In one sentence, describe what the following article is about: The way to determine if you have giardiasis is to combine your knowledge of your past behavior with your current symptoms and testing from your physician. Your risk of developing giardiasis increases if you or a family member member have been exposed to any of the following possible means for passing on the infection:  You've been traveling overseas or have come into contact with international travelers, particularly in close quarters. You've had contaminated water, such as drinking water or ice made from contaminated sources like roof rainwater, rivers, streams, shallow wells, etc. contaminated by infected animals or people. Alternatively, you've had untreated (non-boiled) or unfiltered water. You've had contaminated food – this can be caused by someone handling food who hasn't washed their hands after changing a diaper or going to the toilet. You've been in contact with infected people, such as caregivers or family members of infected people. You've been exposed to feces through sexual contact. You haven't washed your hands after touching animals or infected people. You have or have contact with children who use diapers and/or with children spending time in a daycare setting. You have gone hiking and been exposed to untreated sources of water. The symptoms of a Giardia infection can be non-specific. In other words, they can also mimic the symptoms of other intestinal disorders or infections.  Symptoms of the infection will usually appear between one and two weeks after exposure. This is called the incubation period, or the time it takes for the parasite to cause symptoms to occur. The most obvious signs of infection are a number of gastrointestinal symptoms, including:  Acute or chronic diarrhea with foul-smelling stool. With a Giardia infection, the stool can have a greasy appearance and blood is very rarely seen. You may find that the diarrhea alternates between watery stool and greasy, foul-smelling stool that floats in the toilet water. Abdominal cramps or pain Bloating Flatulence or passing much more gas than you normally do (the abdomen may be swollen from the gas in the intestines). Often the bloating, pain, and flatulence will all occur together. Nausea and vomiting Loss of appetite Belching gas with a very bad taste The result of the diarrhea and other abdominal symptoms can trigger the following additional symptoms of a Giardia infection:  Weight loss Dehydration Fatigue Low-grade fever or a fever less than 100.5 degrees Fahrenheit Individuals over the age of 60 often display symptoms that include anemia, weight loss and loss of appetite The very elderly and the very young can both be at particular risk for complications stemming from these secondary symptoms You may experience symptoms and then get better or you may experience a course of the illness in which you have symptoms, get better, and then feel badly again over several weeks or months.  Some people who are infected with Giardia never develop symptoms but are still carrying the parasite and are able to spread it to others through their stool. People who are asymptomatic, or don’t have symptoms, often clear the infection spontaneously. In order to prevent the spread of giardiasis, get a diagnosis from your doctor as soon as you can. Although the infection can be self-limiting and typically clears up, you can reduce your potential for experiencing a chronic infection through early diagnosis and treatment. Diagnosis is usually made via a fecal specimen, so be prepared to give a stool sample. Once you have a clear diagnosis of giardiasis, you can discuss treatment options with your physician. There are several prescription drugs that can be used to treat giardiasis, including metronidazole, tinidazole, and nitazoxanide. Different factors may affect how effective a drug regimen will be, including medical history, nutritional status, and the condition of your immune system.  Infants and pregnant women may be more likely to experience dehydration from the diarrhea caused by giardiasis. To prevent dehydration, these at-risk populations should drink a lot of fluids while ill. Children should utilize an age appropriate electrolyte replacement fluid, such as Pedialyte. If you work with children or handle food, do not return to work until you're symptom-free for two days. The same goes for children in early childhood centers. Otherwise, you can go back to work as soon as you're symptom-free.
Summary: Consider if you may have been exposed to Giardia parasites. Look for physical symptoms of giardiasis. Check for secondary symptoms related to the primary symptoms. Be aware that symptoms can change or even be absent. See a physician. Get treatment.

In one sentence, describe what the following article is about: A major factor in happiness is social contact and support. Talking to a friend about your sadness or the situation that has caused your sadness can help lessen the pain because you will know that someone cares about you and your feelings. Talking out loud can also help you "air out" your emotions and clarify exactly what you are feeling because it requires you put those feelings into words. Your sadness is no longer abstract, but becomes real, something that can be named and discussed, through its articulation in words.  Research has shown that people who experience major life stresses, such as the loss of a partner or job, come out the other side of the ordeal more easily if they have a network of friends and family on whom they can draw and rely.  You may also learn something from talking to a friend. For example, maybe your friend has experienced similar feelings or a similar situation and can offer you support and advice. Alternatively, your friend may be able to help you look at your situation from a different angle and may be able to suggest methods of coping that you had not yet thought of. If you're going through a break up, for example, maybe your friend reminds you of all of the times you called her complaining about how your boyfriend was inattentive and selfish. In this sense, your friend can help remind you of the reasons why you broke up with your boyfriend when you're stuck being sad about the breakup itself. Friends can also help you feel supported and alleviate the feeling that you are alone. They offer you a place to be heard and understood. In addition, simply talking with a friend may improve your mood since you will likely end up smiling and laughing at some point! See a movie, go for dinner, or head out for a bike ride with friends or family. Along with distracting yourself, social interaction outside will help you get out of your own head for a few hours. Just talking with others - even exchanging menial pleasantries - and a change of scenery can improve your mood. If you're a loner by nature, don't overdo it with the socializing as this might make you more stressed and anxious. Aim for limited, low-key social interaction, like running an errand, grabbing groceries, or getting a pedicure with a friend, rather than a long night of bar-hopping with friends. If you don't feel like being social with other human beings, consider spending time your cuddly pet! Cuddling or petting a favorite animal can help improve your sad mood by meeting the basic human need of connection and closeness. Research has shown that spending time with dogs increases the concentration of endorphins, chemicals that interact with the receptors in your brain to trigger positive feelings and improve your mood. Additionally, animals are particularly adept at sensing our moods through our body movements and tone of voice, so they are often “in-tune” with how we are feeling. Giving your time and energy to help others will not only help you stay busy, but will also give you a sense of reward and purpose, making you feel better about yourself and your situation.  Find a volunteer activity that you're passionate about such as helping out at a homeless shelter or food kitchen, caring for or walking stray dogs, or volunteering at a senior's home.  Even doing something small for someone else, like letting someone go ahead of you in the line at the grocery store, can make you feel better. Acts of kindness increase your sense of well-being because they are concrete things that you can do, and not just think.
Summary:
Talk to a friend. Go out and socialize. Spend time with a pet. Focus on others.
