Division of Public Health, Surveillance and Response

The Public Health Surveillance and Response Division was established incorporating GERMS-SA, Outbreak Response and Travel Health

The Division facilitates communication and data sharing between the national and provincial health departments and the NICD and provide epidemiological input to other NICD units through collaborative projects and support of surveillance and epidemiological activities and outbreak responses.

Working Groups:

  • GERMS-SA:  GERMS-SA is a laboratory-based surveillance programme for fungal and bacterial causes of pneumonia, meningitis and diarrhoeal diseases. Approximately 200 laboratories (public and private) report cases and send isolates to the NICD according to specific GERMS case definitions. At 25 sentinel sites across the country, surveillance officers collect clinical information from patients relating to these particular pathogens. The objectives of the programme are to:
    • Estimate the burden of infectious diseases under surveillance
    • Monitor antimicrobial susceptibility trends
    • Monitor the impact of the HIV/AIDS Comprehensive Care, Management and Treatment Programme in SA on HIV-associated opportunistic infections
    • Evaluate the effects of vaccines included in the Expanded Programme on Immunisation (EPI)
    • Monitor hospital-acquired infections

Individual studies currently being undertaken include a case-control study to measure the effectiveness of a conjugate vaccine against the invasive pneumococcal disease. The work carried out by the GERMS team has significantly contributed to the development of clinical guidelines for pneumonia, meningococcal disease, cholera, cryptococcosis, typhoid fever, etc., and the introduction of pneumococcal conjugate vaccine and Hib booster dose into the EPI. For more information and reports, access the GERMS-SA website.

  • Outbreak Response: The Outbreak Response Team is tasked with providing technical support for all aspects of communicable disease outbreak investigation and control in the nine provinces of South Africa, with particular emphasis on optimising the role of laboratory services during these events. The team aims to be a source of intelligence during outbreaks, and through working in close collaboration with the provincial and national Departments of Health, ensures a comprehensive outbreak response, as well as the development of systems for early detection and improved reporting. Through close partnerships with the NHLS diagnostic laboratories and reference units of the NICD, the team aims to facilitate appropriate laboratory diagnostic services during outbreaks and specialised diagnostics as required.

The Outbreak Response Team plays a crucial role in communications with stakeholders such as the Department of Health, medical practitioners, media and the general public. We publish a monthly Communicable Diseases Communiqué for providing up-to-date information on communicable disease events in South Africa, as well as regularly produce various healthcare worker guidelines, handbooks, fact-sheets, etc. for outbreak-prone communicable diseases of high public health importance. The Team also plays a central role in capacity development by providing in-service training to SA-FELTP residents, public health specialist registrars and secondees from international partner organisations, and routinely provides Epidemic Preparedness and Response Training to the staff of the Department of Health.

  • Travel Health: Travel Health was established in 2008 with the aim of being a centre for travel health-related activities and consulting on international health matters. This working group provides pre- and post-travel health advice and consultations for travel health practitioners, as well as for staff of the NHLS and NICD for work-related field activities. Regular expert consultations are provided, both locally and internationally to international focal points, institutes and health practitioners for South African travellers presenting with infectious diseases after travelling within southern Africa and further abroad. These include infections in travellers such as trypanosomiasis, severe malaria and rickettsial disease (tick bite fever). Consultation is also provided for the elimination of malaria in South Africa and other countries within southern Africa.


NICD has historically supported the National Department of Health (NDOH) in its roles of responding to priority diseases such as HIV and TB and to outbreaks of infectious diseases. Support to provincial DOH has primarily been from teams based at the NICD until 2014 when the NICD set up a provincial epidemiology team (PET) comprising 1 senior epidemiologist based at the NICD and 9 provincial field epidemiologists; one in each of the 9 provincial DOH offices.

Currently there are 5 provincial epidemiologists in KwaZulu-Natal, Mpumalanga, Free State, Eastern Cape and North West provinces. The process of filling the vacant positions is underway. Having an NICD epidemiologist in each province ensures that epidemiology, public health, diagnostic and clinical expertise within the NICD is available to provinces in a timely manner to effectively support communicable disease surveillance, prevention and control, epidemiology research, training and outbreak response at provincial and district level.

The main focus for the next few years is on HIV/TB and CDC (notifiable disease surveillance) and outbreak response. The PET provides expert technical advice and assistance on the design, maintenance, analysis and interpretation of surveillance databases. Additionally they support synthesis and analysis of surveillance and routine clinical and DHIS data collected at provincial, district and sub-district levels by both NICD and DoH to determine populations at risk, monitor disease trends and distribution, detect outbreaks and subsequently advise on interventions required to curb morbidity and address public health needs and resource allocation. To highlight one example;  provincial epidemiologists analyse data generated via the NICD centre for TB to describe and report on trends and numbers of patients diagnosed with drug susceptible and drug resistant TB. These reports analysed together with provincial data from electronic TB registers showing the actual number of patients’ initiating TB therapy, are used to identify and address gaps in the TB treatment cascade. The PET is also responsible for the implementation and management of the clinic based surveillance of HIV/TB drug resistance and STIs and provides some supervision to the GERMS surveillance.


The Communication Unit continues to expand its role in conveying important public health messages and outbreak alerts to both the medical and allied professionals through guidelines and information sheets, as well as to the general public. The NICD has over the past year set up a Twitter account, which is a useful tool for public health messaging.
