What are the known coronaviruses that can infect people?
Human coronaviruses are capable of causing illnesses ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS, fatality rate ~34%). SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV.
No long-term side effects of the vaccine are known. Government and healthcare institutions are monitoring the vaccine administration closely to keep track of any unexpected side effects of the vaccine. After the vaccine, your body will require some time (a few weeks) to build immunity against the virus.
How long does the virus that causes COVID-19 last on surfaces?
Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.07-Apr-2020
Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19.
What are coronaviruses?
See full answerCoronaviruses are a group of viruses belonging to the family of Coronaviridae, which infect both animals and humans. Human coronaviruses can cause mild disease similar to a common cold, while others cause more severe disease (such as MERS - Middle East Respiratory Syndrome and SARS – Severe Acute Respiratory Syndrome).A new coronavirus that previously has not been identified in humans emerged in Wuhan, China in December 2019. Signs and symptoms include respiratory symptoms and include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death.
Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can range from mild to lethal.
Which Omicron specific COVID-19 vaccine was approved by the UK?
The MHRA said the Spikevax vaccine met the standards of safety, quality and effectiveness. During trials, the vaccine triggered a strong immune response against both strains. In an analysis, the bivalent vaccine was also found to generate a good immune response against the omicron sub-variants BA.4 and BA.5.17-Aug-2022
The Covid 19 viral strain directly impacts the lungs, reducing its capacity and limiting the intake of oxygen and leading to ARDS and pneumonia. It is especially deadly in individuals who have underlying illnesses, and respiratory complications or both.
How was the COVID-19 vaccine developed so quickly?
See full answerDeveloping a vaccine generally involves years of research. First, we need a vaccine candidate that is evaluated in animals for its safety and efficacy. After a vaccine candidate passes a pre- clinical trial, it enters the clinical trial phase. While scientists have worked round the clock in the laboratory, even regulatory approvals which used to take several months have been fast tracked. It helped eliminate all the time lapses between the pre-clinical and clinical trial stages. Earlier, the vaccine development involved a series of steps, but in the case of the coronavirus vaccine, the scientists and regulators worked in tandem, accelerating the whole process without compromises on any protocols and any step.
High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.31-Mar-2022
How do I disinfect surfaces during the coronavirus disease pandemic?
In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection. Surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection.Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.31-Mar-2022
There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.14-Aug-2020
How long does loss of taste and smell last with COVID-19 ?
Most people who recover from COVID-19 find their sense of smell returns in a few weeks. But for others — up to 7%, according to one estimate1 — the loss can persist for months or even years.22-Jun-2022
Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually result in phlegm) and in a few cases loss in smell and taste. A few cases have also reported diarrhoea and fatigue.
How does COVID-19 affect the lungs?
Covid 19 directly impacts the lungs and damages the alveoli (tiny air sacs).
Covid 19 belongs to the coronavirus family, which also includes the SARS virus (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Symptoms) virus. The family of Coronavirus includes virus strains that cause the common cold and flu.
Where was the first case of the coronavirus disease observed?
The first human cases of COVID-19, the disease caused by the novel coronavirus causing COVID-19, subsequently named SARS-CoV-2 were first reported by officials in Wuhan City, China, in December 2019. Retrospective investigations by Chinese authorities have identified human cases with onset of symptoms in early December 2019. While some of the earliest known cases had a link to a wholesale food market in Wuhan, some did not.23-Apr-2020
The first known infections from SARS‐CoV‐2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
What is the origin of COVID-19?
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel severe acute respiratory syndrome coronavirus. It was first isolated from three people with pneumonia connected to the cluster of acute respiratory illness cases in Wuhan. All structural features of the novel SARS-CoV-2 virus particle occur in related coronaviruses in nature.
COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose or mouth, and, rarely, via contaminated surfaces.
Who issued the official name of COVID-19?
The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.
