Should I go to work with a fever of 99? The definitive guide to making the right call

4 min read

A person's normal body temperature can fluctuate throughout the day, often between 97°F and 99°F. Given this natural variation, determining when to stay home requires more than just a single reading. So, should I go to work with a fever of 99?

Quick Summary

A temperature of 99°F is typically not considered a fever by medical standards, but other symptoms are the key indicator. Assess your overall well-being and consider your potential to spread illness to others before heading to the office to make a safe, informed decision.

Key Points

  • 99°F is Not a Fever: A temperature of 99°F is typically within the normal body temperature range and not medically defined as a fever, which is 100.4°F or higher.

  • Evaluate Other Symptoms: The decision to stay home should be based on your overall symptoms (like coughing, fatigue, or body aches), not just a low temperature reading.

  • Consider Contagiousness: Many illnesses are most contagious during the early stages, so if you feel unwell, staying home prevents spreading germs to your colleagues.

  • Prioritize Rest for Recovery: Pushing yourself to work while feeling sick can prolong your illness and potentially lead to more serious complications.

  • Check Company Policy: Always consult your workplace's sick leave policy, as some employers have specific rules regarding illness and attendance.

  • Practice Common Sense: If you feel genuinely sick, regardless of the exact temperature, it is best to stay home and rest. When in doubt, stay home.

Understanding Body Temperature: What Is a Real Fever?

Before you can decide if you should go to work with a temperature of 99, it's crucial to understand what a fever truly is. Medically, a fever is generally defined as a body temperature of 100.4°F (38°C) or higher. Anything below that is usually considered a low-grade temperature or even within the normal range of fluctuation. Factors like time of day, physical activity, and hormonal cycles can cause minor variations.

Your Temperature vs. Your Other Symptoms

While a 99°F reading may cause you concern, it's the full picture of your health that matters most. If you have a 99°F temperature but feel well and have no other symptoms, it's likely not a cause for alarm. However, if that same reading is accompanied by other signs of illness, such as a sore throat, coughing, fatigue, or body aches, you should reconsider going into work. These additional symptoms suggest your body is actively fighting an infection and you may be contagious, regardless of your temperature.

The Responsibility to Protect Your Coworkers

One of the most important considerations is the health of those around you. The potential to spread illness is a major factor in the decision-making process. Even if your symptoms seem mild, you could be contagious. Many viruses, including the common cold and flu, are most easily transmitted in the early stages of illness, which is when you may only experience mild symptoms or a low-grade temperature. Protecting vulnerable coworkers, such as those with compromised immune systems, the elderly, or pregnant individuals, is a key ethical and professional responsibility.

Knowing Your Workplace Policy

Before calling in sick, you should always consult your company's policy on illness. Many employers have specific guidelines regarding when an employee should stay home. Some may require a specific temperature threshold, while others focus on the absence of contagious symptoms. Understanding your policy in advance can save you stress and ensure you are in compliance. For example, some workplaces, especially in healthcare or food service, have stricter regulations to protect the public.

When to Consider Remote Work

For many office-based jobs, remote work may be an option. If you feel well enough to work but have minor, non-contagious symptoms, and your employer permits it, working from home can be a good compromise. This approach allows you to rest and recover without exposing your colleagues to any potential pathogens. It's a pragmatic solution that balances productivity with health and safety.

Comparison: Making the Right Call

Here’s a comparison table to help you decide what to do with a 99°F temperature:

Factor Condition 1: Isolated 99°F Condition 2: 99°F with Other Symptoms
Temperature 99°F, potentially from normal fluctuations. 99°F, likely a sign of early illness.
Other Symptoms None, or very mild and non-specific. Cough, sore throat, fatigue, body aches, headache, or chills.
Contagiousness Unlikely to be contagious. Likely contagious, especially in the first few days of symptoms.
Energy Level Feeling normal or only slightly tired. Feeling weak, run down, and lethargic.
Action Step You can likely go to work. However, monitor yourself throughout the day for changes. Stay home. Your body needs rest to fight the infection and you should avoid spreading germs.
Workplace Policy Follow normal procedures. Consult sick leave policy. Remote work may be an option if you feel up to it and are not contagious.

Prioritizing Rest for a Quicker Recovery

Pushing yourself to work when your body needs rest can have negative consequences for your health. A low-grade temperature and other early symptoms are your body's signal that it is fighting an infection. Ignoring these signals can prolong your illness and potentially lead to more severe complications. Taking a sick day at the first sign of illness allows your immune system to focus on recovery, which can lead to a quicker and more complete return to health.

Long-Term vs. Short-Term Thinking

When faced with the decision, it's helpful to consider the long-term perspective. Missing one day of work to rest and recover is almost always better than pushing through and potentially being out for a longer period with a more severe illness. The added risk of infecting your entire team and causing a larger outbreak at your workplace should also factor into your decision-making. Your long-term health and the health of your colleagues are far more valuable than a single day of productivity.

A Final Word on Common Sense

Ultimately, the decision of whether to go to work with a temperature of 99°F requires you to listen to your body and use common sense. If you feel unwell, regardless of the exact number on the thermometer, staying home is the safest and most considerate choice. A low-grade temperature combined with any other flu-like symptoms is a strong indicator that you should rest and avoid contact with others. When in doubt, err on the side of caution.

Conclusion

Deciding whether you should go to work with a fever of 99 comes down to a careful assessment of your overall health and a sense of responsibility to others. While a temperature of 99°F alone is not a cause for alarm, accompanying symptoms should prompt you to stay home and rest. By prioritizing your health and the well-being of your coworkers, you can recover faster and prevent the spread of illness in your workplace. Remember, when you feel sick, stay home. It's the best decision for everyone involved.

Frequently Asked Questions

No, a temperature of 99.1°F is not considered a medical fever. Normal body temperature can fluctuate, and many health professionals consider a true fever to start at 100.4°F or higher.

You should consider staying home if your 99°F temperature is accompanied by other illness symptoms, such as coughing, sore throat, severe fatigue, or body aches. These symptoms are stronger indicators of being contagious than the low temperature alone.

The Centers for Disease Control and Prevention (CDC) generally recommends staying home until you have been fever-free for at least 24 hours without the use of fever-reducing medication.

Yes, it is possible to be contagious even with a low-grade temperature or no fever at all. Many viruses are spread most effectively in the initial days of symptoms, which may be mild.

A low-grade temperature is typically a reading between 99.0°F and 100.4°F. A fever is medically defined as a temperature of 100.4°F or higher. The presence of other symptoms is the key differentiator.

If your coworkers are sick, practice good hygiene by washing your hands frequently and avoiding touching your face. Maintain a safe distance and consider wearing a mask if you are concerned about exposure.

While not a common cause, significant stress can sometimes influence body temperature and contribute to a low-grade reading. It is important to consider all potential factors affecting your health.
