So, it's cold and flu season. That sucks. But whenever I feel crappy, I can't tell if

感冒與流感的季節到了。煩死人了，但每次我全身無力的時候，我都不能確定

I've got the cold, or the flu -- does it matter? What's the difference?!

我得了感冒還是流感 -- 這有關係嗎？它們有什麼差別？

When I get a cough, or a headache or whatever for a few days, I always assume it will go

每當我連續好幾天咳嗽、頭痛或是有其他症狀，我都會認為很快就會好了

away, or that I just have a cold… but sometimes… it's actually the FLU! Even though the medicine says

或覺得我只是感冒了...但有時候...其實是流感！儘管醫生說

its for both the cold and the flu, they're entirely different viruses. The common cold

我得的是感冒，也是流感，但它們其實是完全不同的病毒。一般常見的感冒

is caused by over 200 different viruses! Coronaviruses, rhinoviruses, metapneumoviruses, enteroviruses

是由超過200種不同的病毒引起的！冠狀病毒、鼻病毒、間質肺炎病毒、腸病毒

and parainfluenza viruses all make the short list; but they really are all different.

還有副流行性感冒病毒，看起來不多，但它們真的都不一樣。

This is why we can't "cure" the common cold. The flu, on the other hand, is caused by influenza viruses.

這就是為什麼我們不能「治癒」一般感冒。另一方面，流感是由流感病毒引起的

These respiratory viruses invade the body and set up shop and cause very similar

這些呼吸道病毒會入侵身體、安置體內並引發非常相似的

symptoms, because the human body only has so many ways to fight.

症狀，因為人體只有那些反擊的方法。

When your body is invaded by a virus, chances are you'll get the same symptoms every time,

病毒入侵你身體時，很可能每次出現的症狀都一樣

dry or sore throat, coughing and sneezing, mild fever, congestion and maybe a headache.

喉嚨乾或痛、咳嗽打噴嚏、輕微發燒、鼻塞，也許還會頭痛

Pretty standard stuff. If it's REALLY bad, you'll get aches and pains in your muscles and exhaustion too.

都是很制式化的現象。如果症狀真的很糟，你可能還會肌肉痠痛並全身無力

This happens because your body is spending resources fighting off that viral infection.

這是因為你的身體正在努力對抗病毒感染

In general, flu is worse than the common cold, the fever is higher, the aches and level of

流感通常比一般感冒更糟，發燒的溫度更高、痠痛跟無力感

exhaustion are more pronounced, and the cough can be more intense. While there's almost

的程度更高、咳嗽更嚴重。好像沒有什麼辦法

no way to tell the difference between the two infections,really? Colds do tend to produce a

可以分辨感冒跟流感的差別，真的嗎？感冒時發燒通常

fever less than 101 (38C), affects the throat and cause a runny nose. The flu, affects the

低於38度，伴隨喉嚨不適跟流鼻水。流感則會影響

lungs and the joints -- so you're likely to feel more achy than leaky.

肺跟關節 -- 所以你可能會覺得全身無力

Telling the difference is one thing, but once you're infected you only have a couple days

分辨出差別是一回事，但只要你被傳染，你最好在幾天內

to get treatment. After the first 48 hours, the infection has usually stopped multiplying

看醫生或吃藥。起初的48小時之後，感染狀況通常不會再變化

and is wreaking havoc on the body instead. Regardless, once symptoms start for viral

而是開始在體內加劇作用。不管怎樣，只要病毒感染的症狀出現

infections, there's no simple cure. Antibiotics WILL NOT HELP, because they fight BACTERIA

就不容易痊癒。抗生素沒有用！因為它們是用來殺死細菌的！

not VIRUSES. Taking an antibacterial drug during a viral infection is pointless.

不是病毒！受病毒感染時吃抗生素沒有意義

In fact, a lot of the remedies for colds and the flu aren't really based on… well, science.

事實上，很多感冒和流感的偏方並非科學有效的方法

Many people take vitamin C like it's going out of style, but a study from the University

每況愈下時很多人會吃維他命C，但阿爾伯塔大學

of Alberta looked at results and found there's really no evidence that it helps. Results

一項研究結果顯示沒辦法確證這個方法有效。結果

suggest it MIGHT help with marathon runners who have compromised immune systems due to

指出對身體疲憊而免疫力降低的馬拉松選手來說可能有幫助

exhaustion, but even then it's minor. I like to take zinc when I'm starting to feel

但即使如此，這也只是輔助而已。我開始生病的時候會吃鋅錠

ill, and science DOES support that. Zinc is used by human immune cells as a catalyst,

而科學證明鋅錠是有效的。人體免疫細胞會把鋅當作媒介

so when you boost the amount of zinc your immune cells have more to do better,

所以你吃下鋅錠時，你的免疫細胞可以更有效地運作

but too much can actually damage your body -- so don't overmedicate.

但如果吃太多會傷害身體 -- 所以不要吃太多保健食品

In the end, a cold will persist for 10 days, while some flu symptoms will persist for three weeks;

最後，感冒會持續約10天，而有些流感症狀則會持續約三週

long after the influenza virus has been eradicated, by the way. If you REALLY want to avoid

順帶一提，比根除流感病毒還要久。如果你真的想要避免

getting sick, get a flu vaccination. Only 30 percent of surveyed adults get vaccinated

生病，就去接踵流感疫苗。根據調查，每年只有30%的成人

year over year. Flu vaccines are made every year by specialists who use massive datasets

接踵疫苗。流感疫苗每天都由專家製成，他們研究大量數據

to predict which influenza viruses will dominate this season -- see, there's more than one mutation,

以預測這一季的流感狀況 -- 看吧，會有不只一種變化

and they vie for power and bodies to infect. The 2014 flu vaccine will protect

而且它們蓄勢待發。2014年流感疫苗

against Influenza A H1N1 and H3N2, as well as a couple influenza B viruses. You might

針對H1N1和H3N2流感而製，還有一些B型流感病毒。你可能

recognize H1N1, we're still seeing that left over from 2009's unexpected flu epidemic!

知道H1N1，我們現在還有2009年突發流感的遺留病例

Pretty crazy right?

很瘋狂吧？

So yes, there IS a difference between colds and flu, but if you catch one of the over

所以，沒錯，感冒跟流感之間的確有差別，但如果你被超過200種病毒

200 viruses that cause these crappy feelings the best way to handle it is to drink fluids

的其中一種感染而引發身體不適，最好的方法就是多喝水

and help keep yourself hydrated and rest. If you minimize nutritional strain on your

讓自己持續攝取水份並好好休息。你至少可以喝雞湯

immune system by enjoying warm chicken soup and let your immune system do it's work, you'll be fine.

來保持你的免疫系統正常，並讓它發揮作用，那你就不會有事

Empathy can also help, studies have shown people who have families or even an

同理心也有幫助，研究顯示有家人關照或是看診醫生

empathetic doctor recover faster than those who don't so help out a friend if they're

特別有同理心的病人痊癒的比生病時沒有朋友幫忙的人快

sick, but don't catch it yourself. If you insist on medication, decongestants and antihistamines

但不要太在意這個。如果你堅持認為藥物治療、解充血藥跟抗組胺劑

will treat the symptoms of both cold and flu, but again -- don't take antibacterial meds

可以治療感冒跟流感的症狀，但我再說一次 -- 除非你確定是細菌感染

unless you know it's a bacterial infection because it won't help, viruses don't responses to that -- that's something a doctor can tell you.

否則不要吃抗生素，因為它對病毒根本沒用 -- 這些都是醫生會跟你說的資訊
