation like buses and public transit, people are much closer together and easier to infect because of the proximity of each other. These factors attributed by modern transportation give the virus a boost in infecting and spreading.

Modern communication and transportation has affected movement in a significant manner. Movement has become easier and faster due to the various developments in terms of in…frastructure.
They tend to be especially dangerous due to two reasons; first, we lack information about them, such as what causes the disease, and secondly, we lack treatments against t…hem. Because viruses can't be treated with antibiotics, they automatically impose a larger threat. Viruses can be fought with vaccines; however, we don't have these for emerging viruses.
Already existing viruses change DNA. ex: the flu or common cold.
Viral evolution is a subfield of evolutionary biology that is specifically concerned with the evolution of viruses. Many viruses, in particular RNA viruses, have short generat…ion times and relatively high mutation rates (on the order of one point mutation or more per genome per round of replication for RNA viruses). This elevated mutation rate, when combined with natural selection, allows viruses to quickly adapt to changes in their host environment. Viral evolution is an important aspect of the epidemiology of viral diseases such as influenza, HIV, and hepatitis. It also causes problems in the development of successful vaccines and antiviral drugs, as resistant mutations often appear within weeks or months after the beginning of the treatment
Perhaps not the way they are spread but the quantity of people exposed is increased with mass transit of today as well as with travel in crowded airports and other busy transp…ortation hubs.
ireally dont think it affects because in what way or form can it affect right ?
Bacteria and viruses attack the body. Each type of bacteria and virus attack different areas of the body. Also, there are many different ways of gaining access to the body. Th…ey attack the body by trying to shut down a certain system, which without your immune system, would kill you. Bacteria and viruses evolve. However, viruses aren't presently categorized as living organisms.
A virus can be sneaky and mostly the reason why a virus hacks your computer is because they want you to buy their product .About 4 months ago i had a computer virus on my comp…uter called security tool it wanted me to buy there security . Another reason why is because they just want to annoy you or just damage your computer.
One is T.B. and another is the cold, but I don't much about anything else but that.
Because antibiotics are designed to fight bacterial infections, whereas antivirals are used to combat viral infections.
they all have different thingd in them
When you receive a vaccine, it puts a "dead" version of a virus into your body; it is one that cannot reproduce, but instead causes your body to produce anti-bodies that fight… infection. When you come into contact with that virus, you already have anti-bodies to fight the virus in question. In the event that you ALREADY have the virus, do not receive the vaccine. It is not going to properly do its job. So, to give a more direct answer, it doesn't effect reproduction, it simply gives your body a warning that it might show up so that it is prepared.
viruses latch onto a host cell and injects its own DNA into it, this DNA controls the cell and makes it produce more viruses inside the cell, when these are ready the burst ou…t of the host cell killing it, and land on another cell
It starts out affecting everything around the file it comes in, such as disabling, damaging, even deleting files, then it spreads to neighboring files in the process, and even…tually consumes the whole computer to the point where the computer can no longer function.
It adds greenhouse gases such as carbon dioxide to the air causeing global warming.
