PUIs excluded Update on testing 1. Despite the expanded testing criteria the lab turn-around times have been maintained. We will monitor the turn-around times carefully in order to determine the impact of the expanded testing criteria. 2. Antigen testing is now available at Cape Town International Airport for travellers who arrived without having a COVID test. 3. Antigen testing will also be used to monitor specific outbreaks. 4. The testing and surveillance team are continuously reviewing the testing criteria and will advise should further revisions be required.

Garden Route: increase in cases across all the subdistricts excluding Kannaland. Main subdistricts of concern are George, Knysna and Bitou. Areas of concern in George remain Thembalethu, Pacaltsdorp and the Conville area. In Knysna, cases are widespread. Areas of concern include the town of Knysna and Hornley. Cases in Bitou are also widespread, with Kwanokuthula the main area of concern. Test positivity rates of up to 32% noted. 10 November 2020 Nothing specific to report in Mossel Bay/Oudtshoorn/Hessequa . 2. Planned actions include going out as a collective (EHOs, SAPS, law enforcement, Health); working with the municipalities; SMSs; social media messaging. A district huddle is Surveillance starting tomorrow. Huddle 3. West Coast: Numbers low; Matzikama stabilising; no clusters detected in Bergrivier. 4. Overberg: No clusters across the district. Cases in Theewaterskloof are across all towns. Outbreak in school near Villiersdorp under control 5. Cape Winelands: no clusters detected. Vigilance re students in Stellenbosch remains. Additional points: 1. Increase in cases 7 days vs. previous 7 days; largely due to increases in the rural districts. 2. Nothing new to report from any of the Metro substructures 3. Concern remains regarding lack of adherence to NPIs, COVID fatigue, non-disclosure etc. 4. Holiday makers (intra- and inter-provincial travel) will remain a concern for COVID-19 spread, nationally, especially with the festive season approaching (and possible implications for the healthcare platform when WC resident holiday makers return to the province).

This may continue upwards indicating an increase in cases. At sub-district level, Khayelitsha is showing an increase in cases. We will have to watch this closely over the next few days. Rural is showing an increase in the 7 day moving average of cases. This is driven by George, which continues to show a sharp increase in the 7 and 14 day moving averages of new cases. The Overberg appears to be stabilizing after an outbreak, but the 7 day moving average is pointing upwards, and will have to be watched closely.
