4. Travel and contact history matter: The NCDC’s window is 21 days. It covers travel to affected countries, contact with a confirmed or probable case, and contact with sick or dead animals or bushmeat.

5. Community warning signs: The NCDC says to be alert to fever that does not respond to treatment for the usual causes in the area, bleeding, bloody diarrhoea, bleeding into urine, or “any sudden or unexplained death.” Report such cases to a surveillance team or the nearest health facility.

HOW TO PROTECT YOURSELF

6. Wash your hands regularly: The NCDC urges regular hand hygiene with soap and water or an alcohol-based hand rub.

7. Avoid body fluids and the dead: The agency advised avoiding contact with the blood or body fluids of anyone who is ill, and with the body of anyone who died from an unknown illness.

8. Stay away from bushmeat and wild animals: The NCDC warned against handling sick or dead wild animals and against eating raw or poorly cooked bushmeat.

9. Seek medical help early and give the full story: The agency said anyone who falls ill, particularly after recent travel to an affected country or contact with a suspected or confirmed case, should seek prompt medical attention and give health workers accurate travel and exposure information. To report a suspected case, call the NCDC toll-free line, 6232, which operates 24 hours a day, seven days a week.

10. Stay calm and rely on official information: The NCDC urges Nigerians to rely on official public health authorities rather than unverified reports.
