Many of these are free and can be found on YouTube.

If you have no experience performing these exercises, be cautious and aware of your own limitations.Walk.

Even in small spaces, walking around or walking on the spot, can help you remain active.

If you have a call, stand or walk around your home while you speak, instead of sitting down.

If you decide to go outside to walk or exercise, be sure to maintain at least a 1-meter distance from other people.Stand up.

Reduce your sedentary time by standing up whenever possible.

Ideally, aim to interrupt sitting and reclining time every 30 minutes.

Consider setting up a standing desk by using a high table or stacking a pile of books or other materials, to continue working while standing.

Should you meet with other people during the COVID-19 pandemic?

In this difficult period it is best to meet virtually but if you have to meet others, do it carefully and with the right precautions.

Who is most at risk for COVID-19?

COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system.​

What is the most likely ecological reservoirs for coronavirus disease?

The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.

Can fans be used safely inside during the COVID-19 pandemic?

Air blowing from an infected person directly at another person in a closed space increases the risk of the virus spreading from one person to another.If COVID-19 is circulating in your community and the use of a table or pedestal fan is unavoidable, it is important to regularly bring in air from outside by opening windows or doors, while minimizing how much air blows from one person (or group of people) to another person (or group of people).

Under what conditions does COVID-19 spread easily?

Any situation in which people are in close proximity to one another for long periods of time increases the risk of transmission. Indoor locations, especially settings where there is poor or no ventilation, are riskier than outdoor locations.Transmission can occur more easily in the “Three C’s”:• Crowded places with many people nearby;• Close-contact settings, especially where people have conversations very near each other;• Confined and enclosed spaces with poor ventilation. The risk of COVID-19 spreading is higher in places where these “3Cs” overlap.

Can the coronavirus disease spread through feces?

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.

What is the incubation period of the coronavirus disease?

The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.

Are Vaccine Side Effects a good sign?

Experiencing side effects isn’t necessarily a bad thing. In fact, it’s a sign your body is responding. “The good news on our part is that a brisk response equals an effective response,” Dr. Mark Loafman, chair of family and community medicine for Cook County Health in Illinois, told NBC 5.

Can COVID-19 spread in hot and humid climates?

See full answerFrom the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days.

Can the coronavirus disease be transmitted through water?

Drinking water is not transmitting COVID-19. And, if you swim in a swimming pool or in a pond, you cannot get COVID-19 through water. But what can happen, if you go to a swimming pool, which is crowded and if you are close to other the people and if someone is infected, then you can be of course affected.

What are foods to avoid during the COVID-19 pandemic?

See full answerReduce foods such as red and fatty meats, butter and full-fat dairy products, palm oil, coconut oil, solid shortening and lard. Avoid trans fats as much as possible. Read nutrition labels to ensure that partially hydrogenated oils are not listed in the ingredients. If food labels are not available, avoid foods which commonly contain trans fats such as processed and fried foods, like doughnuts and baked goods – including biscuits, pie crusts, frozen pizzas, cookies, crackers and margarines that include partially hydrogenated fat.If in doubt, minimally processed foods and ingredients are better choices. Consume enough fibre Fibre contributes to a healthy digestive system and offers a prolonged feeling of fullness, which helps prevent overeating.

Will climate change make COVID-19 worse?

There is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.

What are the chances of getting Covid-19 after vaccine?

It showed that there were nine cases of COVID-19 at least seven days after the second dose among 19,965 vaccine recipients and 169 among 20,172 placebo recipients. “Bottom line is that it is rare to get the disease after vaccination but not impossible,” said Professor Tambyah.

Do COVID-19 and tuberculosis spread in the same way?

See full answerTB bacilli remain suspended in the air in droplet nuclei for several hours after a TB patient coughs, sneezes, shouts, or sings, and people who inhale them can get infected. The size of these droplet nuclei is a key factor determining their infectiousness. Their concentration decreases with ventilation and exposure to direct sunlight.COVID-19 transmission has primarily been attributed to the direct breathing of droplets expelled by someone with COVID-19 (people may be infectious before clinical features become apparent). Droplets produced by coughing, sneezing, exhaling and speaking may land on objects and surfaces, and contacts can get infected with COVID-19 by touching them and then touching their eyes, nose or mouth . Handwashing, in addition to respiratory precautions, are thus important in the control of COVID-19.

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.

What does pre-symptomatic transmission of COVID-19 mean?

The incubation period for COVID-19, which is the time between exposure to the virus (becoming infected) and symptom onset, is on average 5-6 days, however can be up to 14 days. During this period, also known as the “pre- symptomatic” period, some infected persons can be contagious. Therefore, transmission from a pre-symptomatic case can occur before symptom onset.

Is ventilation an important factor in preventing COVID-19 from spreading?

See full answerVentilation is an important factor in preventing the virus that causes COVID-19 from spreading. Recirculated air from split air conditioning units, fan coils or any system that runs with a recirculation mode should be avoided where possible, unless in a single occupancy room with no one else present. If recirculation is unavoidable, increase outdoor air exchange by opening windows, if possible and safe to do so, and minimize air blowing from one person directly at another.Floor or ceiling fans can provide ventilation when the people occupying the room are from the same household, but are not recommended when travelers from different households are together.

Fabric masks are recommended to prevent onward transmission in the general population in public areas, particularly where distancing is not possible, and in areas of community transmission. This could include the school grounds in some situations. Masks may help to protect others, because wearers may be infected before symptoms of illness appear. The policy on wearing a mask or face covering should be in line with national or local guidelines. Where used, masks should be worn, cared for and disposed of properly.

Are smokers more vulnerable to contracting COVID-19?

Tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

Why is COVID-19 causing so much stigma?

The level of stigma associated with COVID-19 is based on three main factors: 1) it is a disease that’s new and for which there are still many unknowns; 2) we are often afraid of the unknown; and 3) it is easy to associate that fear with ‘others’. It is understandable that there is confusion, anxiety, and fear among the public. Unfortunately, these factors are also fueling harmful stereotypes.
