nCoV , kiinasta Wuhanista lähtenyt uusi SARS virus tarttuu nopeasti ihmisestä toiseen ja letaalius on huomattava..

 ei ole vielä tietystikään  mitään tietoa, kehittyisikö   vasta-aineita tai olisiko  rokotteen sijaa.
ja tyrehtyisikö moinen itsestään...
 Toistaiseksi tähän  virukseen jo kuollaan ja se on uusi ihmiskunnassa, siis pandemiapotentiaalinen.
Viikonloppuna sairastuneiksi ilmoitetaan toistasataa, tosin arvioidaan että se käytännössä on lähes 2000 tapausta8 1700  nurkilla) . Hesari kirjoittaa.  Koska Wuhan- New Yörk liikenne on  suurta,  globaalille leviämiselle on  hyvät edellytykset.

 Taitaa alkaa taas samantapainen profylaksia kuin edellisessä pahassa SARS- purkauksessa.  Sitähän on paljon  Coronaviruksia, jotka eivät ole  vaarallisia. tai aiheutavat vain lievää  oiretta, josta parannutaan.
Täytyy taas katsoa uutta tietoa, mitä tässä on tapahtunut. Tokko muuten mitään erityistä löytyy, muuta kuin profylaksianeuvoja.
PubMed Hakusana "Novel CoV". Saan 11 pääjuurta tähän puuhun.  Tällä hakusanalla tulee vanhat pahat esiin myös koska ne olivat aikoinaan myös uusia.  Tämän erityisnimi  on esim 2019-nCoV. Wordpress blogiin asetan tuon ensimmäisen artikkelin linkin.

Respiratory tract viral infection caused by viruses or bacteria is one of the most common diseases in human worldwide, while those caused by emerging viruses, such as the novel coronavirus, 2019-nCoV that caused the pneumonia outbreak in Wuhan, China most recently, have posed great threats to global public health. Identification of the causative viral pathogens of respiratory tract viral infections is important to select an appropriate treatment, save people's lives, stop the epidemics, and avoid unnecessary use of antibiotics. Conventional diagnostic tests, such as the assays for rapid detection of antiviral antibodies or viral antigens, are widely used in many clinical laboratories. With the development of modern technologies, new diagnostic strategies, including multiplex nucleic acid amplification and microarray-based assays, are emerging. This review summarizes currently available and novel emerging diagnostic methods for the detection of common respiratory viruses, such as influenza virus, human respiratory syncytial virus (RSV), coronavirus, human adenovirus (hAdV), and human rhinovirus (hRV). Multiplex assays for simultaneous detection of multiple respiratory viruses are also described. It is anticipated that such data will assist researchers and clinicians to develop appropriate diagnostic strategies for timely and effective detection of respiratory virus infections.

Human coronaviruses (hCoV) usually cause mild to moderate upper respiratory tract illnesses. The novel coronavirus (nCoV), or Middle East respiratory syndrome coronavirus (MERS-CoV), is a particular strain different from any other known hCoV with the possibility of human and also zoonotic transmissions. The aim of the study to assess primary health care (PHC) physicians' knowledge and adherence regarding Saudi Ministry of Health guidelines regarding MERS-CoV.

Novel coronavirus (nCoV) belongs to the Coronaviridae family, which includes the virus that causes SARS, or severe acute respiratory syndrome. However, infection source, transmission route, and host of nCoV have not yet been thoroughly characterized. In some cases, nCoV presented a limited person-to-person transmission. Therefore, early diagnosis of nCoV may be of importance for reducing the spread of disease in public. Methods for nCoV diagnosis involve smear dyeing inspection, culture identification, and real-time PCR detection, all of which are proved highly effective. Here, we performed a meta-analysis to evaluate the effectiveness of real-time PCR for diagnosing nCoV infection...we propose real-time PCR as an efficient method that offers an auxiliary support for future nCoV diagnosis.Free Article

A novel coronavirus, MERS-CoV (NCoV, HCoV-EMC/2012), originating from the Middle-East, has been discovered. Incoming data reveal that the virus is highly virulent to humans. A model that categorizes coronaviuses according to the hardness of their shells was developed before the discovery of MERS-CoV. Using protein intrinsic disorder prediction, coronaviruses were categorized into three groups that can be linked to the levels of oral-fecal and respiratory transmission regardless of genetic proximity. Using this model, MERS-CoV is placed into disorder group C, which consists of coronaviruses that have relatively hard inner and outer shells. The members of this group are likely to persist in the environment for a longer period of time and possess the highest oral-fecal components but relatively low respiratory transmission components. Oral-urine and saliva transmission are also highly possible since both require harder protective shells. Results show that disorder prediction can be used as a tool that suggests clues to look for in further epidemiological investigations.Free PMC Article  ( Sisältää kuvan struktuurista)

East Mediterr Health J. 2013;19 Suppl 1:S48-54. Review. Mass gatherings are attended by an increasingly global audience and thus raise the concern of possible acute public health risks not normally encountered by the host population. The potential acute risks to individual and population health include communicable diseases. The communicable disease risks include emerging and re-emerging diseases in host and visiting populations. In this review, we provide an overview ofthe literature on respiratory infections at mass gatherings, then describe the impact of novel coronavirus 2012 (nCoV), an emerging respiratory disease virus, on the preparations for mass gathering. Although, nCoV emerged prior to the 2012 Hajj pilgrimage season, Muslims completed their religious duty without acquiring infections by nCoV. Clearly, the global nature of mass gatherings and their potential risks to international health make it imperative that research on such events and guidelines produced for their management are relevant to diverse contexts and are a collaborative effort between global experts.

In April 2012, an outbreak of acute respiratory illness occurred in a public hospital in Zarqa city, in Jordan; 8 health care workers were among the 11 people affected, 1 of who later died. The cause of the outbreak was unknown at the time and an epidemiological investigation including laboratory testing carried out immediately afterthe outbreak was inconclusive. Following the discovery of novel coronavirus infection (nCoV) in the Arabian peninsula in September 2012, stored respiratory and serum samples of patients from this outbreak were retested and the diagnosis of nCoV was confirmed in 2 deceased patients. This paper describes the epidemiological findings of retrospective investigation carried out in November 2012 and highlights the likelihood of nosocomial transmission of nCoV infection in a health-care setting. A total of 2 laboratory-confirmed and 11 probable cases were identified from this outbreak of whom 10 were HCWs and 2 were family members of cases.Free Article

In February 2013, novel coronavirus (nCoV) infection was diagnosed in an adult male in the United Kingdom with severe respiratory illness, who had travelled to Pakistan and Saudi Arabia 10 days before symptom onset. Contact tracing identified two secondary cases among family members without recent travel: one developed severe respiratory illness and died, the other an influenza-like illness. No other severe cases were identified or nCoV detected in respiratory samples among 135 contacts followed for 10 days.Free Article

Euro Surveill. 2013 Feb 21;18(8). pii: 20406.On 24 October 2012, a patient with acute respiratory distress syndrome of unknown origin and symptom onset on 5 October was transferred from Qatar to a specialist lung clinic in Germany. Late diagnosis on 20 November of an infection with the novel Coronavirus (NCoV) resulted in potential exposure of a considerable number of healthcare workers. Using a questionnaire we asked 123 identified contacts (120 hospital and three out-of-hospital contacts) about exposure to the patient. Eighty-five contacts provided blood for a serological test using a two-stage approach with an initial immunofluorescence assay as screening test, followed by recombinant immunofluorescence assays and a NCoV-specific serum neutralisation test. Of 123 identified contacts nine had performed aerosol-generating procedures within the third or fourth week of illness, using personal protective equipment rarely or never, and two of these developed acute respiratory illness. Serology was negative for all nine. Further 76 hospital contacts also tested negative, including two sera initially reactive in the screening test. The contact investigation ruled out transmission to contacts after illness day 20. Our two-stage approach for serological testing may be used as a template for similar situations.
