COVID-19 Disease

COVID-19 Disease 

Coronaviruses typically cause common cold symptoms, but two betacoronaviruses — SARS-CoV and MERS-CoV — can cause severe pneumonia, respiratory failure, and death. In late 2019, infection with a novel betacoronavirus, subsequently named SARS-CoV-2, was reported in Wuhan, China.

Since then, the US Centers for Disease Control and Prevention (CDC) and the WHO are closely monitoring the worldwide outbreak of a novel coronavirus known as SARS-CoV-2, which is causing the novel coronavirus disease 2019 (COVID-19) in humans.

The most common symptoms of COVID-19 disease are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat, or diarrhea.

On April 25, 2020, the CDC announced the expansion of the COVID-19 disease symptom list to include Fever, Cough, Breathing difficulty, Chills, Muscle pain, Headache, Sore throat, and a new diagnosis loss of taste or smell.

Additionally, the CDC says if you develop any of these emergency warning signs, seek medical attention immediately: Trouble breathing, Persistent pain or pressure in the chest, New confusion or inability to arouse, and Bluish lips or face. These symptoms may appear 2-14 days after exposure to the SARS-CoV-2 coronavirus.

The CDC announced on March 3, 2020, that a significant portion of individuals infected with the SARS-CoV-2 coronavirus lack symptoms (“asymptomatic”) and that even those who eventually develop symptoms (“pre-symptomatic”) can transmit the virus to others for several days before showing symptoms. 

This means that the virus can spread between people interacting in close proximity—for example, speaking, coughing, or sneezing—even if those people are not exhibiting symptoms. 

Furthermore, recent studies suggest that recovery from one SARS-CoV-2 infection might not protect a person against a second infection.

People at Risk from COVID-19 Disease

COVID-19 is a new disease and scientists are still learning how it spreads. Someone who is actively sick with COVID-19 can spread the illness to others, says the CDC.

  • People can catch the COVID-19 disease from others who have the SARS-CoV-2 virus.
  • The coronavirus can spread from person to person through small droplets from the nose or mouth which are spread when a person coughs or exhales.
  • About 80% of infected people recover from the disease without needing special treatment.
  • Around 1 out of every 6 people who get COVID-19 disease becomes seriously ill and develops difficulty breathing.
  • Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness.
  • Pregnant women can become infected with SARS-CoV-2 coronavirus and COVID-19 disease.
  • Children of all ages, including infants, appear susceptible to COVID-19 disease because the SARS-CoV-2 coronavirus is novel, which means infants are not able to obtain protective antibodies from their mothers.

COVID-19 Disease Diagnosis

COVID-19 disease is diagnosed when a patient is swabbed, then the sample is tested via reverse transcription-polymerase chain reaction (RT-PCR) to determine the presence of viral RNA.  Though, it’s unknown whether those people were truly reinfected or still just had low levels of the virus in their systems after they felt better.

COVID-19 Disease Fatality Rate

Older people and those with chronic medical conditions, such as heart disease, lung disease, and diabetes, appear to be at higher risk of developing serious COVID-19 illness. COVID-19 disease fatality rates range between 12% in endemic areas, such as China, Italy, and Spain, to less than 1% in passive countries.
