Signs of Coronavirus COVID-19

COVID-19 is a respiratory condition caused by a coronavirus. Some people are infected but don’t notice any symptoms. Most people will have mild symptoms and get better on their own. But about 1 in 6 will have severe problems, such as trouble breathing. The odds of more serious symptoms are higher if you’re older or have another health condition like diabetes or heart disease.

Here’s what to look for if you think you might have COVID-19.

Common Symptoms

Researchers in China found that the most common symptoms among people who were hospitalized with COVID-19 include:

  • Fever: 99%
  • Fatigue:70%
  • A dry cough: 59%
  • Loss of appetite: 40%
  • Body aches: 35%
  • Shortness of breath: 31%
  • Mucus or phlegm: 27%

Symptoms usually begin 2 to 14 days after you come into contact with the virus.

Other symptoms may include:

Emergency Symptoms

Call a doctor or hospital right away if you have one or more of these COVID-19 symptoms:

You need medical care as soon as possible. Call your doctor’s office or hospital before you go in. This will help them prepare to treat you and protect medical staff and other patients.

Strokes have also been reported in some people who have COVID-19. Remember FAST:

  • Face. Is one side of the person’s face numb or drooping? Is their smile lopsided?
  • Arms. Is one arm weak or numb? If they try to raise both arms, does one arm sag?
  • Speech. Can they speak clearly? Ask them to repeat a sentence.
  • Time. Every minute counts when someone shows signs of a stroke. Call 911 right away.

Lab tests can tell if COVID-19 is what’s causing your symptoms. But the tests can be hard to find, and there’s no treatment if you do have the disease. So you don’t need to get tested if you have no symptoms or only mild ones. Call your doctor or your local health department if you have questions.


Other COVID-19 Symptoms

COVID-19 can also cause problems including:

Some doctors are reporting rashes tied to COVID-19, including purple or blue lesions on children’s toes and feet. Researchers are looking into these reports so they can understand the effect on people who have COVID-19. 

Symptoms in Children

Researchers say kids have many of the same COVID-19 symptoms as adults, but they tend to be milder. Common symptoms in children include:

  • Fever: 56%
  • Cough: 54%
  • Shortness of breath: 13%

Some children and teens who are in the hospital with the disease have an inflammatory syndrome that may be linked to the new coronavirus. Doctors call it pediatric multisystem inflammatory syndrome (PMIS). Symptoms include a fever, a rash, belly pain, vomiting, diarrhea, and heart problems. It’s similar to toxic shock or to Kawasaki disease, a condition in children that causes inflammation in blood vessels.

How to Check for Fever

Your regular body temperature may be higher or lower than someone else’s. It also changes throughout the day. Doctors generally consider a fever in an adult to be anything over 100.4 F on an oral thermometer and over 100.8 F on a rectal thermometer.

If you think you’ve come into contact with the virus, or if you have symptoms, isolate yourself and check your temperature every morning and evening for at least 14 days. Keep track of the readings. A fever is the most common symptom of COVID-19, but it’s sometimes below 100 F. In a child, a fever is a temperature above 100 F on an oral thermometer or 100.4 F on a rectal one.

What Kind of Cough Is Common?

Early studies have found that at least 60% of people with COVID-19 have a dry cough. About a third have a cough with mucus, called a “wet” or “productive” cough.


What to Do If You Think You Have Mild Symptoms

If you have milder symptoms like a fever, shortness of breath, or coughing:

  • Stay home unless you need medical care. If you do need to go in, call your doctor or hospital first for guidance.
  • Tell your doctor about your illness. If you’re at high risk of complications because of your age or other health conditions, they might have more instructions.
  • Isolate yourself. This means staying away from other people as much as possible, even members of your family. Stay in a specific “sick room,” and use a separate bathroom if you can.
  • Wear a cloth face covering if you have to be around anyone else. This includes people you live with.
  • Rest up, and drink plenty of fluids. Over-the-counter medicines might help you feel better.
  • Keep track of your symptoms. If they get worse, get medical help right away.

What Does Shortness of Breath Feel Like?

Dyspnea is the word doctors use for shortness of breath. It can feel like you:

  • Have tightness in your chest
  • Can’t catch your breath
  • Can’t get enough air into your lungs
  • Can’t breathe deeply
  • Are smothering, drowning, or suffocating
  • Have to work harder than usual to breathe in or out
  • Need to breathe in before you’re done breathing out

Is It COVID-19, the Flu, a Cold, or Allergies?

Since they share so many symptoms, it can be hard to know which condition you have. But there are a few guidelines that can help.

You may have COVID-19 if you have a fever and trouble breathing, along with the symptoms listed above.

If you don’t have problems breathing, it might be the flu. You should still isolate yourself just in case.

It’s probably allergies if you don’t have a fever but your eyes are itchy, you’re sneezing, and you have a runny nose.

If you don’t have a fever and your eyes aren’t itchy, it’s probably a cold.

Call your doctor if you’re concerned about any symptoms. COVID-19 can range from mild to severe, so it may be hard to diagnose. Testing could be available in your area.

How to Protect Yourself

Take these steps to prevent COVID-19:

  • Wash your hands often, for at least 20 seconds each time, with soap and water.
  • Use an alcohol-based sanitizer with at least 60% alcohol if you don’t have to soap and water handy.
  • Limit your contact with other people. Stay at least 6 feet away from others if you have to go out.
  • Wear a cloth face mask in public places.
  • Avoid people who are sick.
  • Don’t touch your eyes, nose, or mouth unless you’ve just washed your hands.
  • Regularly clean and disinfect surfaces that you touch a lot.


Caring for Someone Who Has COVID-19 Symptoms

If you’re taking care of someone who’s sick, follow these steps to protect yourself:

  • Limit your contact as much as you can. Stay in separate rooms. If you have to be in the same room, use a fan or an open window to improve air flow.
  • Ask the person who’s sick to wear a cloth face mask when you’re around each other. You should wear one, too.
  • Don’t share items like electronics, bedding, or dishes.
  • Use gloves when handling the other person’s dishes, laundry, or trash. When you’re done, throw away the gloves and wash your hands.
  • Regularly clean and disinfect common surfaces such as doorknobs, light switches, faucets, and countertops.
  • Take care of yourself. Get enough rest and nutrition. Watch for COVID-19 symptoms.

Managed IT Services Outsourcing for Companies of All Sizes

IT Support and Security

Just about any area of your business can be hectic and prone to stress, but there’s a special kind of pressure that accompanies IT security. This pressure is consistent across all types and sizes of businesses. When a server goes down in the middle of a workday, it means instant losses in productivity and eventually sales. Plus, fixing a down server can be disruptive and confusing; it can even leave your data vulnerable.

Besides keeping your technology up and running, IT professionals face constant pressure to stay one step ahead when it comes to new technology, industry best practices and security. And don’t forget about the end-users. They need help and guidance as they learn how to use your business technology while keeping sensitive data secure. With all that, it’s no surprise there’s a growing number of businesses choosing to work with Managed IT service providers. Marco has the resources to keep your business secure, you have more than enough on your plate.

Stay Ahead Of Cyber Criminals

Security is a hot topic when it comes to business technology, but did you know it isn’t just giant corporate companies at risk? Small to medium-sized companies are prime targets too because many lack security practices employed by big business.

With Marco’s Managed IT, you can rest easy knowing Marco security experts have your back.

Enterprise-Level and Small Business Security Support

Marco’s Managed IT Services are developed to fit the needs of businesses of all sizes. We work with enterprise-level organizations that want to eliminate the time-consuming, day-to-day tasks for their internal staff. On the other end of the spectrum, small businesses that don’t have an information technology department can outsource IT help through Managed Services. Talk about efficient.

Any business, regardless of size, has probably struggled to recruit and hire internal IT staff who have the right capabilities and qualifications for the organization. Managed IT Services is a cost-effective, long-term solution for businesses experiencing staffing issues. From small business support to enterprise-level organizations, Managed IT can be as comprehensive as you need it to be. 

IT Expertise with a Proactive Approach

With over 750 factory-trained, certified systems engineers and technical representatives on staff, we don’t outsource our services. Our network of professionals is certified at the highest level for all areas of expertise. Because we put in the effort to know your technology inside and out, we’re qualified to fix problems on the spot instead of running through checklists.  

Many of our clients wonder about the comparison of break/fix versus Managed IT Services. Break/fix is a model where solutions to IT problems are figured out after a problem has already occurred. If you’ve ever encountered a broken piece of business technology and worked to solve it, you’ve experienced break/fix. In other words, break/fix is a reactive way of managing IT needs. This automatically puts your business at risk.

The Managed IT model, on the other hand, is a proactive approach to business IT. With the use of 24/7 monitoring, Managed IT makes it possible to find small issues before they become big problems. Instead of waiting for something to break, we figure out which areas are vulnerable and fix them before a large problem occurs. Managed IT is anything but break/fix.

No Worries, You’re Covered

Most providers only support certain components in their Managed IT plan. They’ll cover these desktops and those servers, but not this router or that switch. Marco is not most providers. We’re different. It doesn’t matter what hardware or software you’re using; we’ll provide support. This means you never have to worry about which vendor is maintaining what technology. We’ve got you covered.

Managed IT Services makes it possible to outsource the day-to-day technical management of a business. As a proven, strategic method for advancing operations and cutting expenses, businesses of all sizes find value in outsourcing IT. Take a look at the individual components that make up our Managed IT Services offering.
