As with most, if not all medical conditions, early detection and treatment is important.
China released the information to the worlds medical community quite early allowing for quick mobilisation of resources, awareness and prevention.
Initial source was from Huanan Seafood Market where initial patients were workers at the seafood market. The seafood market also housed live stock (animals)
Most at risk are:
- Aged 55 +
- People with low immune systems.
- People with pre existing conditions .
- Smokers – due to increased respiratory problems.
Early symptoms – characteristics:
Most patients have mild symptoms and good prognosis.
On admission, most patients had
- Fever or cough and
- A third of patients had shortness of breath.
Other symptoms included:
- Muscle ache.
- Chest pain.

Characteristics of 99 cases of 2019 novel coronavirus pneumonia in Wuhan, China: a descriptive study of ground zero.
This is a descriptive study on the epidemiology and clinical characteristics of the 2019-nCoV, including data on 99 patients who were transferred to Jinyintan Hospital from other hospitals across Wuhan. It presents the latest status of the 2019-nCoV infection in China and adds details on combined bacterial and fungal infections.
Below inset is an excerpt from The Lancet. It is an official medical review, but is summarised for easier reading by those not in the medical profession. It also cites the contributors.
The Lancet – 2019-nCoV infection
“The reduced susceptibility of females to viral infections could be attributed to the protection from X chromosome and sex hormones, which play an important role in innate and adaptive immunity.
Additionally, about half of patients infected by 2019-nCoV had chronic underlying diseases, mainly cardiovascular and cerebrovascular diseases and diabetes
For severe mixed infections, in addition to the virulence factors of pathogens, the host’s immune status is also one of the important factors.
▪️presence of comorbidity ( presence of one or more additional conditions co-occurring with a primary condition)
might be associated with increased mortality.
When populations with low immune function, such as:
▪️people with HIV infection,
▪️people with long-term use of immunosuppressive agents, and
are infected with 2019-nCoV, prompt administration of antibiotics to prevent infection and strengthening of immune support treatment might reduce complications and mortality.
Some patients progressed rapidly with ARDS and septic shock, which was eventually followed by multiple organ failure.Read more at The Lancet
Therefore, early identification and timely treatment of critical cases is of crucial importance.”

▪️ Analysis of the distribution, patterns and determinants.
A global collaboration.
This was a global collaboration with the initial results being released early by China to Thailand, USA, France and Australia.
The complete genomic structure allows scientists to replicate the virus and subsequently, work on a possible vaccine to one or more of the mutated viruses.
The genomic sequence of nCov has been shared by Chinese researchers on various sequence databases to the global medical community.
All samples had a common ancestor with up to 7 mutations. The initial human infection was in Nov-Dec with subsequent human to human transmission.
