Article: You'll find a wide range of tutorials on economics on sites like YouTube. Look for videos from respected economists and professors in particular, and watch the videos to learn more. Start with introductory videos on microeconomics and macroeconomics before moving on to other videos. You want to get the basics down first. Ted Talks are also a good source of information, plus they'll keep you engaged! Many reputable websites offer information on the basics of economics, and you can find a whole world to explore. Look for websites with ".edu," ".gov," or ".org," as well as other well-respected sites such as this link: https://www.investopedia.com/university/economics/ Textbooks are a great way to learn the basics of economics, and you don't need to be in a class to buy one. Check with your friends who've taken economic classes or look at reviews to find a good textbook. Consider buying an older edition, which will have much of the same information but will be much cheaper. Try a textbook that provides an introduction to microeconomics or macroeconomics. Some classic influential textbooks include A Monetary History of the United States (1963) by Milton Friedman and Anne Schwartz for macroeconomics, Theory of Games and Economic Behavior (1944) by John von Neumann and Oskar Morgenstern for game theory, and Value and Capital (1936) by John Hicks for microeconomics. For more contemporary books, you could try Principles of Economics by N. Gregory Mankiw; the 8th edition was published in 2017. Another option is Modern Principles of Economics by Tyler Cowen and Alex Tabarrok; the 3rd edition was published in 2014. Textbooks are a great way to get an introduction to economics, but plenty of other books will give expand your knowledge. Plus, many of them won't be quite as dry as textbooks, so you'll learn more because you'll be entertained, too. For instance, Freakonomics is an enjoyable read that applies economics to pop culture. Math skills are helpful when it comes to learning economics, particularly statistics. If your math skills are lacking, consider taking a free online course to brush up. Start with where you're at and work up to harder courses. For example, you can find classes offered through sites like Khan Academy or Coursera. While not all math is relevant, you do need to understand the basics to work up to harder math. For instance, calculus and statistics are both relevant to economics. However, you don't want to jump into calculus if you don't have a solid foundation in algebra, geometry, and trigonometry. Many universities now offer free courses online that are open to the public. While these courses are not for credit, you do get much of the same information that students who attend these universities do. Generally, these classes are set up as a lecture series where you watch a set list of videos from a professor. Try looking on Coursera, MIT, Stanford, MR University, and Princeton.

Herpes simplex virus is very common and highly contagious. HSV -1 commonly affects the face, and often causes cold sores (painful blisters on the lips). HSV-2 tends to cause painful genital blisters. HSV-1 can spread through kissing or oral sex, while HSV-2 can spread through skin to skin contact with infected genitals. Be aware that HSV can have a long-dormant period. You may have contracted herpes long ago, but the virus may have stayed dormant in the nerve cells where it resides. Stress and lack of immunity (getting sick) are common triggers for activation of the virus from the dormant phase. Even if you can't remember ever being in contact with someone with HSV-1, consider if you've ever had a cold sore or fever blister. In the "prodrome" or early phase of any disease, symptoms indicate the onset of a condition. For whitlow, these symptoms usually appear 2 to 20 days after initial exposure, and include: Fever Fatigue Unusual pain Numbness Tingling in the area Once the initial prodrome phase has passed, you will see far more specific symptoms that point clearly to whitlow: Swelling, redness, and rash, with fluid filled vesicles around the area. The vesicles may rupture, and a white, clear, or bloody fluid will come out. These vesicles may merge and take on a black/brown color. Ulceration, or a break in the skin, may develop later. Symptoms can resolve from anywhere from 10 days to 3 weeks. Since whitlow is a more of a clinical diagnosis, the medical staff might not order any additional tests. Instead, the doctor will take your symptoms and medical history including an HSV diagnosis into consideration to diagnose whitlow. The doctor may also take a tube of your blood to order a complete blood count (CBC) with a differential (a count of your white blood cells). This will let them see if you have enough immune cells to fight infections, or if you have an underlying immune dysfunction that causes reoccurring infections. The doctor may want to test for herpes if you haven't been diagnosed with it. They may analyze your blood for herpes antibodies, order a PCR test (for the detection of herpes DNA), and/or order a viral culture (to see if actual herpes virus is growing from your blood).

One-sentence summary --
Recall if you've had contact with someone who has herpes. Look for early symptoms. Observe more typical whitlow symptoms in the disease phase. Get a formal medical diagnosis.
