Sorry I will not be coming into work today as I have gone down with flu
Sorry I will not be at work today as I am suffering from flu
There are a few different variations of saying this.
Most importantly, you should distinguish between a cold and flu.
A cold is usually considered a mild inconvenience and most people would continue working with this ailment.
Flu is a more serious blow and can badly affect people for a few days or more in some cases.
いくつか言い方があります。一番大事なのは、coldとfluを区別することです。
A coldは生活に影響は出ますが、恐らく多くの人がそれでも働くでしょうね。
しかしFluの場合、症状が重く、だいたい2、3日か、それ以上も重い症状が続くケースが多いです。
I am sorry but I will not be able to come in today. I woke up sick.

Because a cold is a viral infection which can affect one's performance at work, it is not advisable for a person to go to work when that person is suffering from it.
It should be noted that colds are highly infectious and can easily spread. To void infecting workmates, it is advisable to be on sick leave and visit the doctor.
The doctor will prescribe medicines to take to alleviate the infection and also recommend a period of rest and recovery.
Doctors give sick notes for this.
I'm feeling ill, and I don't think I can make it to work today.
You can ask for you boss to use a "sick day." You can also say that you are "calling in sick." You can also express that you're "feeling ill" and of course, apologize for any inconvenience and express gratitude to your boss for their understanding.
上司に、"sick day"（病気休暇）を使いたいことを尋ねるといいです。"calling in sick"（病欠の電話をする）と言うこともできます。また、"feeling ill"（体調が悪い）ということを表現して、当然ながら不便をかけてしまうことに謝って、上司が理解してくれることに感謝をすることもできます。

You do not always have to use the word "cold". You can state that you are sick or you are under the weather. If someone asks how you are doing and you are sick, you can say, "I am not feeling well. I am under the weather." This expression means that you are sick.
"cold"（風邪）という言葉を、いつも使わなければならないというわけではありません。. sick（気分が悪い）と言ったり、under the weather（気分が悪い）と言っても構いません。
誰かがあなたに元気か聞いてきて、あなたの気分が悪い場合は、"I am not feeling well. I am under the weather." （私はあんまり気分がよくない。気分が悪いんだ。）と言うことができます。こちらの文は、気分が悪いという表現です。
