Summary
A novel coronavirus (2019-nCoV) outbreak, similar to SARS and MERS, presents flu-like symptoms and pneumonia. This review analyzes its epidemic potential and current treatment strategies for this zoonotic disease.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- A novel coronavirus (2019-nCoV) outbreak has emerged, sharing genomic similarities with SARS and MERS.
- These zoonotic viruses are transmitted from animals to humans, with bats as the suspected primary reservoir.
- The 2019-nCoV is spreading rapidly, declared a pandemic by the WHO, necessitating urgent understanding.
Purpose of the Study:
- To review the characteristics of the 2019-nCoV outbreak.
- To analyze the relationship between the reproduction number (R0) and infection rates.
- To summarize current knowledge on symptoms, transmission, and treatment.
Main Methods:
- Meta-analysis of available data.
- Review of scientific literature on coronaviruses (SARS, MERS, 2019-nCoV).
- Analysis of epidemiological data, including reproduction numbers.
Main Results:
- The 2019-nCoV exhibits similarities to SARS and MERS, with zoonotic origins.
- Many countries show a reproduction number (R0) greater than 1, indicating epidemic spread.
- Asymptomatic infections and evolving viral strains present significant challenges.
Conclusions:
- The 2019-nCoV is a significant global health threat requiring comprehensive management strategies.
- Understanding transmission dynamics and R0 is crucial for controlling the pandemic.
- Further research into vaccines and treatments is essential, especially for asymptomatic cases.

17.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

01:26Factors Affecting the Risk of Infection
13.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

01:18Factors Affecting Illness
4.8K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
