What are the primary symptoms of COVID-19?
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.
“Subvariants of Omicron are more transmissible than their predecessors, & the risk of even more transmissible & more dangerous variants remains," said WHO Director-General Tedros Adhanom Ghebreyesus said during the weekly media briefing regarding COVID on Wednesday.3 days ago
Can you get COVID-19 twice?
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.
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
How long is the incubation period for COVID-19?
The time taken by the symptoms to first appear on an infected individual. The incubation time for COVID-19 ranges from 1-14 days, most commonly being around 5 days.
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
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
On September 1, 2022, Health Canada authorized the use of Moderna Spikevax Bivalent (50 mcg) COVID-19 vaccine as a booster dose in adults aged 18 years of age and older. This represents the first bivalent Omicron (BA.1)-containing mRNA COVID-19 vaccine authorized for use in Canada.3 days ago
Can asymptomatic people transmit COVID-19?
Yes, infected people can transmit the virus both when they have symptoms and when they don't have symptoms. This is why it is important that all people who are infected are identified by testing, isolated, and, depending on the severity of their disease, receive medical care.14-Jul-2020
In some people with COVID-19, symptoms persist for weeks or even months after recovering from the acute illness. This is referred to as ‘post-COVID-19 condition’, sometimes described as ‘long COVID’.25-Apr-2022
How does COVID-19 affect the lungs?
Covid 19 directly impacts the lungs and damages the alveoli (tiny air sacs).
Early research indicates that, compared to non-smokers, having a history of smoking may substantially increase the chance of adverse health outcomes for COVID-19 patients, including being admitted to intensive care, requiring mechanical ventilation and suffering severe health consequences.
Can people in quarantine eat fried foods?
WHO recommends limiting total fat intake to less than 30% of total energy intake, of which no more than 10% should come from saturated fat. To achieve this, opt for cooking methods that require less or no fat, such as steaming, grilling or sautéing instead of frying foods. If needed, use small amounts of unsaturated oils like rapeseed, olive or sunflower oil to cook foods. Prefer foods that contain healthy sources of unsaturated fats, such as fish and nuts.

Can COVID-19 be transmitted through food?
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
See full answerMasks should be used as part of a comprehensive strategy of measures to suppress transmission and save lives; the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19.If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. Check local advice where you live and work. Do it all!Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal of masks are essential to make them as effective as possible.
What is a silent carrier in the context of COVID-19?
There is recent evidence that COVID-19 can spread through silent carriers. These silent carriers or spreaders are people who are infected with coronavirus but show little or no symptoms of the disease. As a result, these people carry on with their daily lives, meeting family and friends, going to work, and spreading the disease without their own knowledge.
The “Three C's” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:• Crowded places;• Close-contact settings, especially where people have conversations very near each other;• Confined and enclosed spaces with poor ventilation.23-Dec-2021
What surfaces should be cleaned during the COVID-19 pandemic?
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
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
What can I do to prevent COVID-19 during grocery shopping?
• Clean your hands with sanitizer before entering the store.• Cover a cough or sneeze in your bent elbow or tissue.• Maintain at least a 1-metre distance from others, and if you can’t maintain this distance, wear a mask (many stores now require a mask).• Once home, wash your hands thoroughly and also after handling and storing your purchased products.14-Aug-2020
