Most people infected with SARS-CoV-2 start to feel sick between 2 and 14 days later. People's symptoms may get worse at different rates, but fever is usually the first sign. After about a week, the symptoms can get worse, and people who have this virus often need to be treated in the hospital. Some of these people also have respiratory distress syndrome, which means their lungs don't give their bodies enough oxygen.
One of the main signs of COVID-19 is a fever, which affects about four out of ten kids and adults (40%) at some point during their illness. Fever is a sign of an infection, but it can also mean your body is trying to fight it. Call your doctor right away if you have a high fever. They may need to take your temperature again or give you medicine to help your body fight the infection.
Most of the time, chest pain from COVID-19 feels like chest pain from a lung problem like pneumonia. It can be a sharp sting or hurt and worsens when breathing. People also often have heart palpitations. If you have COVID-19 and these symptoms, you should see a doctor as soon as possible.
Loss of appetite is a common sign of illness, but it can also mean that something else is wrong. See your doctor immediately if you lose your appetite or feel like you aren't eating enough. This study looked at how COVID-19 affected what people in Denmark said about their hunger, how they felt about their senses, and how they ate. The results show that the disease severely affects appetite during the acute and post-acute stages, as well as major changes in how people feel (e.g., taste, oronasal, retronasal, off-flavour, and chemesthesis).
Many people with COVID-19 have muscle problems that last for weeks or months after the infection. These signs may be mild, or they may be very bad. Many of these symptoms are like other problems that can happen when you have an illness that lasts for a long time. Some of these are tiredness, weakness, and muscle pain.
People with COVID-19 often feel sick, throw up, and have diarrhoea as some of their first signs. They can also happen before symptoms in the lungs, like a dry cough. It is thought that COVID-19 gets into the body through the angiotensin-converting enzyme 2 (ACE2) receptors in the digestive tract. Then, it hurts cells.
COVID often causes diarrhoea, which usually starts in the first few days after infection. It happens when the speed at which your stool moves through your intestines changes. This means it stays in your bowel longer and makes you lose water and electrolytes. So, to stay healthy, it's important to stay hydrated and drink lots of clear fluids.
One of the most common signs that someone has COVID-19 is a headache. Teshamae Monteith, MD, an associate professor of clinical neurology at the University of Miami Miller School of Medicine, says that the types of pain range from pressure to severe, throbbing pain with some migraine-like symptoms. Some people can have headaches for weeks or even months after infection. This is called long COVID or post-COVID syndrome.
People with COVID are more likely to get confused if they have other health problems. This could be a sign that their illness is worsening, which is something to worry about. If you are confused after a COVID infection, you should see a doctor immediately. They'll be able to figure out what's making you confused and how to treat it.
Coughing and difficulty breathing are frequent symptoms of COVID-19. Dyspnea is a synonym for this condition. It can vary in severity from a minor case that clears up in a few days to a severe one that leaves a person incapacitated for weeks. The lungs may be trained to function more efficiently through regular breathing exercises. Inhale deeply through your nose, then exhale slowly through your pursed lips. Repeat this process many times a day. Ideally, it would help if you aimed to exhale for twice as long as you inhale.
Coordination problems arise when persons cannot regulate their muscular activity—walking, lifting, and carrying becomes challenging for them. Injury to the cerebellum is only one of many potential triggers. Likewise, this may indicate that you struggle to cope with stress or worry. Try meditation, counselling, or medication to eliminate these issues and reduce your blood pressure.
