Lessons learnt from the COVID-19 pandemic emphasize the importance of awareness and surveillance for zoonoses, emerging infectious diseases, and antimicrobial resistance. Metagenomics-based surveillance methods offer a promising solution for improving early detection of pathogens.
Lessons learnt from the COVID-19 pandemic include increased awareness of the potential for zoonoses and emerging infectious diseases that can adversely affect human health. Although emergent viruses are currently in the spotlight, we must not forget the ongoing toll of morbidity and mortality owing to antimicrobial resistance in bacterial pathogens and to vector-borne, foodborne and waterborne diseases. Population growth, planetary change, international travel and medical tourism all contribute to the increasing frequency of infectious disease outbreaks. Surveillance is therefore of crucial importance, but the diversity of microbial pathogens, coupled with resource-intensive methods, compromises our ability to scale-up such efforts. Innovative technologies that are both easy to use and able to simultaneously identify diverse microorganisms (viral, bacterial or fungal) with precision are necessary to enable informed public health decisions. Metagenomics-enabled surveillance methods offer the opportunity to improve detection of both known and yet-to-emerge pathogens. Metagenomics-based surveillance could transform global efforts to detect risks to human health within a One Health framework.

Sporadic outbreaks of healthcare-associated COVID-19 infection in a highly-vaccinated inpatient population during a community outbreak of the B.1.617.2 variant: The role of enhanced infection-prevention measures

Liang En Wee, Edwin Philip Conceicao, Jean Xiang-Ying Sim, May Kyawt Aung, Myat Oo Aung, Yang Yong, Shalvi Arora, Karrie Kwan-Ki Ko, Indumathi Venkatachalam

Summary: Sporadic clusters of COVID-19 infection occurred in a highly vaccinated health care workers and patient population, despite enhanced infection-prevention measures. The unvaccinated and immunocompromised individuals remain at risk and should receive enhanced surveillance.

Amplified parallel antigen rapid test for point-of-care salivary detection of SARS-CoV-2 with improved sensitivity

Danny Jian Hang Tng, Bryan Chu Yang Yin, Jing Cao, Kwan Ki Karrie Ko, Kenneth Choon Meng Goh, Delia Xue Wen Chua, Yong Zhang, Melvin Lee Kiang Chua, Jenny Guek Hong Low, Eng Eong Ooi, Khee Chee Soo

Summary: This study reports an Amplified Parallel ART (AP-ART) that can quickly detect the COVID-19 virus with high sensitivity, even when using non-fasted saliva samples. Compared to existing techniques, AP-ART achieved a lower limit of detection. This new method has the potential to be used for rapid testing in resource-limited settings and play a crucial role in early diagnosis.

Summary: This study reveals a previously unreported mutation in the N gene of SARS-CoV-2, which may render certain commercial tests unable to accurately detect the virus, highlighting the importance of real-time surveillance of viral variants.

Healthcare-associated multispecies outbreaks of OXA-48-positive carbapenemase-producing Enterobacteriaceae in a Singapore tertiary-care hospital

Indumathi Venkatachalam, Molly Kue Bien How, Karrie Kwan Ki Ko, Nurdyana Binte Abdul Rahman, Edwin Philip Conceicao, May Kyawt Aung, Myat Oo Aung, Yong Yang, Kwee Yuen Tan, Jean Xiang Ying Sim, Lai Chee Lee, Moi Lin Ling

Summary: This study describes OXA-48-like carbapenem-producing Enterobacteriaceae (CPE) outbreaks at Singapore General Hospital between 2018 and 2020 and identifies the risk factors associated with OXA-48 carriage in the 2020 outbreak. The results indicate that diarrhea, contact with OXA-48-carrying patients, and exposure to carbapenems or penicillin are independent risk factors for OXA-48 carriage. These outbreaks are likely related to favorable ecological conditions and selective pressure from antimicrobial use.

Linking sporadic hospital clusters during a community surge of the severe acute respiratory coronavirus virus 2 (SARS-CoV-2) B.1.617.2 delta variant: The utility of whole-genome sequencing

Summary: Despite rigorous surveillance and a highly vaccinated healthcare worker population, sporadic clusters of healthcare-associated COVID-19 occurred during a community surge of the Delta variant. Genomic analysis played a critical role in timely cluster detection and identifying linkages among healthcare workers moving between clinical areas and sharing common lunch areas.

Environmental contamination and evaluation of healthcare-associated SARS-CoV-2 transmission risk in temporary isolation wards during the COVID-19 pandemic

Liang En Wee, Shalvi Arora, Karrie Kwan-Ki Ko, Edwin Philip Conceicao, Kristen K. Coleman, Kwee Yuen Tan, Hatijah Binti Tohid, Qinnan Liu, Grace Li Teng Tung, Shawn Wee Jin See, Chayaporn Suphavilai, Moi Lin Ling, Indumathi Venkatachalam

Summary: This study investigated the contamination of environmental samples in temporary isolation wards converted from general wards or prefabricated containers, and utilized whole-genome sequencing to investigate cluster outbreaks. The results showed environmental contamination with SARS-CoV-2 in temporary isolation wards, mainly from the toilet area and smartphones used for patient communication. However, no healthcare-associated transmission was detected in temporary isolation wards during the entire pandemic period.

No evidence for a common blood microbiome based on a population study of 9,770 healthy humans

Cedric C. S. Tan, Karrie K. K. Ko, Hui Chen, Jianjun Liu, Marie Loh, Minghao Chia, Niranjan Nagarajan

Summary: A large-scale population study reveals that there is no consistent core blood microbiome in healthy individuals. While human blood is generally considered sterile, recent research suggests the presence of a blood microbiome in healthy people. After analyzing sequencing data from multiple cohorts, researchers identified 117 microbial species in the blood of 9,770 healthy individuals, primarily commensals associated with the gut, mouth, and genitourinary tract. However, no co-occurrence patterns or associations between host phenotypes and microbes were found, suggesting that the translocation of commensal microbes from other body sites into the bloodstream is transient and sporadic.

Detection of viable SARS-CoV-2 in deep respiratory specimens despite negative nasopharyngeal SARS-CoV-2 RT-PCR: Occult COVID-19 as an unsuspected cause of pulmonary infiltrates in immunocompromised patients

Liang En Wee, Jing Yuan Tan, Karrie Kwan-Ki Ko, Wei Yee Wan, Deborah Chooi Mun Lai, Lynette Lin Ean Oon, Alfonso Tan-Garcia, Joe Poh Sheng Yeong, Angela Maria Takano Pena, Tony Kiat Hon Lim, Edwin Philip Conceicao, Indumathi Venkatachalam, Limin Wijaya, Thuan Tong Tan

Summary: This study describes two cases of occult COVID-19 in immunocompromised patients who had previously received rituximab treatment. Lung imaging showed ground-glass infiltrates, but nasopharyngeal samples were negative for SARS-CoV-2, leading to initially ruling out COVID-19. However, bronchoalveolar lavage specimens confirmed the persistence of SARS-CoV-2 in lung parenchyma, and viral isolation and immunohistochemistry further supported ongoing viral persistence and replication.
