It's that time of year again - when family and friends start dropping like flies, victim to the inevitable winter flu.

*Shudders*

So before you head into work fraught with flu symptoms and infect your work colleagues, have a look through HuffPost Canada's comprehensive list of flu symptoms and consider quarantine...

  • Temperature

    Feeling feverish or having a fever of 100°F or higher can be an indicator for the flu or H1N1 virus, though not everyone with the flu will get a fever. Fevers are unlikely with a common cold.

  • Body Aches

    Feeling achy all over or getting a headache is another symptom of the flu or H1N1, and not generally associated with getting a cold. This tends to show as more general aches, as opposed to those confined to one area.

  • Nausea, Vomiting Or Diarrhea

    Nausea is the most symptom of the flu, and less likely to occur with a cold. However, if you're vomiting continuously, this can indicate a more severe strain of the flu, and you should seek medical help.

  • Sore Throat

    A sore throat is usually the first indicator of the beginning of illness, whether it's a cold, the flu or worse.

  • Cough

    Coughing occurs when one has a cold or the flu, though if it worsens, that can indicate a more severe strain, like H1N1.

  • Fatigue

    An intense feeling of exhaustion, like not being able to get out of bed, is a sign that you have the flu or H1N1. This does not usually occur with a cold.

  • Chills

    Chills can occur as a result of many kinds of bacterial and viral illnesses, including colds, the flu and H1N1.

  • Runny Nose

    Though a runny nose is most closely associated with a cold, it can also be part of having the flu or H1N1. Be sure to have plenty of tissues on hand to keep germs from spreading.

  • Dizziness

    Dizziness is not a normal symptom for a cold or flu, and should be treated with seriousness.

  • Dehydration

    Dehydration is a serious risk when you're ill, either because you feel too sick to drink or eat, or you've been vomiting and/or having diarrhea. Being dehydrated can indicate H1N1, and you should seek medical attention.

  • Pain In Stomach Or Chest

    Feeling pains in your stomach or chest while or immediately after you have the flu can indicate a serious complication, like pneumonia. Seek medical help immediately.

  • Blue, Purple Or Grey Lips

    Discoloured lips can indicate a lung infection, which poses a serious health risk. Be sure to seek medical attention immediately.

  • Make Yourself A DIY Germ Barrier

    To help keep the germs at bay, use a cotton swab to apply petroleum jelly to the inside of your nostrils. Voila! You've got yourself an enhanced germ barrier. Our <a href="http://www.caring.com/articles/7-ways-to-avoid-getting-sick-when-you-fly" target="_hplink">noses are often soft spots for bacteria and viruses and a small layer of jelly can act as a protective barrier. </a>

  • Sanitize

    Keep an all-natural hand sanitizer that promises to kill 99.9 per cent of germs in your pocket or purse at all times.

  • Protect The Kids

    Kids are primary germ carriers and will inevitably fall ill this season. To prevent yourself from getting sick, make sure your children are also protected either with a flu shot or medication.

  • Get Fresh With Garlic

    Bacteria love warm, humid environments. If what you've got now is a bacterial infection, garlic is a powerful, all-natural antibiotic solution. Of course we're not telling you to eat a raw clove straight — instead try adding garlic to soups, salads or your favourite pasta.

  • Reach For Probiotics

    A happy gut means a healthy immune system. Reach for probiotic supplements or yogurt. Probiotics can <a href="http://www.dailymail.co.uk/health/article-1281141/Probiotics-good-digestion-But-combat-flu-allergies-bad-breath.html" target="_blank">boost the immune system and increase resistance to the cold and flu by producing antibiotics.</a>

  • Get Some Zzzs

    Lack of sleep is proven to contribute to an unhealthy immune system. To ensure you have a congestion-free sleep, whether you're sick or not, use a nasal strip to help open your airways.

  • Sneeze In The Sleeve

    Much like hand washing, this is one of the simplest ways to help prevent the spread of germs.

  • Shower Your Nose

    Irrigate your nasal cavity with a neti-pot. It will flush out the viruses and bacteria reducing chances of impending infections.

  • Don't Forget The D

    When it comes to the flu, it’s not all about Vitamin C, Vitamin D is just as important. Since we may not get as many hours of sunshine as we do in the summertime, taking vitamin D supplements during the winter can help boost immunity and protect our bodies from catching a cold.

  • Flower Power

    Research suggests the use of a properly formulated Echinacea means fewer colds, reduced duration of cold symptoms, and less reliance on synthetic pain relievers.
