Highlight of the Week COVID-19: Safe Re-opening of NYSC Orientation Camp in Nigeria

The National Youth Service Corps (NYSC) is an initiative of the Federal Government of Nigeria through which

graduates of tertiary institutions across the country are required to complete a mandatory one-year of

service to the nation. As part of this process, graduates are deployed across all 36 states and the Federal

Capital Territory and required to spend three weeks in an orientation camp in their state of deployment.

Due to the COVID-19 pandemic, this year, the NYSC orientation calendar was delayed to prevent further

transmission of the disease. However, following the resumption of most socio-economic, political and

educational activities across the country, the Nigeria Centre for Disease Control (NCDC) has been working

closely with NYSC authorities to ensure the safe reopening of orientation camps for prospective Corps

Members and NYSC community such as staff, traders, security etc.

The main objective of this is to strengthen infection prevention control in NYSC camps and promptly identify

outbreaks of COVID-19 in camps for treatment. This will involve the use of rapid diagnostic tests (RDTs),

approved for use in specific settings by WHO, to screen members of every NYSC orientation camp community

as resumption commences 10th of November, 2020.

NCDC in collaboration with the Presidential Task Force on CIVID-19 and NYSC, has also developed and

published a National Guidelines on 2020 National Youth Service Corps (NYSC) Orientation Camp activities

detailing critical information to guide corps members during their service year on reducing the risk of

infection. Readiness assessments have been conducted across NYSC camps to ensure that all camps meet

the key performance indicators (KPIs) of COVID-19 preventive measures and are ready for safe opening. In

addition, a joint NCDC and NYSC webinar was held with corps members and a media chat with members of

the press, to sensitise the public on efforts to ensure the safe reopening of NYSC orientation camps in the

context of COVID-19.

We urge State NYSC officials, State Ministries of Health and other relevant stakeholders to take ownership

of all COVID-19 related operations and activities across the NYSC camps in their respective states.

Importantly, corps members and other NYSC community members are strongly advised to take responsibility

by ensuring strict compliance with all recommended COVID-19 prevention and control measures.
