Stay home if you have a fever over 100 °F (38 °C). Fever is your body’s natural reaction to an infection or an illness. If you have a high fever, you are most likely contagious and you need to stay home from work or school to avoid spreading your illness to anybody else.[1] X Research source Stay at home until your body temperature gets back to a normal range and stays there for 24 hours, which is usually around 98 °F (37 °C). Taking medication to reduce your fever does not make you less contagious. A high fever is also likely to be accompanied by periods of sweating and chills. Avoid leaving your home if you have uncontrollable coughing. If you have a cough that you aren’t able to control, or your cough is accompanied by scratchiness in your throat or difficulty breathing, it could be a sign of a respiratory illness, many of which are highly contagious. Stay home from work or school so you don’t spread anything to the people who are in proximity to you.[2] X Research source Mild coughing frequently occurs due to a cold or allergies. You may also have a stuffy, drippy nose and sneezing. If you feel up to it and no other symptoms are present, you can still go about your

daily routine. Coughing that feels like it comes from deep within your lungs could be a sign of a serious infection. Some illnesses, like the flu, also feature coughing as an illness. Contact your doctor to see if you should get your cough checked out. Cover your mouth when you cough and wash your hands frequently. This will help prevent you from spreading germs and viruses. If you have trouble breathing during coughing fits, go to the emergency room to get medical attention. Keep away from other people if you’re vomiting regularly. Persistent vomiting will dehydrate you and make you feel weak, as well as being a sign that you have a contagious illness. If you’re unable to hold any food down, stay home, rest, and hydrate so you can recover and won’t spread your illness to another person.[3] X Research source Take care of yourself by drinking plenty of liquids. If you can’t keep a glass of water down, you might try sucking on ice cubes to make it easier to keep down. If you are unable to keep any liquid down and are at risk of becoming severely dehydrated, you may need to go to an emergency room.. Symptoms of dehydration include weakness, headaches, infrequent urination,

passing dark or cloudy urine, and crying without tears. Take a sick day if you have diarrhea. A very loose or watery stool can often be a sign of infection and the extra water that you lose can dehydrate you. It’s best for you to remain at home near a bathroom, so don’t try to go to work or school until you stop having diarrhea and feel better.[4] X Research source If the diarrhea is caused by food or medication, then it’s not contagious. In this case if you are well enough to be able to go about your daily routine, you do not need to stay home unless you will not be able to use the toilet when you need it if you go out. It’s important to replenish your liquids by drinking lots of water, even if you don’t feel thirsty. Wait until your doctor says your child can return to school. If your child has an illness or disease that was treated by a doctor, keep them home until your doctor clears them to go back to school or daycare. If your child comes into contact with other children who weren’t vaccinated for a disease or have weakened immune systems, then your child could spread it to them. Additionally, if your child is recovering from cold, flu, or another illness, they

could potentially spread it, even if they’re feeling better. Wait until their doctor says it’s safe for them to return.[5] X Research source For some illnesses or conditions, such as scabies, lice, and Fifth’s Disease, it’s safe to send your child back to school after they start treatment.

Once your child has begun treatment, they may be able to go back to school once your doctor says they are unlikely to be infectious. Keep your child at home for 1 day after being treated for impetigo. Impetigo is a common skin infection that affects children and babies and usually appears as red sores around the mouth as well as on

stay home if you just have a cold. But, even if you feel well enough to go to work or school, there are some simple precautions that you can take to protect others, including:[9] X Research source Washing your hands frequently Not hugging or shaking hands Avoiding sharing drinks or food with others Sneezing or coughing into your elbow instead of your hands Using tissues if you have a drippy nose Avoid getting too close to people when you are sick. If you must go to work or school when you are sick, you can still minimize the chances that you will infect others by keeping a distance. Many illnesses can be passed to other people simply by coming into contact with you, so maintaining social distancing can help prevent their spread. You can:[10] X Trustworthy Source Centers for Disease Control and Prevention Main public health institute for the US, run by the Dept. of Health and Human Services Go to source Avoid giving hugs. If necessary, you can explain to people that you feel a little unwell and don’t want to infect them. Chances are they will agree that it is best if you stay away. Don’t lean into people when talking or looking over their shoulder at a computer screen. Wear a

face mask, to prevent accidentally breathing on others.[11] X Trustworthy Source Centers for Disease Control and Prevention Main public health institute for the US, run by the Dept. of Health and Human Services Go to source Minimize the amount of handshaking you do. Cover your mouth when you cough or sneeze. Coughing or sneezing expels mucous, germs, bacteria, and viruses from your nose, mouth, and lungs into the air around you, which can spread your illness to other people. Cover your mouth with a tissue and throw it away afterwards or sneeze or cough into your elbow, which is much less likely to come in contact with other people and communal surfaces than your hands.[12] X Trustworthy Source Centers for Disease Control and Prevention Main public health institute for the US, run by the Dept. of Health and Human Services Go to source If you cough or sneeze uncontrollably, wear a face mask. Wipe down communal surfaces that you touch such as tables, desks, computer keyboards, and doorknobs with disinfectant wipes. Wash your hands often and thoroughly. Washing your hands is the simplest and one of the most effective ways you can prevent the spread of germs, bacteria, and viruses that

can make other people sick. Wash your hands before you prepare food, after you use the bathroom, after you blow your nose, after you sneeze or cough, before you touch another person, or anytime you touch a surface.[13] X Research source Go to the doctor if there are signs of a serious infection or complications. Serious infections can be life-threatening and may only be treated with antibiotics that are prescribed by a doctor. If you or your child have any of these symptoms, see a doctor:[14] X Trustworthy Source Centers for Disease Control and Prevention Main public health institute for the US, run by the Dept. of Health and Human Services Go to source Difficulty breathing Fast breathing A bluish tinge to the skin Dehydration Unresponsiveness or unable to wake up Extreme irritability Fever for more than 3 days Fever with a rash Flu-like symptoms that go away, then come back with a fever and bad cough Pain in the abdomen or chest Pressure in the abdomen or chest Dizziness Confusion Severe vomiting Listlessness Severe head or throat pain Contact your doctor and stay at home if you have a strange rash. If you have a rash that has open wounds with fluid leaking out or is rapidly

spreading, you should call your doctor. Do not go into work or school until your doctor determines that it is not contagious.[15] X Research source Rashes due to allergies are not contagious.
