Red flags & when to go in person for Fever

Audience: adult

A fever is a common symptom that often signals your body is fighting an infection. Many fevers can be managed safely at home or through telemedicine visits. However, some signs mean you should seek in-person medical care promptly. These include very high temperatures, difficulty breathing, severe headache, confusion, or persistent vomiting. Telemedicine can help assess milder fevers, provide advice on symptom relief, and guide when to get further care. Knowing the red flags and preparing for your tele-visit can help you get the right care at the right time. Always trust your instincts and seek emergency care if you feel seriously unwell.

Red flags — go in person / ER

• Fever above 39.4°C (103°F) that does not improve with medication — seek urgent medical evaluation.
• Difficulty breathing or chest pain — go to emergency care immediately.
• Confusion, difficulty waking, seizures, or stiff neck — urgent in-person assessment needed.

What telemedicine can do

• Mild fever with no severe symptoms
• Providing advice on symptom management
• Assessing need for further testing or in-person care
• Follow-up for improving symptoms

What telemedicine cannot do

• Signs of serious infection or complications
• Respiratory distress or chest pain

What is a Fever?

A fever is when your body temperature rises above the normal range, usually over 38°C (100.4°F). It is a natural response to infection or inflammation. Fevers often come with chills, sweating, or feeling warm. They can be caused by viruses, bacteria, or other illnesses.

When to Use Telemedicine for Fever

Telemedicine is useful for mild fevers without severe symptoms. A healthcare provider can ask about your symptoms, medical history, and suggest home care tips. They can also help decide if you need tests or in-person care. Telemedicine is convenient and reduces exposure to others when you are sick.

FAQs

Can I treat a fever at home without seeing a doctor?

Many fevers can be managed safely at home with rest, fluids, and over-the-counter fever reducers like acetaminophen or ibuprofen. However, if you have red flag symptoms or your fever lasts more than a few days, you should seek medical advice.

When should I go to the emergency room for a fever?

Go to the emergency room if you have a very high fever (above 39.4°C or 103°F) that doesn’t improve, difficulty breathing, chest pain, confusion, seizures, or persistent vomiting. These signs may indicate a serious condition.

Is telemedicine safe for evaluating my fever?

Telemedicine is a safe and convenient way to get advice for mild fevers and to decide if you need further care. However, it cannot replace in-person exams when serious symptoms are present.

What should I do if my fever comes back after feeling better?

If your fever returns or symptoms worsen after initial improvement, contact your healthcare provider. This may indicate a secondary infection or complication requiring further evaluation.
