Covid-19: Symptoms, Incubation Period, and Protective Measures - What knows about Coronavirus.

The lung disease Covid-19 and the coronavirus Sars-CoV-2 continue to spread. What knows so far about the symptoms of Covid-19.
Corona viruses were first identified in the mid-1960s
The symptoms of the coronavirus-induced disease Covid-19 resemble pneumonia.

What is the new virus? An overview.
Symptoms and Disease: What is the Novel Coronavirus Sars-CoV-2?
Corona viruses are not new: According to the Robert Koch Institute (RKI), they were first identified in the mid-1960s. They are so named because they are surrounded by jagged structures that resemble a crown. Corona viruses can infect humans and various animals.
It causes various diseases in humans and has different symptoms - from harmless colds to potentially fatal diseases such as Mers (Middle East Respiratory Syndrome) and Sars (Severe Acute Respiratory Syndrome). As the RKI writes, coronavirus-like diseases like Mers and Sars have been less easily communicable than the flu in the past, but they have led to major outbreaks.

How the Sars-CoV-2 Coronavirus transmits?

The Sars-CoV-2 coronavirus seems to have been transmitted from an animal to a human in a market. However, the corona virus can also be transmitted from person to person, as has been found. Exactly how exactly the virus is transmitted is further lacking, according to the RKI. However, corona viruses are usually transmitted by droplet or smear infection. There are currently also some cases in which people have contracted patients who apparently had no symptoms. 


Sars-CoV-2: What are the symptoms of Covid-19 lung disease?
While common coronaviruses usually have symptoms of a mild cold with cough and runny nose, certain coronaviruses can cause serious lower respiratory tract infections and pneumonia. As the RKI reports, the new coronavirus Sars-CoV-2 appears to cause a more severe course of the disease. According to the information, patients who have already had serious underlying illnesses or were older have previously died of the novel corona virus. 


Symptoms of Covid-19 disease, which is caused by the coronavirus.

The range of symptoms of Covid-19 disease, which is triggered by the Sars-CoV-2 coronavirus, is large: it ranges from nonexistent symptoms to severe pneumonia, which can lead to death. Typical symptoms for Covid-19 are according to WHO (PDF):

  • FeverFatigue. Tiredness
  • Expectoration
  • Shortness of breath
  • Sore throat
  • muscle pain
  • Joint pain
  • chills
  • Nausea or vomiting
  • stuffy nose
  • diarrhea
  • Coughing up blood

List of typical symptoms for Coronavirus Sars-CoV-2 and disease Covid-19.
The list of typical symptoms of the WHO is based on 55,924 laboratory-confirmed cases of Covid-19 that were examined by February 20, 2020. While most patients complained of fever (87.9 percent) and about two-thirds also about dry cough (67.7 percent), only about a third of Covid-19 patients suffered from fatigue and tiredness (38.1 percent) or Ejection (33.4 percent).
18.6 percent of the patients examined had shortness of breath, throat scratching were described by 13.9 percent. Muscle or joint pain reported 14.8 percent of the patients, chills 11.4 percent of those affected. Five percent or less of the patients examined also experienced other symptoms of Covid-19: nausea 5.0 percent, nasal congestion 4.8 percent, diarrhea 3.7 percent, coughing up blood 0.9 percent.

There are now increasing reports that people suffering from Covid-19 have complained of a loss of smell and taste. Other symptoms that not associate with Covid-19 have also been uncommon. 

Coronavirus Sars-CoV-2 and Covid-19: How long does the incubation time last? 
The Robert Koch Institute and the World Health Organization (WHO) currently assume that the incubation time of the Coronavirus Sars-CoV-2 is up to 14 days.

Symptoms and Disease: How Does Covid-19 Disease Work?
The course of the disease in Covid-19 depends on the age of the patient and his other diseases. More serious causes and complications have so far been observed predominantly in older people - the WHO reports "people over 60 years". According to the WHO, the following previous illnesses can also lead to a worse course of Covid-19:

  • high blood pressure
  • diabetes
  • Cardiovascular diseases
  • chronic respiratory diseases
  • cancer

Coronavirus Sars-CoV-2 and Covid-19: symptoms in younger people milder. 

The course of Covid-19 is milder in younger, healthy people. Infections have so far been rare in children and adolescents. The WHO listed just 2.4 percent of children under the age of 19 among the 55,924 laboratory-confirmed cases that were examined. Of these children and adolescents, 2.5 percent had a “serious” illness, 0.2 percent were classified as “critical” cases. Across all age groups, about eighty percent of patients whose Covid-19 disease has been corroborated by the laboratory have a "mild to moderate" disease, according to the WHO. 13.8 percent have a "serious" illness, 6.1 percent are "critical". In addition, allergy sufferers in the corona crisis are considered a risk group.

How contagious is the novel coronavirus Sars-CoV-2?
How contagious the newly discovered coronavirus is cannot yet be precisely assessed. Chinese researchers assume that an infected person infects an average of 1.4 to 2.5 people - similar to Sars. However, the transmission rate is dependent on a large number of factors. A first study shows how long you are contagious when you are infected with the coronavirus.

How can you protect yourself from being infected with Covid-19? 

Since coronaviruses are transmitted by droplet or smear infection, the Robert Koch Institute recommends the following measures against infection with the Sars-CoV-2 coronavirus:

  • good hand hygiene: regular and thorough hand washing with soap
  • Cough and sneeze etiquette
  • Distance to the sick and possibly sick (approx. One and a half to two meters)flu wave. These measures are not only used to prevent the coronavirus, but also to prevent the flu (influenza) with which the coronavirus Sars-CoV-2 has something in common. 

Does a protective mask help against the Sars-CoV-2 and Covid-19 coronavirus?
Leopoldville Academy of Science published a statement on the effectiveness of protective masks and is clearly in favor of wearing them. "Because a large number of unrecognized people move around without symptoms in public space, mouth-nose protection protects other people." Virologist demands mouth protection for all Germans.

Is there a vaccine against the Sars-CoV-2 coronavirus? 

According to RKI, there is progress in the development of vaccines against coronaviruses. MERS-CoV vaccines in particular are therefore currently being tested in clinical studies. However, they are not yet available to the general public. According to media reports, a first vaccine candidate will be tested in a clinical trial in China from the end of April 2020. According to the RKI, when a vaccine against Sars-CoV-2 is available is "currently not foreseeable"

When does the doctor diagnose "Coronavirus Sars-CoV-2" or "Covid-19"? 

The Robert Koch Institute has published a case definition that doctors can use to determine which patients should undergo a laboratory test for the new coronavirus. So far, this has mainly happened for people who have had contact with a confirmed case and who have respiratory problems or for people with respiratory problems who have previously been in a risk area. If the corona virus is found, this must be reported to the health department.
