Bats appear to be the source of the coronavirus, but it’s unclear which type of animal was the “intermediate host” that passed the virus on to human beings.

How it’s transmitted

COVID-19 is sent by means of “close vulnerable contact.” The report said air-borne spread “is not thought to be a major driver of transmission.”

Human-to-human spread in China “is mostly happening in households,” the report said, including that 78%to 85%of “clusters” of coronavirus cases remained in households.

No resistance

The coronavirus “is a freshly identified pathogen,” and “there is no known pre-existing resistance in people,” the report stated.

” Everybody is assumed to be prone, although there may be risk elements increasing susceptibility to infection,” it said.

The report said people the researchers spoke with “could not remember” circumstances where a kid sent the infection to a grownup.

Types of signs

COVID-19 signs can range from no symptoms “to extreme pneumonia and death.” Mild respiratory issues and fever start, usually, 5 to six days after infection, the report stated.

In over 55,000 cases studied, signs included:

• Fever (879%)
• Dry cough (677%)
• Tiredness (381%)
• Production of sputum, saliva and mucus from the breathing system (334%)
• Shortness of breath (186%)
• Sore throat (139%)
• Headache (136%)
• Chills (114%)

Seriousness

About 80%of verified patients had moderate to moderate cases of COVID-19, 13.8%had serious cases, and 6.1%were vital, with breathing failure and multiple organ failure.

Pre-existing conditions and age impact COVID-19’s intensity.

People over 60 years of ages and individuals “with underlying conditions such as high blood pressure, diabetes, heart disease, persistent respiratory illness and cancer” are at a higher danger of ending up being seriously or fatally ill from COVID-19

In children, the illness “seems relatively rare and mild.” Just 2.5%of cases in kids were severe, and 0.2%were critical.
