Flu Symptoms and Diagnosis
Female Voiceover: At this point in your life, you've probably been infected with the influenza virus.발음듣기
All the symptoms that we feel when we're sick with the flu are related to the course that the virus takes as it moves through our body.발음듣기
Let's say that someone who is infected with the flu sneezes or coughs near you and they spray a bunch of tiny droplets into the air.발음듣기
Another way we can get infected is, let's say some of these droplets settle on a surface like a table for instance.발음듣기
So if we're unfortunate enough to touch a surface like this and then touch our mouth or our nose we can get infected this way as well.발음듣기
This is why practicing good hand hygiene is so critical in preventing the spread of disease.발음듣기
The damage that these cells experience is going to show up as the symptoms that we're so familiar with.발음듣기
In response to the damage that the virus causes the body, the immune system is going to increase the temperature of the body in hopes that this will make viral replication more difficult.발음듣기
This battle that the body is fighting against, the influenza virus, consumes a lot of energy.발음듣기
So how do we know that it's actually the influenza virus specifically that is making us feel so sick?발음듣기
Typically a person infected with influenza virus will have a fever of over 100 degrees, along with either a sore throat or a cough.발음듣기
During flu season between December and February, doctors who see an influenza-like illness will usually attribute this to an infection with the influenza virus without getting a laboratory test.발음듣기
Because that is what you really need for the clinical diagnosis of an influenza-like illness.발음듣기
Let's think about the places that you'd most likely find an influenza virus in someone who is sick.발음듣기
Remember this is why we have nasal congestion and a sore throat, because the virus is hanging out here.발음듣기
We're going to take this nasopharyngeal swab into the nose, into the back of the throat, to collect some of these cells.발음듣기
We're going to send this to the lab to find out if in fact it's an infection with influenza virus.발음듣기
