COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic.
The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]
COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the virus can remain suspended in the air and travel over longer distances, particularly indoors. Transmission can also occur when people touch their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contagious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]
Testing methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[17][18] transcription-mediated amplification,[17][18][19] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]
Several COVID-19 vaccines have been approved and distributed in various countries, many of which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, use of face masks or coverings in public, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. While drugs have been developed to inhibit the virus, the primary treatment is still symptomatic, managing the disease through supportive care, isolation, and experimental measures.

Rwanda vs Nigeria: Chelle reignites the Super Eagles’ aspirations for the 2026 World Cup in Kigali.
On Friday, Eric Chelle became the inaugural non-Nigerian African coach to take the helm of the Super Eagles. The Malian coach directed his first match, resulting in a 2-0 win against Rwanda during a qualifying round for the 2026 World Cup. Chelle's appointment by the Nigeria Football Federation (NFF) took place on January 7, as he replaced Finidi George and succeeded interim coach Augustine Eguavoen. Since that time, he has dedicated three months to traveling across Nigeria, observing domestic league matches, and engaging with his players based in Europe. However, his initial team selection remained perplexing. Chelle opted for a highly offensive formation in Kigali, which appeared unbalanced on paper. Victor Osimhen, Samuel Chukwueze, Ademola Lookman, and Moses Simon were all included in the attacking lineup, while Alex Iwobi and Wilfred Ndidi occupied the midfield positions. "I had mixed feelings. […]
