The guidance outlines infection prevention and control advice for healthcare providers assessing possible cases of WN-CoV. It should be used in conjunction with local policies.
The guidance on the PHE website will remain under review as further scientific information is published about WN-CoV.
Our chief microbiologist has put together a summary of the guidelines, along with our recommended products for surface disinfection and hand hygiene.
The recently identified Wuhan novel coronavirus (WN-CoV) belongs to a large family of viruses with some causing a less-severe disease, such as the common cold, and others causing a more-severe disease such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) coronaviruses.
Coronaviruses are mainly transmitted by large respiratory droplets and direct or indirect contact with infected secretions. They have also been detected in blood, faeces and urine and, under certain circumstances, airborne transmission is thought to have occurred from aerosolised respiratory secretions and faecal material.
Sensitivity to Disinfectants
Coronaviruses are enveloped viruses which means that they are sensitive to a wide range of disinfectants.
There is evidence for other coronaviruses of the potential for widespread contamination of patient rooms/environments, so effective cleaning and decontamination is vital.
Cleaning and decontamination should only be performed by staff trained in the use of the appropriate PPE and infection prevention and control procedures.
The advice from PHE is to follow cleaning with neutral detergent with a chlorine-based disinfectant, in the form of a solution at a minimum strength of 1,000ppm available chlorine.
The main patient isolation room should be cleaned at least once a day, and following aerosol generating procedures or other potential contamination.
There should be more frequent cleaning of commonly used hand-touched surfaces and of anteroom/lobby areas (at least twice per day).
Dedicated or disposable equipment must be used for environmental decontamination. Reusable equipment must be decontaminated after use with a chlorine-based disinfectant as described above.
Personal protective equipment (PPE) and good infection prevention and control precautions are effective at minimising risk but can never eliminate it.
This is essential before and after all patient contact, removal of protective clothing and decontamination of the environment.
Use soap and water to wash hands or an alcohol hand rub if hands are visibly clean.
Rings (other than a plain smooth band), wrist watches and wrist jewellery must not be worn by staff involved in patient care or cleaning and disinfection procedures.
Evans Surface Disinfectants
Chlor Tabs 1 tablet in 1 L of water gives 1,000 ppm available chlorine.
If a chlorine disinfectant is not suitable for a particular application Safe Zone Plus, which is a ready to use (RTU) virucidal disinfectant, may be used.
