Coronavirus disease 2019

Coronavirus disease 2019

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.

2. The Science of Patterns: How Our Brains Detect and Use Repetition

Human cognition is remarkably adept at recognizing patterns, a trait rooted in the brain’s neural architecture. Cognitive processes such as visual perception and memory rely heavily on detecting regularities in data. For example, our visual cortex filters repetitive shapes and colors, enabling us to quickly identify familiar objects or predict upcoming events.

This ability conferred evolutionary advantages; early humans who recognized patterns in animal behavior or environmental cues could better anticipate threats or resources. Today, pattern recognition remains essential in tasks like language understanding, navigation, and even social interactions. Psychologically, predictable patterns produce comfort and reduce uncertainty, while unexpected patterns can evoke excitement, as seen in suspenseful storytelling or dynamic gameplay.

3. Patterns in Nature and Ancient Art: Foundations of Human Understanding

Nature abounds with patterns—fractals in snowflakes, symmetry in leaves, and repetitive motifs in animal markings. Ecosystems often display fractal structures, which can be described mathematically and are thought to optimize resource distribution. These natural patterns served as early models for humans, inspiring primitive art and cultural expressions.

Ancient civilizations embedded patterns into textiles, mosaics, and carvings, often emphasizing symmetry and repetition. Notably, the use of rare and costly dyes, such as purple derived from the murex snail, elevated the importance of certain patterns and colors. Purple dye’s expense made it a symbol of royalty and power, emphasizing the cultural significance of patterning in social hierarchies.

4. Kaleidoscopes and Optical Patterns: The Intersection of Art and Perception

Kaleidoscopes use mirrors and colored fragments to produce intricate geometric patterns, captivating viewers with ever-changing symmetrical designs. These devices exploit basic geometric principles—reflection, symmetry, and repetition—to create visually mesmerizing effects.
