Community transmission of COVID-19 is occurring throughout Wisconsin. Governor Evers has issued a ‘stay-at-home’ order that requires people to mostly stay at home except for essential travel like buying groceries, picking up medicine, and caring for others. Schools are closed statewide, and all bars and restaurants are closed with limited exceptions. This intense social distancing is needed now to prevent many COVID-19 infections and save lives in the coming weeks and months.

COVID-19 is a dangerous and highly contagious disease. The most common symptoms are fever and cough. Most people with COVID-19 have mild illness, but it causes serious illness in about 20%. The overall risk of dying appears to be about 1% to 2%. Adults over age 65 and people with serious medical conditions have the highest risk of severe illness or death. The risk of death is also increased for people 50-64 years old, and even younger adults can develop severe illness that requires intensive care. There is no treatment or vaccine. The only way to stay safe from COVID-19 is to avoid getting infected. 

Some people have no symptoms, but they can still spread the virus to others by talking, coughing or sneezing. The risk is highest when people are indoors and standing close (within 6 feet) of each other. Protect yourself and your family by staying at home. If you must leave home, keep a distance of at least 6 feet from other people. CDC recommends wearing a cloth facemask (not a medical facemask) in public places such as grocery stores and pharmacies.

Frequent handwashing is important. The virus can spread by touching contaminated objects and surfaces such as door handles, cups, eating utensils, and towels. Clean and sanitize objects and surfaces that are routinely touched. 

Contact your health care provider if you develop high fever, shortness of breath, or weakness. Always call your health care provider before coming to the clinic or hospital, except in an emergency. You can use our online screening tool if you have questions or need advice. If you have COVID-19 symptoms, stay in a separate bedroom if possible and away from household members. Follow these CDC recommendations if you are sick or caring for someone who is sick.

Current Situation and Recommendations

  • Over 374,000 COVID-19 cases and 12,000 deaths have been reported in the US. The true number of cases is certainly much larger. The number of cases is expected to double every week without control measures, but social distancing now will reduce the number of cases in the coming weeks. If people stay apart now, COVID-19 will infect fewer people and cases will be spread out over a longer time (flattening the curve). This helps prevent a surge of COVID-19 cases in a short time that can overwhelm hospitals and intensive care units.

  • The virus spreads easily from person-to-person, similar to the flu virus. COVID-19 commonly causes fever and cough, and it may also cause shortness of breath, sore throat, muscle aches, and feeling tired. Some people develop loss of taste or smell with COVID-19. Symptoms usually start about 4-5 days after infection, but it may take up to 14 days.

  • Intense 'social distancing' is important now to slow the spread of COVID-19 in the coming weeks and save lives. Stay at home and stay away from other people. Wear a cloth facemask if you must leave home for groceries or essential services. Wash your hands often, use a tissue for coughs and sneezes, and avoid touching your face. Use disinfectants to clean surfaces that are touched by different people.

  • Availability of COVID-19 lab testing is increasing, but laboratories still do not have the capacity to test everyone with COVID-19 symptoms. Marshfield Clinic offers clinical testing, and patients who are hospitalized are the highest priority. Due to the limited supply of tests, most people with mild respiratory illness cannot be tested.

  • Call your medical provider if you need care for cough, fever, or shortness of breath. It is important to call before coming in (except in an emergency). Contact your provider right away if you have high fever, shortness of breath, or weakness.
