The COVID-19 portal

Coronavirus disease 2019 (COVID-19) is acontagious disease caused by thecoronavirusSARS-CoV-2. In January 2020, the disease spread worldwide, resulting in theCOVID-19 pandemic.

Transmission and life-cycle of SARS-CoV-2 causing COVID-19.

SeveralCOVID-19 vaccines have been approved and distributed in various countries, many of which have initiatedmass vaccination campaigns. Otherpreventive measures include physical orsocial 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. Whiledrugs have been developed to inhibit the virus, the primarytreatment is stillsymptomatic, managing the disease throughsupportive care,isolation, andexperimental measures.

The disease has continued to circulate since 2023. As of 2024, experts were uncertain as to whether it still qualified as a pandemic. Different definitions of pandemics lead to different determinations of when they end. As of 15 October 2025, COVID-19 has caused 7,101,788[1] confirmed deaths, and 18.2 to 33.5 million estimated deaths. The pandemic ranks as the fifth-deadliest pandemic or epidemic in history.

About the virus

SARS-CoV-2 as seen by a cryo-electron tomography scan.

SARS‑CoV‑2 belongs to the broad family of viruses known ascoronaviruses. It is apositive-sense single-stranded RNA (+ssRNA) virus, with a single linear RNA segment. Coronaviruses infect humans, other mammals, including livestock and companion animals, and avian species. Human coronaviruses can cause illnesses ranging from thecommon cold to more severe diseases such asMiddle East respiratory syndrome (MERS, fatality rate ~34%). SARS-CoV-2 is the seventh known coronavirus to infect people, after229E,NL63,OC43,HKU1,MERS-CoV, and the originalSARS-CoV.

Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenusSarbecovirus (beta-CoV lineage B). Coronaviruses undergo frequent recombination. The mechanism of recombination in unsegmented RNA viruses such as SARS-CoV-2 is generally by copy-choice replication, in which gene material switches from one RNA template molecule to another during replication. The SARS-CoV-2 RNA sequence is approximately 30,000bases in length, relatively long for a coronavirus—which in turn carry the largest genomes among all RNA families. Its genome consists nearly entirely of protein-coding sequences, a trait shared with other coronaviruses. (Full article)

About the symptoms

Symptoms of coronavirus disease 2019 (COVID-19)

Thesymptoms of COVID-19 are variable depending on thetype of variant contracted, ranging from mildsymptoms to a potentially fatal illness. Common symptoms includecoughing,fever,loss of smell andtaste, with less common ones includingheadaches,nasal congestion andrunny nose,muscle pain,sore throat,diarrhea,eye irritation, and toes swelling or turning purple, and in moderate to severe cases,breathing difficulties. People with theCOVID-19 infection may have different symptoms, and their symptoms may change over time. (Full article)

About the spread

COVID-19 is mainly transmitted from person to person through inhaling air contaminated bydroplets/aerosols and smallairborne particles containing the virus. Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing. Transmission is most likely at closer range but, can also occur can occur over longer distances, particularly indoors.

Infectious particles range in size fromaerosols that remain suspended in the air for long periods of time to largerdroplets that remain airborne briefly or fall to the ground. Additionally, COVID-19 research has redefined the traditional understanding of how respiratory viruses are transmitted. The largest droplets of respiratory fluid do not travel far, but can be inhaled or land on mucous membranes on the eyes, nose, or mouth to infect. Aerosols are highest in concentration when people are in close proximity, which leads to easier viral transmission when people are physically close, butairborne transmission can occur at longer distances, mainly in locations that are poorly ventilated; in those conditions small particles can remain suspended in the air for minutes to hours. (Full article)

Containment measures

Goals of mitigation include delaying and reducing peak burden on healthcare (flattening the curve) and lessening overall cases and health impact.
Many countries attempted to slow or stop the spread of COVID-19 by recommending, mandating or prohibiting behaviour changes, while others relied primarily on providing information. Measures ranged from public advisories to stringent lockdowns. Outbreak control strategies are divided into elimination and mitigation. Experts differentiate between"zero-COVID", which is an elimination strategy, andmitigation strategies that attempt to lessen the effects of the virus on society, but which still tolerate some level of transmission within the community. Containment strategies consists of the use of public health measures such ascontact tracing,mass testing,border quarantine,lockdowns andmitigation software.These strategies can be pursued sequentially or simultaneously during theacquired immunity phase through natural andvaccine-induced immunity.

Economic impact

TheCOVID-19 pandemic caused far-reaching economic consequences including theCOVID-19 recession, the second largest global recession in recent history, decreased business in the services sector during theCOVID-19 lockdowns, the2020 stock market crash (which included the largest single-weekstock market decline since the2008 financial crisis), theimpact of COVID-19 on financial markets, the2021–2023 global supply chain crisis, the2021–2023 inflation surge,shortages related to the COVID-19 pandemic including the2020–2023 global chip shortage,panic buying, andprice gouging. The pandemic led to governments providing an unprecedented amount ofstimulus, and was also a factor in the2021–2022 global energy crisis and2022–2023 food crises.

Amidst the recovery and containment, the world economic system was characterized as experiencing significant, broad uncertainty. Economic forecasts and consensus amongmacroeconomics experts show significant disagreement on the overall extent, long-term effects and projected recovery. Alarge general increase in prices was attributed to the pandemic. In part, therecord-high energy prices were driven by a global surge in demand as the world quit the economic recession caused by COVID-19, particularly due to strong energy demand in Asia.

Workplace

Hazard controls for COVID-19 in workplaces are the application ofoccupational safety and health methodologies forhazard controls to the prevention ofCOVID-19. Multiple layers of controls are recommended, including measures such asremote work andflextime,personal protective equipment (PPE) andface coverings,social distancing, and enhanced cleaning programs. Recently, engineering controls have been emphasized, particularly stressing the importance ofHVAC systems meeting a minimum of 5air changes per hour with ventilation orMERV-13 filters, as well as the installation ofUVGI systems in public areas.

Misinformation

False information, including intentionaldisinformation andconspiracy theories, about the scale of theCOVID-19 pandemic andthe origin, prevention, diagnosis, and treatment of the disease has beenspread through social media, text messaging, andmass media. False information has been propagated by celebrities, politicians, and other prominent public figures. Many countries have passed laws against "fake news", and thousands of people have been arrested for spreading COVID-19 misinformation. The spread ofCOVID-19 misinformation by governments has also been significant. (Full article)

Testing

COVID-19 testing involves analyzing samples to assess the current or past presence ofSARS-CoV-2, the virus that causesCOVID-19 and is responsible for theCOVID-19 pandemic. The two main types of tests detect either the presence of the virus orantibodies produced in response to infection. Molecular tests for viral presence through its molecular components are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks. Antibody tests (serology immunoassays) instead show whether someone once had the disease. They are less useful for diagnosing current infections because antibodies may not develop for weeks after infection. It is used to assess disease prevalence, which aids the estimation of theinfection fatality rate. (Full article)

Vaccine research

ACOVID‑19 vaccine is avaccine intended to provideacquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID‑19).

The COVID‑19 vaccines are widely credited for their role in reducing the spread of COVID‑19 and reducing the severity and death caused by COVID‑19. Many countries implemented phased distribution plans that prioritized those at highest risk of complications, such as the elderly, and those at high risk of exposure and transmission, such as healthcare workers. (Full article)

Drug research

COVID-19 drug development is the research process to develop preventative therapeuticprescription drugs that would alleviate the severity ofcoronavirus disease 2019 (COVID-19). From early 2020 through 2021, several hundreddrug companies,biotechnology firms, university research groups, and health organizations were developing therapeutic candidates for COVID-19 disease in various stages ofpreclinical orclinical research (506 total candidates in April 2021), with 419 potential COVID-19 drugs inclinical trials, as of April 2021. (Full article)

Long COVID

Long COVID orlong-haul COVID is a group ofhealth problems persisting or developing after an initial period ofCOVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. TheWorld Health Organization defines long COVID as starting three months after the initial COVID-19 infection, but other agencies define it as starting at four weeks after the initial infection.

Thecauses of long COVID are not yet fully understood.Hypotheses include lasting damage to organs and blood vessels, problems withblood clotting, neurological dysfunction, persistent virus or a reactivation of latent viruses andautoimmunity. Diagnosis of long COVID is based on (suspected or confirmed) COVID-19 infection or symptoms—and by excluding alternative diagnoses. (Full article)
