The Orange County Health Care Agency confirmed late Saturday night that the infected person’s virus was the same strain as the one that has spread to more than 2,000 people in 14 countries and territories and caused 56 deaths since it was discovered late last month in central China.
 
The patient is in good condition and is in isolation at a hospital, Orange County health officials said. Health authorities are following up with anyone who has had close contact with the patient, but also noted that people with casual contact — such as visiting the same grocery store or movie theater — “are at minimal risk of developing infection.”

3. Implementation of empiric additional
precautions for suspected nCoV infections
3.1 Contact and Droplet precautions for suspected
nCoV infection:
- In addition to Standard Precautions, all individuals,
including family members, visitors and HCWs
should apply Contact and Droplet precautions
- Place patients in adequately ventilated single rooms.
For naturally ventilated general ward rooms this is
considered to be 160 L/second/patient5;
- When single rooms are not available, cohort patients
suspected of nCoV infection together;
- Place patient beds at least 1m apart;
- Where possible, cohort HCWs to exclusively care
for cases to reduce the risk of spreading transmission
due to inadvertent infection control breaches;
- Use a medical mask (for specifications please see 2,6);
- Use eye/facial protection (i.e. goggles or a face
shield);
- Use a clean, non-sterile, long-sleeved fluid resistant
gown;
- Use gloves;
- Use either single use disposable equipment or
dedicated equipment (e.g. stethoscopes, blood
pressure cuffs and thermometers). If equipment
needs to be shared among patients, clean and
disinfect between each patient use (e.g. ethyl alcohol
70%);
- Refrain from touching eyes, nose or mouth with
potentially contaminated hands;
- Avoid the movement and transport of patients out of
the room or area unless medically necessary. Use
designated portable X-ray equipment and/or other
important diagnostic equipment. If transport is
required, use pre-determined transport routes to
minimize exposures to staff, other patients and
visitors and apply medical mask to patient;
- Ensure that HCWs who are transporting patients
wear appropriate PPE as described in this section
and perform hand hygiene;
- Notify the receiving area of necessary precautions as
soon as possible before the patient’s arrival;
- Routinely clean and disinfect patient-contact
surfaces;
- Limit the number of HCWs, family members and
visitors in contact with a patient with suspected
nCoV infection;
- Maintain a record of all persons entering the
patient’s room including all staff and visitors.
 

3.2 Airborne precautions for aerosol-generating
procedures for suspected nCoV infection:
Some aerosol generating procedures have been
associated with increased risk of transmission of
coronaviruses (SARS-CoV and MERS-CoV) such
as tracheal intubation, non-invasive ventilation,
tracheotomy, cardiopulmonary resuscitation,
manual ventilation before intubation and
bronchoscopy7,8.
Ensure that HCWs performing aerosol-generating
procedures:
- Use a particulate respirator at least as protective as a
NIOSH-certified N95, EU FFP2 or equivalent 2,6;
when putting on a disposable particulate respirator,
always perform the seal-check6. Note that if the
wearer has facial hear (beard) this can prevent a
proper respirator fit6.
- Eye protection (i.e. goggles or a face shield);
- Clean, non-sterile, long-sleeved gown and gloves;
- If gowns are not fluid resistant, use a waterproof
apron for procedures with expected high fluid
volumes that might penetrate the gown2;

Le maire de Wuhan a dit ce dimanche s'attendre à environ un millier de contaminations supplémentaires, sur la base du nombre de patients hospitalisés qui n'ont pas encore été testés.
 
Ce chiffre, s'il était confirmé, ferait bondir de moitié le nombre de contaminations annoncé dimanche pour l'ensemble du pays (2000 cas dont 56 mortels).
 
Lors d'une conférence de presse, le maire de Wuhan, Zhou Xianwang, a expliqué que les hôpitaux de la ville du centre de la Chine accueillaient plus de 2200 patients qui n'avaient pas encore pu effectuer un test de dépistage du nouveau coronavirus.
 
En se fondant sur un taux d'environ 45% de résultats positifs, «il est possible d'ajouter environ 1000 cas de contamination au nombre de patients qui ont déjà été hospitalisés», a-t-il expliqué, selon des propos rapportés par la télévision nationale.
 
L'agence Chine nouvelle a rapporté samedi que la ville de 11 millions d'habitants, placée de facto en quarantaine, comptait actuellement 4000 lits prévus pour accueillir des malades du coronavirus et aurait 6000 lits supplémentaires avant la fin du mois.
