Symptoms after Fever and cough

Coronavirus symptoms go beyond fever and cough

What are the symptoms of Coronavirus?

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.

Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop severe illness.

The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes, and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol-based rub frequently and not touching your face. 

The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it's essential that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).

At this time, there are no specific vaccines or treatments for COVID-19. However, many ongoing clinical trials are evaluating potential therapies. WHO will continue to provide updated information as soon as clinical findings become available.

Authorities reported a novel coronavirus in Wuhan, China last December 2019. Thousands of confirmed cases of the coronavirus disease (COVID-19) have been reported each day globally, and the numbers are still growing. The coronavirus disease or COVID-19 is a new strain that has not been previously seen in humans. Read more on the symptoms and how you can prevent the spread of this disease.

Coronaviruses (CoV) are a group of viruses that cause illnesses ranging from the common cold to more severe diseases such as the Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS CoV). Coronaviruses are zoonotic, meaning they are transmitted between animals and people. In rare circumstances, as with the MERS and SARS, animal coronaviruses can evolve and infect people and then spread between people. Although this is the case, studies from the CDC show that there is no evidence that household pets can spread COVID-19.

A coronavirus is a virus that is found in animals and, rarely, can be transmitted from animals to humans and then spread person to person. In addition to COVID-19, other human coronaviruses have included:

  • The MERS virus, or Middle East respiratory syndrome.
  • The SARS virus, or severe acute respiratory syndrome, which first occurred in the Guangdong province in southern China.
  • Coronaviruses are a family of viruses that can cause illnesses such as the common cold, severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). In 2019, a new coronavirus was identified as the cause of a disease outbreak that originated in China.
  • The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is called coronavirus disease 2019 (COVID-19). In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic.

Public health groups, including the U.S. Centers for Disease Control and Prevention (CDC) and WHO, are monitoring the pandemic and posting updates on their websites. These groups have also issued recommendations for preventing and treating the illness.

According to the WHO, coronaviruses are a family of viruses that cause illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS).

These viruses were initially being transmitted from animals to people. SARS, for instance, was transferred from civet cats to humans while MERS moved to humans from a type of camel.

Several known coronaviruses are circulating in animals that have not yet infected humans.

The name coronavirus comes from the Latin word corona, meaning crown or halo. Under an electron microscope, the looks like it are surrounded by a solar corona.

The novel coronavirus, identified by Chinese authorities on January 7 and since named SARS-CoV-2, is a new strain that had not been previously identified in humans. Little is known about it, although human-to-human transmission has been confirmed.

The rapid spread of the virus that causes COVID-19 has sparked alarm worldwide. The World Health Organization (WHO) has declared this rapidly spreading coronavirus outbreak a pandemic, and countries around the world are grappling with a surge in confirmed cases. In the US, social distancing to slow the spread of coronavirus has created a new normal. Meanwhile, scientists are exploring potential treatments and are beginning clinical trials to test new therapies and vaccines. And hospitals are ramping up their capabilities to care for increasing numbers of infected patients.Countries around the world are scrambling to halt the spread of the coronavirus pandemic.

As of April 2, more than 48,000 people worldwide have died of COVID-19, the highly infectious respiratory disease caused by the coronavirus. More than 950,000 people have tested positive for COVID-19, according to data compiled by Johns Hopkins University. 

What causes a coronavirus infection?

Humans first get a coronavirus from contact with animals. Then, it can spread from human to human. Health officials do not know what animal caused COVID-19.

The COVID-19 virus can be spread through contact with certain bodily fluids, such as droplets in a cough. It might also be caused by touching something an infected person has touched and then touching your hand to your mouth, nose, or eyes.

Chinese health authorities are still trying to determine the origin of the virus, which they say likely came from a seafood market in Wuhan, China where wildlife was also traded illegally.

On February 7, Chinese researchers said the virus could have spread from an infected animal species to humans through illegally-trafficked pangolins, which are prized in Asia for food and medicine.

Scientists have pointed to either bats or snakes as possible sources of the virus. 

How to stay away from Corona Virus

What are the symptoms?

According to the WHO, signs of infection include fever, cough, shortness of breath and breathing difficulties.

In more severe cases, it can lead to pneumonia, multiple organ failure and even death.

Current estimates of the incubation period - the time between infection and the onset of symptoms - ranging from one to 14 days. Most infected people show signs within five to six days.

However, infected patients can also be asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.

Common signs of the infection are fever, cough, shortness of breath, and difficulty in breathing. More severe cases can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

Some people infected with the virus have no symptoms. When the infection does cause symptoms, common ones include dry cough, fatigue, low-grade fever, body aches, nasal congestion, and sore throat. However, COVID-19 can occasionally cause more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia

Shortness of breath refers to unexpectedly feeling out of breath, or winded. But when should you worry about shortness of breath? There are many examples of temporary shortness of breath that are not worrisome. For example, if you feel very anxious, it's common to get short of breath and then it goes away when you calm down.

However, if you find that you are ever breathing harder or having trouble getting air each time you exert yourself, you always need to call your doctor. That was true before we had the recent outbreak of COVID-19, and it will still be valid after it is over.

Meanwhile, it's important to remember that if shortness of breath is your only symptom, without a cough or fever, something other than COVID-19 is the likely problem.

The severity of COVID-19 symptoms can range from very mild to severe. Some people may have no symptoms at all. People who are older or who have existing chronic medical conditions, such as heart disease, lung disease or diabetes, or who have compromised immune systems may be at higher risk of serious illness. This is similar to what is seen with other respiratory diseases, such as influenza.

Signs and symptoms of COVID-19 may appear two to 14 days after exposure and can include:

  • Fever
  • Cough
  • Shortness of breath or difficulty breathing

Other symptoms can include:

  • Tiredness
  • Aches
  • Runny nose
  • Sore throat

Corona Virus Symptoms

Some people have experienced the loss of smell or taste.

The COVID-19 virus affects different people in different ways. COVID-19 is a respiratory disease and most infected people will develop mild to moderate symptoms and recover without requiring special treatment. People who have underlying medical conditions and those over 60 years old have a higher risk of developing severe disease and death.

People with mild symptoms who are otherwise healthy should self-isolate and contact their medical provider or a COVID-19 information line for advice on testing and referral.

People with fever, cough or difficulty breathing should call their doctor and seek medical attention.

Many patients who've either tested positive for the coronavirus or have been told by their physicians to assume they have it, also develop a headache and sore throat. Others become sick to their stomach with nausea or diarrhea.

Some patients say they have no interest in eating. Many reports they're losing their senses of taste and smell, the British Rhinological Society noted recently.

Just this week, a small study published in JAMA Ophthalmology added another potential COVID-19 warning sign: pink eye, also known as conjunctivitis. A third of the 38 patients in the report had the inflammatory eye condition.

But it's also becoming more evident that some infected people spreading the virus don't have any symptoms at all.

When to see a doctor

If you have COVID-19 symptoms or you've been in contact with someone diagnosed with COVID-19, contact your doctor or clinic right away for medical advice. Tell your health care team about your symptoms and possible exposure before you go to your appointment.

If you have emergency COVID-19 signs and symptoms, such as trouble breathing, chest pain or pressure, confusion, or blue lips or face, seek care immediately.

If you have respiratory symptoms but you are not and have not been in an area with ongoing community spread, contact your doctor or clinic for guidance. Let your doctor know if you have other chronic medical conditions, such as heart disease or lung disease. As the pandemic progresses, it's essential to make sure health care is available for those in greatest need.

Practice social distancing. Avoid people who are sick or meeting in large groups. Stay home if you are sick. Cover your cough with a tissue or cough into your upper sleeve or elbow. Do not cough into your hands.

Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty. Avoid touching your mouth, nose, or eyes.

Experts have confirmed that COVID-19 is spread through the inhalation of the respiratory droplets of an infected person. Another established mode of transmission is close or frequent exposure to those who are ill or exhibiting similar influenza-like symptoms. Take note of the following standard precautions to avoid getting sick:

Perform hand washing regularly and thoroughly. It is advised to wash hands with soap and water for at least 40 to 60 seconds. Use hand sanitizer or 70% alcohol if soap and water are not available.

  • Practice cough etiquette. Cover your mouth and nose with tissue paper when coughing and sneezing. 
  • Boost immunity. Take multivitamins and drink lots of water.
  • Thoroughly cook meat and eggs—practice safe food preparation to minimize bacterial growth.
  • Avoid crowded places. Do not come into close contact with anyone showing symptoms of respiratory illness.
  • Get a flu shot. The influenza vaccine should be done yearly.
  • Consult your doctor. Seek advice and get a proper assessment if you have a fever, cough, and possible exposure to a patient who travelled from China.

The World Health Organization (WHO) and the Centers for Disease Control (CDC) advise international travellers to practice these usual health precautions:

  • Avoid close contact with people suffering from acute respiratory infections
  • Avoid visiting healthcare facilities in a country with cases of COVID-19
  • Practice frequent hand washing especially after direct contact with ill people or their environment
  • Avoid close contact with live or dead farm or wild animals. Touching poultry/birds or their droppings should be avoided, as well as visiting live poultry markets or farms
  • Travellers with symptoms of acute respiratory infection should practice cough etiquette (maintain distance, cover your mouth when you cough and sneeze with disposable tissue or clothing. Wear surgical masks to minimize airborne transmission of infection)
  • Immediately seek medical attention in case of symptoms suggestive of respiratory illness during or within 14 days after travel.
