What is going around right now in Minnesota
Across Minnesota, emergency departments and urgent care clinics typically see increases in respiratory viruses during late fall and winter. In any given week, common causes of cough, sore throat, and fever include influenza, respiratory syncytial virus (RSV), rhinovirus/enterovirus, adenovirus, and SARS-CoV-2 (COVID-19). The mix shifts seasonally: influenza and RSV often rise first, followed by increases in COVID-19 waves and common cold viruses. Current local data summaries from the Minnesota Department of Health indicate that multiple viruses are circulating at moderate to high levels statewide. This evergreen explainer outlines what these patterns usually mean, how to tell common viral illnesses apart, when to seek care, and practical steps to reduce spread in homes and communities.
How to tell the most common circulating viruses apart
Influenza (flu)
Influenza tends to cause abrupt onset of fever, chills, headache, significant muscle aches, dry cough, sore throat, and marked fatigue. Symptoms often peak within the first 3 to 5 days. Influenza is most common during winter months and spreads through respiratory droplets and contaminated surfaces. Annual vaccination substantially lowers risk of severe illness and hospitalization.
Respiratory syncytial virus (RSV)
RSV commonly causes runny nose, decreased appetite, coughing, wheezing, and sometimes fever. In infants and older adults, RSV can lead to bronchiolitis or pneumonia. Young children are at higher risk for severe disease, and RSV often increases in late fall and winter, overlapping with flu season. Supportive care such as nasal suctioning and fluids is typical; some high-risk infants may receive preventive monoclonal antibodies during peak season.
COVID-19
COVID-19 symptoms vary and can include fever or chills, cough, shortness of breath, fatigue, sore throat, congestion, headache, muscle aches, and loss of taste or smell. Many people experience mild illness, but some develop more severe respiratory complications, especially if unvaccinated or immunocompromised. Vaccination and boosters lower the likelihood of severe disease. Testing can confirm COVID-19 and guide isolation and treatment decisions.
Other common viruses: rhinovirus, enterovirus, adenovirus
Rhinovirus and enterovirus typically cause mild cold-like symptoms such as runny nose, sneezing, and mild sore throat. Adenovirus can cause fever, sore throat, conjunctivitis (pink eye), and sometimes gastrointestinal symptoms. These viruses circulate year-round, with adenovirus sometimes causing outbreaks in close-contact settings like schools and camps.
When to seek medical care
Most viral respiratory illnesses improve with rest, fluids, and symptom management at home. Seek immediate medical attention for difficulty breathing, persistent chest pain or pressure, new confusion, or lips or face turning blue. Contact a clinician promptly if symptoms are severe or worsening, if you are at higher risk for complications (including older adults, young children, and people with chronic conditions), or if fever lasts beyond a few days or recurs after improving. Clinics can offer testing and, when appropriate, treatments such as antiviral medications for influenza or COVID-19.
Prevention and household strategies that work year-round
Because several viruses circulate together, overlapping prevention measures help reduce spread. Key habits include staying up to date with recommended vaccines, frequent handwashing with soap and water, avoiding touching the face, covering coughs and sneezes, staying home when symptomatic, improving indoor ventilation, and disinfecting high-touch surfaces. In households with infants, older adults, or people with weakened immune systems, additional precautions such as masking in crowded indoor spaces and delaying visits when symptomatic can lower risk.
| Virus | Typical symptom profile | Seasonality and notes |
|---|---|---|
| Influenza | Abrupt fever, chills, headache, myalgia, dry cough, sore throat, fatigue | Winter peaks; annual vaccine available |
| RSV | Runny nose, cough, wheezing, decreased appetite, possible fever | Late fall–winter; higher risk in infants and older adults |
| COVID-19 | Variable: fever, cough, shortness of breath, fatigue, sore throat, congestion, loss of taste or smell | Year-round waves; vaccination and boosters reduce severe disease |
| Rhinovirus/enterovirus | Runny nose, sneezing, mild sore throat, cough | Common cold syndromes year-round |
| Adenovirus | Fever, sore throat, possible conjunctivitis (pink eye), GI symptoms | Year-round; can cause outbreaks in group settings |
Testing options and what results can guide
At-home rapid tests for influenza and COVID-19 are widely available in Minnesota, and some tests also detect RSV. PCR testing through a clinic or lab can provide more detailed information, especially when results will change management. A negative rapid test does not fully rule out infection, particularly early in illness or with new variants. Testing helps inform isolation duration, eligibility for antiviral treatments, and infection control decisions at home and in healthcare settings.
Community impact and when to follow local updates
Local health departments and hospitals monitor emergency department visits, test positivity, and wastewater levels to assess regional trends. These indicators help officials refine guidance on masking, testing, and treatment access. Check the Minnesota Department of Health website for recent summaries on respiratory virus activity if you want context specific to your county or community. Individual risk and precautions may vary by age, vaccination status, and underlying conditions.
