I was reading a storybook named "A lost love" by novella English some days ago. There I know how fast Flu can kill, to me I don't really know that it is that a fast killer until I read the novel. Even at times most of us can't identify the differences between flu and a mere cold.
In this post, I will be going deep into it as you know me to be an incoming physiologist. I will be examining just six sub-topics under Flu;
Flu can be otherwise called INFLUENZA; it is a contagious infection that affect the respiratory unit of the body, it is caused by viruses. The viruses enter the body through air by using the nose or the mouth as a passage after which they are spread by coughs and sneezes of an infected person.
The viruses that spread this same Flu belongs to the family of Orthomyxoviridae, they possesses a single-stranded RNA genome and they are grouped into 4 types which are;
| SYMPTOMS | FLU | COLD |
|---|---|---|
| Headache | Occur Sometimes | Occurrence is so Rare |
| Cough | Common and could be severe | Mild to moderate;Hacking cough |
| Fever | It usually last for 3-5 days | It is so rare |
| Aches | It occur often and normally severe | Slightly occur |
| Weakness | Usual occur | Occur sometimes |
| Stuffy nose | Occur sometimes | Commonly occur |
Although I mentioned the types in the Introduction/ meaning of flu but now I am going to mention and talk on them;(Note; there are some of this viruses that resembles each other) I will talk on the two at once and then talk about their differences;
Influenza A and B
| Influenza A | Influenza B |
|---|---|
| It is found both in human and animals | It is only found in human |
| Human body act as the host | Wild bird normally act as the hosts |
| They are divided into sub-types | They are not sub-divided |
| This is the most severe | This is less severe |
This type of Influenza viruses are found human and Pigs, they have 7 RNA segments and 9 proteins . The most common symptoms of Influenza C is fever, cough and rhinorrhea.
According to the world health organization this type of Influenza primarily affects animal but the cause to human has not been known.
The following antiviral drugs are recommended for the treatment of Flu by CDC;
I dont know if you may be doubting me or you might even think I just say rubbish. You know what, I have references for all I just said from CDC, WHO, VIROLOGIST BLOG.
