The symptoms of COVID‑19 cak168app.babyak168app.ak168app.babyak168app.babybabyan 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 ak168app.clubak168app.clubak168app.clubak168app.clubak168app.clubak168app.clubdays after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] ks168app.siks168app.siteteks16ks168app.site8app.siteOf those who develop symptomsks168app.site 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 thaic88ks168app.siten 50% lung involvic88ement on imaging)ic88ic88, and 5% develop critical symptomsic88 (respiratory ic88failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms.

Some people continue to experience a range of effects (long ic88ic88COVID) for months or yeaic88ic88ic88rs after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]

COVID‑19 ic88ic88ic88ic88transmission occurs when infecic88ic88tious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proxlr88lr88lr88lr88imity, but small airborne particles containing the virus can remain suspended in the air and travel over longlr88lr88lr88lr88lr88er distances, particularly indoors. Transmission can also occur lr88when people touch lr88lr88lr88lr88lr88their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contalr88gious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]

Telr88sting methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[1lr887][18] transcription-mediatop88lr88ed ampop88lification,[17][18][1lr889] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]

Several COVID-19 vaccop88op88op88ines have been approved and distriop88buted in various countries, many of whisi88si88si88ch have initiated mass vaccination campaigns.
