CHP investigates 118 additional confirmed cases of COVID-19
***********************************************************
Among the newly reported cases announced, five had travel history during the incubation period.
The CHP's epidemiological investigations and relevant contact tracing on the confirmed cases are ongoing. For case details and contact tracing information, please see the Annex or the list of buildings with confirmed cases of COVID-19 in the past 14 days and the latest local situation of COVID-19 available on the website "COVID-19 Thematic Website" (www.coronavirus.gov.hk).
Meanwhile, the Scientific Committee on Emerging and Zoonotic Diseases (SCEZD) under the CHP has reviewed the criteria for releasing confirmed coronavirus disease 2019 (COVID-19) patients from isolation and made updated recommendations based on the prevailing scientific understandings on COVID-19. The revised recommendations supersede the previous one dated July 6.
The updated criteria for releasing a confirmed COVID-19 patient from isolation are as follows:
For symptomatic patients:
1. Clinical conditions improve and afebrile; AND
2. Either one of the following laboratory criteria:
- With two clinical specimens of the same type (i.e. respiratory or stool) tested negative for nucleic acid of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse transcription polymerase chain reaction (RT-PCR) taken at least 24 hours apart. For patients ever with stool specimen(s) tested positive, they should have two negative stool specimens collected 24 hours apart before release from isolation; AND 10 days have passed since the onset of illness; OR
- Tested positive for SARS-CoV-2 antibody.
For patients who did not develop any COVID-19 compatible symptoms all along:
1. With two clinical specimens of the same type (i.e. respiratory or stool) tested negative for nucleic acid of SARS-CoV-2 by RT-PCR taken at least 24 hours apart. For patients ever with stool specimen(s) tested positive, they should have two negative stool specimens collected 24 hours apart before release from isolation; AND five days after the first positive RT-PCR test for SARS-CoV-2; OR
2. Tested positive for SARS-CoV-2 antibody.
In view of the severe epidemic situation, the CHP called on members of the public to avoid going out, having social contact and dining out. They should put on a surgical mask and maintain stringent hand hygiene when they need to go out. As a number of recent cases involve elderly people, the CHP strongly urged the elderly to stay home as far as possible and avoid going out. They should consider asking their family and friends to help with every day tasks such as shopping for basic necessities.
A spokesman for the CHP said, "Given that the situation of COVID-19 infection remains severe and that there is a continuous increase in the number of cases reported around the world, members of the public are strongly urged to avoid all non-essential travel outside Hong Kong.
"The CHP also strongly urges the public to maintain at all times strict personal and environmental hygiene, which is key to personal protection against infection and prevention of the spread of the disease in the community. On a personal level, members of the public should wear a surgical mask when having respiratory symptoms, taking public transport or staying in crowded places. They should also perform hand hygiene frequently, especially before touching the mouth, nose or eyes.
"As for household environmental hygiene, members of the public are advised to maintain drainage pipes properly, regularly pour water into drain outlets (U-traps) and cover all floor drain outlets when they are not in use. After using the toilet, they should put the toilet lid down before flushing to avoid spreading germs."
Moreover, the Government has launched the website "COVID-19 Thematic Website" (www.coronavirus.gov.hk) for announcing the latest updates on various news on COVID-19 infection and health advice to help the public understand the latest updates. Members of the public may also gain access to information via the COVID-19 WhatsApp Helpline launched by the Office of the Government Chief Information Officer. Simply by saving 9617 1823 in their phone contacts or clicking the link wa.me/85296171823?text=hi, they will be able to obtain information on COVID-19 as well as the "StayHomeSafe" mobile app and wristband via WhatsApp.
To prevent pneumonia and respiratory tract infection, members of the public should always maintain good personal and environmental hygiene. They are advised to:
• Wear a surgical mask when taking public transport or staying in crowded places. It is important to wear a mask properly, including performing hand hygiene before wearing and after removing a mask;
• Perform hand hygiene frequently, especially before touching the mouth, nose or eyes, after touching public installations such as handrails or doorknobs, or when hands are contaminated by respiratory secretions after coughing or sneezing;
• Maintain drainage pipes properly and regularly (about once a week) pour about half a litre of water into each drain outlet (U-trap) to ensure environmental hygiene;
• Cover all floor drain outlets when they are not in use;
• After using the toilet, put the toilet lid down before flushing to avoid spreading germs;
• Wash hands with liquid soap and water, and rub for at least 20 seconds. Then rinse with water and dry with a disposable paper towel. If hand washing facilities are not available, or when hands are not visibly soiled, performing hand hygiene with 70 to 80 per cent alcohol-based handrub is an effective alternative;
• Cover your mouth and nose with tissue paper when sneezing or coughing. Dispose of soiled tissues into a lidded rubbish bin, then wash hands thoroughly; and
• When having respiratory symptoms, wear a surgical mask, refrain from work or attending class at school, avoid going to crowded places and seek medical advice promptly.
