Video transcript

okay so it's going to become more apparent I'm sure as you hear my voice in this video but I do not feel well and I'll tell you but particularly I guess why I don't feel well so this is me and I'm drawing kind of myself I've got some red hair and I'm also going to draw in my throat and cut on my nasal passages so here's my throat coming back down and it connects with my nasal passages in the back of my throat so I've got those structures kind of drawn in here for you and I'll tell you that part of the reason I don't feel well is because I have a really sore throat feels like it's on fire to be honest right now so kind of right in back here at the back of my throat it's really sore I'm also probably you can tell by the sound of my voice and how nasally it is I'm pretty congested so kind of right up here in my nose I'm pretty congested and believe it or not right now as I'm making this video I have a fever I have a 101 101 point eighth degree fever and that's in Fahrenheit so that's actually about a thirty eight point eight degrees Celsius fever and the reason I have all of these terrible symptoms excuse me is because I have an upper respiratory infection so let me write that in for us upper respiratory respiratory infection infection or sometimes this is shortened to URI you are I and so that's what I want to talk about I want to talk about upper respiratory infection so let's start by thinking about what an infection is well an infection let me get the right pen is is a disease-causing agent so an infection is a disease-causing agent that's going to come in and it's going to invade our host tissue so in in me my cells it's going to invade those cells and it's going to cause a reaction and in the case of upper respiratory infections those disease-causing agents are typically either going to be bacteria so let me come and draw some bacteria in here I'll draw like a little chain cut out of bacteria or or viruses so this would be a virus this is kind of a classic little cartoon of a virus so these are the disease-causing agents so that's the infection part what about the upper respiratory this is actually a pretty nonspecific term here because there's a lot of parts of our upper respiratory tract bullets let's just go through them they kind of make intuitive sense so our respiratory tract is the the tract that we're going to breathe through so let's let's think about where the air that's going to go eventually down into our lungs here where that air starts so it's going to start at our nose we breathe into our nose sometimes and right here we have excuse me our nasal cavity and if that becomes infected by something we have rhinitis so why rhinitis yeah right kind of up here and you might be able to remember this if you think of rhinoceroses rhinos that have excuse me a big horn on their nose so we've got rhinitis in our nasal cavity and then kind of where at the back of our throat is where your uvula that little thing that hangs in the back of your throat that area is called the pharynx so if that becomes infected in this area we have pharyngitis so fair fair in gitis and then as we continue to go down the the respiratory tract underneath the the pharynx we actually have a little flap that covers or that sari protects the airway in the back come in the bottom back of our throat it protects our airway or our our esophagus respectively when we're either swallowing food or breathing in air and that little flat kind of down and the bottom back of our throat is called our epic lie yes and if that becomes infected we can get epiglottitis so epiglottitis and so as we continue to go down beneath the epiglottis we have an area called the larynx and that's where our vocal cords our voice box sit so if that becomes infected we could get laryngitis so we're in laryngitis and then not typically talked about with the upper respiratory tract usually that's kind of where we end the upper respiratory tract and start talking about the lower respiratory tract but in the case of upper respiratory infection sometimes included is the top part of the trachea which is going to eventually kind of split off to the lungs so if that becomes infected we can get we can get tracheitis so trach tracheitis right there now you might have picked up as I've gone down this list that all of these in in itis so you see rhinitis pharyngitis itis itis itis itis itis well I this is actually a suffix that's often used in a description of inflammation when something becomes inflamed and that's what's happening that's what's causing some of these symptoms as this as these little disease-causing agents invade my cells they cause damage and that causes a response like I told you in our body and that's the inflammation so that's where all of these ideas are coming from so most commonly these disease-causing agents are a virus that's that's kind of the majority of upper respiratory infections and of those viruses which are already the majority the majority of viruses are going to be Rhino virus and that's so common that Rhino virus is also called the common cold so when you think of the common cold and how crummy you feel you have Rhino virus probably and you can imagine that with the same kind of route that that Rhino route that this virus loves to hang out in your nose and kind of your nasal cavity and cause a head cold that'd be the common cold another type of virus though that might cause an upper rest taury infection a little bit less common but still prevalent would be the influenza virus you hear a lot about that influenza this is another virus that can cause an upper respiratory infection and then aside from these there are viruses like the corona virus corona that adenovirus and really there are there are more than 200 different viruses that can cause an upper respiratory infection and that's kind of the majority of the the disease-causing agents but we also do have bacteria that can be the culprit and probably the most common of those is streptococcus I'm going to shorten that to strep streptococcus it's a line of these little [ __ ] eye is spherical kind of ball shaped bacteria and there are a few different forms of streptococcus there's strep a the strep see the strategy that can all cause at an infection in the upper respiratory tract but probably the most common of these is strep a and I'm particularly loathsome of strep a because that's what's currently causing my upper respiratory infection so you can imagine probably a ton of these little strip a bugs hanging out in my body as I'm speaking to you and I mentioned to you that that my current upper respiratory infection is causing me some symptoms and really you can you can think that these symptoms are a direct result of the infection and subsequent inflammation caused by these little bugs so some symptoms I mentioned I mentioned some of the most common ones because I'm currently experiencing them but you're going to have things like runny or stuffy nose so runny or stuffy so or congested I would be a little bit more appropriate word so it's either kind of we've got some nasal leakage that'd be leakage kind of that runny coming out of the nose nasal leakage or some nasal congestion that stuffy nose but that's a pretty and symptom what's happening with that is that your body as part of that inflammatory response is trying to clear these disease-causing agents out of your body and so it's going to produce more mucus to try to trap these things and then eventually expel them and as it as this mucus accumulates it can congest and cause that stuffy nose but eventually it's going to kind of drain out and it's either going to cause so you're going to leak down the back of your throat here so let me kind of draw some mucus if my mucus kind of traveling down the back of your throat from your nasal cavity and irritating your throat even more or it's going to come Kani out of your nose and that would be the runny side of these symptoms and then you're also going to have like I said that sore throat so sore throat and as these dizzy or as these little agents invade these cells they kill these cells these bacteria will you know jump inside these cells and so all these viruses are going to destroy these cells so it actually is hurting our body and that's part of that soreness that we're feeling so we might have a sore throat and another kind of big hallmark sign of the inflammatory response to infection is a fever a fever and again I really did just check my temperature and it was a hundred and one point eight so I'm not feeling super super well now if you had to guess how I came about this particular strep a infection what might you what might you guess as a reason why do you think I got strep a into my upper respiratory tract so it could infect it well I'll tell you that one thing I do and you do probably a whole lot is I touch with my hand my nose in my mouth so all the time I'm touching my nose I don't ever pick my nose I've never ever done that before ever but I do touch my nose I touch my mouth frequently all the time throughout the day and I also touch a lot of other things I touch doors I touch objects around the room I touch other people and I probably got a handy amount of these germs on my hand and put them right on the entrance to my upper respiratory tract so I put them right on mine ears that's the the nostrils and right on my mouth which opens into kind of my oral cavity here and so that's one of the most common ways that you can get these infections another way is say I were to sneeze maybe I were to sneeze or I were to cough I'm expelling a lot now of these kind of infected little parts all throughout the air so people that are around me these particles might land on them land on their hands or land on their on their face and they might become infected and so these are kind of big ways that upper respiratory infections are transmitted with hand to hand contacted kind of through the air but really both of these are are really really heavily preventable so with hand hand contact if I wash my hands a whole lot so hand washing hand washing I can try to get some of these germs off my hands a before I touch my mouth and be before I touch other people which is going to prevent a lot of this transmission also when I when I do call for what I do have to sneeze I can be really polite and I can cover that maybe with my shoulder so I'm going to cover cough excuse me cough and sneeze I'm going to try to prevent those particles from flying throughout the air and then lastly some of these infections like the influenza virus there are actually vaccines again so that's why we get flu shots and that can prevent me from getting it and also from you know potentially spread it if spreading it if I were to get it but to be honest preventing these illnesses is not what I'm most worried about right now because I already have my upper respiratory infection now I'm worried about treatment how do I feel better so let me write treatment down for us and I'll tell you that really with a lot of these since again the majority are caused by viruses there isn't a specific treatment to kill these viruses we kind of have to let our body's immune system identify and start to kind of at back against these and we kind of have to wait it out so a lot of the treatment is going to be really supported one of the things we can do is we can hydrate we can drink lots of lots of clear fluids like water hydrate and a hydration is going to do two things for us one it's going to replete it's going to replace a lot of the fluids that we've probably lost one of the things our body is trying to do is it's trying to get rid of these infections so we might be trying to urinate more just so we can eliminate as much of these infections as possible so I'm going to replace some of the fluids that I've already lost hydrating also is going to help me thin at some of this mucus that's produced in order to kind of trap and expel the bacteria which is going to change this stuffy nose into more of a runny nose I can also kind of try to relieve the symptoms so with treatment I'm going to put in symptom relief so I can do things like stuck on a lozenge that might have a have a little bit of menthol in it or something that's going to make my throat feel better I might use an over-the-counter nasal decongestant so I've got a congested nose and I might decongest it to allow some of that and you just flow out if I have a fever like I do right now and I actually did this symptom relief I took some Tylenol you can get over-the-counter Tylenol or ibuprofen something that has some antipyretic that's really I'll write that up here anti-pirate ik that's kind of a fancy word for fever Buster antipyretic so a medicine that has an antipyretic quality to it like Tylenol err or on or at ibuprofen and I'm going to try to get a lot of rest I'm going to get a lot of rest because I don't want my body to have to expend any more energy than it has to on peripheral things like running around the block or lifting a bunch of weights so that it can divert that energy into fighting off this infection with me now that's for these these viral infections that there's not a real cure for bacterial infections we could use antibiotics and again these aren't very common upper respiratory infections the majority of these upper respiratory infections are caused by viruses so antibiotics are going to do anything for those but if it is caused by bacteria like strep a we could use some antibiotics which our doctor will give us when we go see him
