Answer:
cold and flu - Colds and influenza (flu) are the most common illnesses among college students. Both of these illnesses are upper respiratory infections, meaning they involve your nose, throat, and lungs. Viruses cause both colds and flu by increasing inflammation of the membranes in the nose and throat.
Most transmission of these viruses occurs via hand-to-hand contact.You may also experience a mild headache, body aches or a low grade fever. Typically, a cold lasts 2-14 days.
Conjunctivitis (“pink eye“) - Conjunctivitis, an inflammation of the transparent membrane (conjunctiva) that lines your eyelids and part of your eyeballs, has several possible causes. It could be a bacterial or viral infection, an allergic reaction to pollen or animal dander, or a result of chemical irritants (smoke, chlorine, lens solution, etc.). These symptoms may last a few hours to several weeks: redness, itching, tearing, burning sensation, pus-like discharge and/or crusting of the eyelids. Because conjunctivitis causes inflammation of the small blood vessels in the conjunctiva to become more prominent, the whites of your eyes will appear pink or red. When you wake you are likely to feel that your eyelids are pasted shut, and your vision may not be as clear as usual.
Diarrhea - Bacterial infection, caused by contaminated food or water
Viral infection
Parasites, which can enter the body through food or water
Food intolerance, such as the inability to digest lactose, the sugar in milk
Overuse of alcohol or laxatives
Medication, such as some antibiotics or antacids containing magnesium
Menstrual cramps
Stress or a panic attack
Headaches - Everyone suffers the occasional mild headache, but if you experience debilitating pain and/or abnormally frequent headaches, you probably want to find relief. There are countless causes of headaches, which differ for each person, so you’ll have to do some experimenting to figure out the cause of your pain. Fortunately, the vast majority of headaches are primary headaches, not the result of underlying medical conditions. The three most common types are cluster, tension-type, and migraine.The cause of a headache is often elusive. Although it may seem that your head is pounding for no reason, there is always an explanation for pain. To find out the cause of your headaches, keep a log. Write down the date and time each headache starts and stops, the location of the pain, the nature and severity of the pain, and any factors that seem to trigger the headaches (food, stress, menstrual cycle, medicine, etc.).Just as the causes vary for each headache sufferer, so do the symptoms and severity of pain. Health professionals can often diagnose the type of headache you suffer based on your symptoms.
Mononucleosis - Mononucleosis is an illness caused by the Epstein-Barr virus (EBV), which is spread through salivaThe most well known symptom of “mono“ is extreme fatigue, forcing the infected person to nap frequently. If you experience such extreme fatigue accompanied by other symptoms, such as swollen lymph glands and spleen, sore throat, fever, loss of appetite, and muscle aches, you may want to get tested for mono. The basis for testing whether you have mono is the presence of antibodies produced by white blood cells. Many people infected with mono don’t get sick, or have such mild symptoms they don’t know they have it. EBV is usually in the body 30-50 days before an infected person develops symptoms. Surprisingly, 80-95% of adults in the US have been infected by the time they’re 40, but only about 20% know they’ve had mono.
