Living With COVID And Returning To BAU!
Hurdles to Business As Usual – Hurdles to Life as Usual – Living with COVID!
Obstacles to re-open the country
As we come to the 2-month mark of lockdown, its effect on the populous is becoming apparent. The extreme restrictions have had a significant impact on people’s physical health, mental health, and general livelihood, and many people are itching for life to get back to normal. Many countries including New Zealand, Germany, Italy, and Spain have seen the first peak of COVID infections pass, and some have already begun reopening parts of their economy. This has led to concerns from public health officials that relaxing the lockdown too early and too liberally will lead to a rapid increase in infection rates. Indeed, Germany has already seen an increase in R0 above 1 (one infected person will infect more than one person, causing the disease to propagate).
Trying to work out how to reopen a country without causing another spike in COVID deaths is probably the biggest issue faced by public health officials across the world. And trying to convey clear instructions to the public is an issue some countries are currently struggling with. In the next few blogs we will look at the issues faced, what has worked and what needs improvement, and what we as the public can do to keep ourselves safe.
THE MASKS WE WEAR
We have discussed masks at the start of the pandemic, and we have discussed masks as the pandemic has progressed. Why are we bringing it up again?
Masks have been a heated point of contention, but their role in public health has matured over the past few weeks. At the beginning of the pandemic, masks were a rare commodity, with DIY stores running dry of masks, stories of people stealing masks from clinical environments, and very confusing advice on whether the public should wear masks in public.
At that time the WHO had recommended only infected patients and those working with infected people wear masks, to save on the precious PPE for medical professionals. N95 respirators are seen as the gold standard in protective equipment, and hospitals are still struggling to provide staff with enough respirators, let alone the public. Concerns have also been raised on whether using masks will provide a false sense of security, especially if they stop washing hands or touch the infected parts of the masks.
But now we are past the first COVID peak, and advice on masks has changed. People should wear a mask if they are in public. Germany has implemented this advice, as has Austria for its public markets. In the US many stores are requesting public wear masks before entry. Rather than surgical masks or respirators, the use of homemade or purchased cotton masks has been encouraged.
LET’S LOOK AT WHY
Surgical masks and respirators aim to protect the user from inhaling microscopic aerosolized COVID particles. Cotton masks do not function this way. Instead, they prevent the wearer from spreading COVID by catching much larger droplets that is coughed/sneezed or generally breathed out.
The majority of people with COVID-19 are able to spread the infection to others up to 3 days before they show symptoms. Indeed as many as 50% of infections seem to occur from pre-symptomatic individuals. During this time they produce the greatest amount of viral particles, and these particles can stay in the air for several hours. Someone with asymptomatic COVID walking around in public or in a shop could infect lots of people.
So wearing a mask, even if you are not symptomatic or around infected patients helps prevent the spread of the infection. We know already just how infective COVID-19 is, so any measures that reduces infection even a little will end up reducing spread drastically on a population level. It has been compared to seatbelts – one person might not feel the benefits, but they save thousands of lives across the country on a yearly basis.
IS THERE ANY EVIDENCE?
In our blogs, we often talk about the importance of evidence. We look at the quality of evidence, how different types of research gives good and bad evidence, and why we should always give evidence-based advice.
So is there any evidence supporting masks? We have evidence that cloth masks can stop 99% of droplets that are coughed up, and whilst it doesn’t block aerosols or actual viral particles it still has a significant impact on transmission. We also have strong evidence from high infectivity in choir groups and at call centers that the majority of transmission is via the air, rather than from surfaces.
But what about the highest level of evidence? Comparing people who do or don’t wear masks is not a study that can be easily performed or one that has been performed adequately. But why should you wait? There is minimal to no risk associated with wearing a cloth mask, it offers some protection to you and a lot of protection to the public. In these cases, we should take a precautionary approach.
We don’t have any high-quality evidence looking at hand washing or physical distancing. But precautionary measures enforced have helped reduce infectivity. The same applies to masks. The best we can offer is an Australian study looking at mask use during influenza. They found observational data suggest that transmission of viral respiratory infection was significantly reduced during the SARS epidemic with the use of face masks as well as other infection control measures” and “in an adjusted analysis of compliant subjects, masks as a group had protective efficacy in excess of 80% against clinical influenza-like illness.”. In compliant users, masks were highly efficacious.
So that’s our advice. If you're going to go out in public, wear a mask.
If you don’t have a mask, you can order one online. Or be adventurous. Make one out of an old T-shirt or sock. Here are some ways to make one without needing to sew.

Vitamin D Deficiency Symptoms: Signs Your Body May Be Lacking Vitamin D
Vitamin D is an essential nutrient that plays a vital role in maintaining strong bones, supporting the immune system and regulating several important functions in the body. Despite its importance, vitamin D deficiency is one of the most common nutritional deficiencies worldwide.
In India, vitamin D deficiency has become increasingly prevalent due to lifestyle factors such as limited sunlight exposure, indoor working environments and dietary habits. According to the Indian Council of Medical Research (ICMR), a significant percentage of the population may have insufficient vitamin D levels.
Recognizing the symptoms of vitamin D deficiency early is important because prolonged deficiency can lead to serious health complications affecting bones, muscles and overall wellbeing.
What Is Vitamin D and Why Is It Important?
Vitamin D is often called the “sunshine vitamin” because the body produces it when the skin is exposed to sunlight. It plays a key role in calcium absorption, which is essential for maintaining healthy bones and teeth.
In addition to bone health, vitamin D supports several important functions including:
immune system regulation
muscle function
inflammation control
hormonal balance
Low levels of vitamin D can disrupt these functions and contribute to various health problems.
Common Symptoms of Vitamin D Deficiency
Vitamin D deficiency can manifest through several symptoms, many of which are often overlooked or mistaken for other health issues.
Persistent Fatigue
Constant tiredness or low energy levels may be one of the earliest signs of vitamin D deficiency. Even after adequate rest, individuals with low vitamin D levels may continue to feel exhausted.
Vitamin D plays a role in cellular energy production, and insufficient levels may contribute to chronic fatigue.
Bone and Back Pain
One of the most well-known effects of vitamin D deficiency is bone discomfort. Vitamin D helps the body absorb calcium, which is essential for maintaining bone strength.
Low vitamin D levels may cause:
bone pain
lower back pain
increased risk of fractures
Persistent bone discomfort should be evaluated by a healthcare professional.
Muscle Weakness
Vitamin D is important for muscle health and function. Deficiency can lead to muscle weakness, cramps or general muscle fatigue.
Older adults with vitamin D deficiency may also experience reduced mobility and increased risk of falls.
Frequent Illness or Infections
Vitamin D plays a key role in supporting the immune system. Individuals with low vitamin D levels may experience frequent colds, infections or slower recovery from illness.
Research suggests that adequate vitamin D levels help strengthen immune defenses against respiratory infections.
Mood Changes and Depression
Vitamin D may influence brain function and mood regulation. Some studies have found a connection between low vitamin D levels and mood disorders such as depression or anxiety.
People experiencing persistent mood changes should consider evaluating vitamin levels as part of a broader health assessment.
Hair Loss
Severe vitamin D deficiency may contribute to hair thinning or hair loss. While hair loss can have multiple causes, nutritional deficiencies including vitamin D deficiency may play a role.
Slow Wound Healing
Vitamin D contributes to the body’s inflammatory response and tissue repair processes. Individuals with deficiency may notice slower wound healing or delayed recovery from injuries.
Who Is at Risk of Vitamin D Deficiency?
Several factors can increase the risk of vitamin D deficiency.
Limited Sun Exposure
People who spend most of their time indoors or use strong sun protection regularly may not receive enough sunlight to produce sufficient vitamin D.
Urban lifestyles and indoor work environments contribute to this problem.
Older Adults
As people age, the skin becomes less efficient at producing vitamin D from sunlight. Older adults may therefore require additional dietary intake or supplements.
Individuals with Darker Skin
Melanin reduces the skin’s ability to produce vitamin D from sunlight. Individuals with darker skin tones may require longer sun exposure to produce adequate levels.
Poor Dietary Intake
Few foods naturally contain vitamin D. Diets lacking fortified foods, dairy products or fatty fish may contribute to deficiency.
Medical Conditions
Certain medical conditions such as kidney disease, liver disease or digestive disorders can affect vitamin D absorption and metabolism.
How Is Vitamin D Deficiency Diagnosed?
Vitamin D deficiency is diagnosed through a simple blood test that measures the level of 25-hydroxyvitamin D in the bloodstream.
Doctors may recommend testing for individuals who experience symptoms of deficiency or belong to high-risk groups.
Early diagnosis allows healthcare providers to recommend appropriate treatment and lifestyle adjustments.
How to Improve Vitamin D Levels
Sunlight Exposure
Regular sunlight exposure is one of the most effective ways to increase vitamin D levels. Experts generally recommend 10 to 30 minutes of sunlight exposure several times per week, depending on skin type and location.
Dietary Sources of Vitamin D
Although limited, certain foods contain vitamin D, including:
fatty fish such as salmon and mackerel
egg yolks
fortified milk and cereals
mushrooms
Including these foods in the diet can help maintain healthy vitamin D levels.
Vitamin D Supplements
In cases of significant deficiency, doctors may recommend vitamin D supplements. The dosage depends on the individual’s vitamin levels, age and health status.
It is important to take supplements under medical supervision to avoid excessive intake.
Preventing Vitamin D Deficiency
Maintaining adequate vitamin D levels requires a balanced combination of sunlight exposure, proper nutrition and regular health monitoring.
Routine health checkups and vitamin testing can help identify deficiencies early and prevent complications.
Adopting a healthy lifestyle with balanced nutrition and outdoor activity can significantly improve vitamin D status and overall health.
Conclusion
Vitamin D deficiency is a common but often overlooked health concern. Symptoms such as fatigue, bone pain, muscle weakness and frequent infections may indicate low vitamin D levels.
Early detection and proper management are essential to prevent long-term health complications. By ensuring adequate sunlight exposure, maintaining a balanced diet and undergoing regular health checkups, individuals can support healthy vitamin D levels and improve overall wellbeing.
Recognizing the warning signs of vitamin D deficiency and seeking timely medical advice can help protect long-term health and maintain optimal body function.
