A mosquito bites a person who subsequently develops a fever and abdominal rash. What type of transmission would this be? a. mechanical vector transmission b. biological vector transmission c. direct contact transmission d. vehicle transmission

Which of these are true of active acute infections in animals. So we have one is a productive infection to you get long lasting immunity from IT three. The results of integration Of viral nuclear acid into the host. four, followed by chronic infections. Five leads to tumor formation. Okay, so these are five statements. Which of the Medford Is it going to be a one and 2, B two and 3 C3 and four D four and 5 41 and five. So an acute infection. So this is over a short time frame. So what can we say about such an infection? First of all, everything's happening pretty fast. You're probably not going to get slower processes like integration or to information those are hallmarks of chronic persistent infections, so it's probably not going to involve three or five. Would they be followed by chronic? Typically not. Typically if you if you have a virus, it's either predisposed to acute or predisposed to chronic. There are some that ends up doing both depending on the situation, but an acute infection is not usually followed by chronic chronic infection. So what we have left wealth of a productive yes, you do have uh production of viral particles going on because in acute infection is brief and intense, lots of variants and having lots of various means. You do tend to get long lasting immunity, plenty of anticipation for the host immune system to work with, and you'll probably get antibodies being produced. So the answer is going to be one and two, which means the answer is a.

The most common way that humans can inquire that can acquire infectious disease is through a contaminated water. The mosquito bites si sick animals, the infected humans. But the most common way. While all of these are possible, the most common way is actually through contaminated water contaminated water. So, um, thanks for watching. And I hope this helped.

We will be discussing about how the HIV is transmitted in humans through HIV stands for human immunodeficiency virus. It's a type of retroviruses in which the the genome is enclosed within the protein code the genome in HIV is RNA. Now it is the positive organisms of for two acquired immunodeficiency syndrome. Now there are 30, there are four modes of transmission for HIV. The first is having sexual contact with infected person. Now the HIV will only be transmitted if further sexual even individual have unprotected sexual contact with the infected person. This happens you to the include do the contact before fluids. The next mode of HIV transmission is transfusion of blood. Yeah, if the blood of an infected person is transfused into a into a healthy person, then the HIV will also pass through it to the healthy individuals. Another motive sharing of infected needle then see it injured. It is very important to ensure that you are always using a new and unused Syrian when getting injected or anywhere or the mostly this happens in tattoo shops where the people go to get the body tattoos, they sometimes what they do is they do not change their needles and this is one of the major mode of transmitting HIV, another way through which HIV can be transmitted is through an infected mother too. Oh, Peter's or work child by a Pleasanter Now, since placenta carries all the, the placenta is the carrier of nutrition and everything to the child or the embryo, then uh, if the mother is infected with HIV, then it will also be transmitted to the on one child. So these are four major types of transmitting modes for HIV.

Butters are usually animals that can carry disease. Different types of pear sides infections inside of them and then go from poster hose, jumping around, flying around, biting them, inserting those parasites disease infections into a host. Usually factors are Arthur Potts. These are mosquitoes, ticks, animals of those sorts that have the ability to go from most of holes, infecting each of them in separate times. Okay, Oh!
