What is viral hemorrhagic fever.

       

                                                                                                                                                                                                                              All right so we're going to talk about viral hemorrhagic fever. I'll try to go through most of the topics we need to know under this setting so basically what I wanna do is or achieve is to tell you something about all of them and try to be very precise regarding most of them with some of them with more material to know and some of them just to let you know what they are where they are and how do they present so pretty much name tells the story viral hemorrhagic fever so, I'd say of course viral this is a febrile illness and it gives you hemorrhages so that's pretty much it is and it is a multi-system disease the viruses which they cause it all of them are RNA and we lived in a fatty layer and pretty much humans are not the actual host after those viruses humans are accidental hosts the whole sauce actually the other roden mosquitoes or ticks so somebody some other animals are the actual hosts and humans are pretty much not the actual hosts but end up getting it and getting infections so if we know but the you know those actual holes rodents or mosquitoes or ticks we can pretty much locate them in different geographic areas and then can you know delineate which areas that specific illness is found so that's another character of these diseases so the diseases where the actual host is so if you we know where the hostess we can tell where the disease is so five families so we will try to go through most of the viruses listed and I have a disclaimer to made most of it after information is from the CDC some from Mandel that's pretty much the sources so CDC was the main source of all the information actually and pictures are also actually from CDC a very few which are not from CDC okay Arina Verdi is the first group so this group actually all of them before we go to know which which are which they are but basically the actual horse is the road dance so anybody can tell what is the difference between these two which one is the rat and which randomize that smaller is Mouse and the bigger is red that's what I found out during the process of working out so yeah Arina virus is usually rodents which are rats mouse sometimes squirrels but the rats are the notorious month so they actually are the actual reservoir for this these diseases they can infect themselves that's one way and they keep on carrying the disease the other ways they can trance or very early you know the th transmission happens through the ovarian transmission to the key to the kids that's how the carrier then humans coming to contact with them through excreta ingestion mucus membrane skin breach and some other ways to do it and that's how people get infected human human transmission Brer but it does happen. So we'll talk more about that but yeah that's the main or you know arena viruses they are in the rats or rodents and they remain that's their host and they get transmitted to human by a contact of their excreta or themselves and that's how people get infected really you can transmit to other humans so this is the list of the viruses from CBC actually so lymphocytic or you meningitis virus years of discovery so that's the pretty much oldest one at the list and we all know this virus in the context of transplant host who gets a meningitis and that's usually lymphocytic Corie meningitis virus other viruses here I'm gonna talk about is less hours and lose your hemorrhagic fever basically you have viruses and the names just out the story - the location where those viruses are found Argentine hemorrhagic fever believing in Lhasa so that's pretty much the family is so I'm gonna talk live very briefly about some of them and go on to the next family of viruses so the first one is the lymphocytic career meningitis virus so if you look at the name it has a chorion in it so that just tells you it just causes meningitis and it has fatal implications the murders can't transmit it to fetuses the humans get meningitis with it and they can you know mother's contrasted it to babies so test hole problem with this virus so transmission is from rodent Explorer person-to-person does not happen but as you told I told you earlier vertical transmission from mother to fetus is to occur and rarely transplantation that's the classical case for in the board review this virus they present a case where this is the answer signs and symptoms the basic illness first phase is usually all of them pretty much gives you the same symptoms so really hard to say which month - you know just based once symptoms specify which virus it is fever muscle aches headaches poor appetite nausea vomiting sounds like a flu-like illness right actually so when that fish gets over.....
