Background

SARS-CoV-2 has globally increased morbidity and mortality rates. England witnessed a massive surge in hospitalizations and deaths after SARS-CoV-2 Alpha emerged.

Consequently, a national lockdown was imposed in January 2021 to curb social contact, with the concurrent implementation of a mass vaccination program.

As a result, coronavirus disease 2019 (COVID-19) cases, hospitalizations, and deaths declined sharply in early 2021. Restrictions were gradually eased after March 2021, and the pandemic re-entered a growth phase with the emergence of the SARS-CoV-2 Delta in April 2021.

All domestic restrictions were removed in July 2021, with society reopening to an extent unseen since the start of the pandemic.

Restrictions were not since re-introduced at a large scale, even when the prevalence was high late in 2021 and during the Omicron waves.

Evaluating the trends between infection levels and hospitalization rates can help inform public health agencies and governments to implement proportionate and appropriate restrictions. When IHR and IFR are accurate, severe outcomes could be forecast over the short term.

The study and findings

In the present study, researchers explored the dynamics of SARS-CoV-2 IHR and IFR in England over 23 months. They used data from the real-time assessment of community transmission (REACT)-1 study that conducted 19 cycles of surveys from May 2020 to March 2022. Persons aged five or older were contacted for participation and sent a self-administered swab test.

Data on COVID-19 cases, hospitalizations, deaths, and vaccinations were accessed from an official government website. The time lag from swab positivity to the occurrence of severe outcomes declined throughout the study.

There was a time lag of 19 days to hospitalization and 26 days to death during REACT-1 cycles 1-7 (May 1 to December 3, 2020).

During cycles 14-19 (September 9, 2021, to March 31, 2022), time lags were shorter at seven days to hospitalization and 18 days to death. Contrastingly, time lags were extremely long during cycles 8-13 (December 30, 2020, to July 12, 2021) at 24 days to hospitalization and 40 days to death. The IHR and IFR were estimated to be 2.6% and 0.67%, respectively, during cycles 1-7.

IHR was 0.76%, and IFR was 0.09% during cycles 14-19. The IHR and IFR were far lower for participants aged 64 or younger than those aged 65 or above during cycles 1-7 and 14-19.

The team compared the average IFRs and IHRs over four-week intervals to a baseline period (May 1 to November 11, 2020).

The average IFR was 1.68 and 1.31 times greater than the baseline in late November 2020 and January 2021, when SARS-CoV-2 Alpha accounted for 15% and 86% of cases, respectively. The average IHR and IFR reduced to 0.51 and 0.25 of baseline in April 2021, when 47% of the population had received at least one vaccine dose.

The average IHR and IFR were 0.84 and 0.43 of baseline in June-July 2021, respectively, when the Delta variant accounted for 99% of infections and 50% of the population had been double vaccinated.

IHR and IFR showed a steady decline from September 2021 and were sharply reduced in December 2021, when the proportion of booster vaccine recipients increased.

The mean IHR was 0.62%, and the average IFR was 0.06% by March 2022, when the Omicron variant caused over 99% of cases. The time lag between swab positivity and daily case numbers varied throughout the study and was three days, -7 days, and one day during cycles 1-7, 8-13, and 14-19, respectively.

The case ascertainment rate, defined as the proportion of cases identified with a positive test through mass testing, was 36.1% overall and varied throughout the study.

It increased from around 20% in July 2020 to 30% during August-December 2020, with a sharp surge between May and July 2021 and a steep decline between December 2021 and March 2022.

Conclusions

The researchers illustrated the temporal relationship between community prevalence of SARS-CoV-2 infection and severe outcomes.

They estimated SARS-CoV-2 IHR, IFR, and case ascertainment rates by assessing the differences in the swab positivity estimates and the time lag of COVID-19 cases, hospitalizations, and deaths.

The findings revealed a decline in SARS-CoV-2 infection severity over time in England. Community-based studies like REACT-1 can provide unbiased temporal estimates of infection levels, allowing for rapid detection of IHR or IFR changes.

Appropriate interventions can be implemented with early warnings when they are highly effective.

8 Tips for Incorporating More Fruits into Your Dessert

Published

 on

Incorporating more fruits into your desserts is not just a way to enhance flavours, but also a smart approach to add nutritional value to your treats. While desserts are often indulged as guilty pleasures, introducing fruits can transform these moments into healthier delights, enriching them with vitamins, minerals, and fibres. Whether you’re a home cook looking to improve your family’s diet or a culinary expert aiming to innovate your menu, adding fruits offers a myriad of benefits. These range from boosting the aesthetic appeal of your dishes with vibrant colours to enhancing the natural sweetness with a lower calorie count.

The tips provided here will help you seamlessly integrate more fruits into your dessert recipes, making them irresistibly wholesome and appealing to all ages. This approach not only caters to the health-conscious consumer but also opens up a palette of fresh, tantalizing flavours that can redefine what dessert means.

Explore Variety

Diversity is key in enriching desserts with fruits. Experiment with different textures and flavours, from berries to tropical fruits. This variety ensures each bite is unique and delightful. Try combining sour cherries with sweet mangoes, or add citrus segments to balance richer desserts. Even blending frozen bananas into a creamy texture can mimic ice cream. Consider adding a double fudge bar frozen dessert to your fruit platter for an indulgent twist.

Use Fresh and Seasonal Fruits

Seasonal fruits offer the best in flavour and nutrition. Incorporate fresh, local produce into your desserts to capture peak tastiness. Fresh strawberries or peaches can elevate simple dishes like ice cream or cakes. Local farmers’ markets are ideal for finding the freshest options. Remember, the closer the fruit is grown to its consumption point, the more nutrients it retains. This approach supports local agriculture as well.

Make Fruit the Star

Create desserts where fruits are the main attraction. Dishes like fruit tarts or berry-packed pavlovas highlight the natural sweetness of fruits, reducing the need for added sugars. Let fruits dictate the dessert’s flavour profile and design, focusing on the natural colours to attract the eye. This strategy can make even simple dishes feel luxurious and crafted with care. Plus, it often leads to lighter, less calorie-dense desserts.

Opt for Healthier Preparations

Instead of always baking or frying, try raw preparations or use healthier cooking methods like grilling or poaching. Grilled pineapple or poached pears offer a delightful texture and are easy to prepare. These methods preserve the integrity and nutritional value of the fruit better than baking or frying. Cooking fruit in this way can also unlock new flavours, enhancing your dessert experience. Try brushing fruit with a little honey or maple syrup before grilling for a caramelized finish.

Experiment with Spices

Spices can enhance the natural flavour of fruits. A dash of cinnamon, cardamom, or vanilla complements fruits like apples and pears beautifully, adding complexity to any dessert. Nutmeg and ginger are also excellent with juicy fruits like peaches and plums. Experimenting with spices can transform a simple fruit dish into an exotic and enticing dessert. Such additions are simple but effective ways to elevate the taste without added sugar.

Incorporate Dried Fruits

Dried fruits are concentrated in flavour and can be a great addition to desserts. Sprinkle raisins, dried cranberries, or chopped dates over oatmeal cookies or mix them into homemade granola bars for a chewy texture. Dried fruits work well in baked goods because they provide a burst of sweetness and texture. They are also perfect for decorating cakes and adding to snack mixes. Be mindful of the sugar content in store-bought dried fruits, opting for unsweetened varieties when available.

Create Colourful Fruit Layers

Layer fruits in parfaits, trifles, or cakes to create visually appealing and delicious desserts. Layers of colourful fruits not only look spectacular, but also offer varied flavours and textures. This layering technique can be applied in smoothie bowls and gelatin desserts for a stunning visual effect. Try to choose fruits that contrast in colour and texture for the most striking presentations. These desserts are particularly appealing to children and can make eating fruit more exciting for them.

Finish with A Healthy Twist

Top off your desserts with a nutritious twist, such as a dollop of Greek yogurt or a sprinkle of nuts and seeds for extra crunch and nutrients. These additions provide a contrast in textures and increase the health benefits of your dessert. Nuts add healthy fats and proteins, making the dessert more satisfying. Consider using a drizzle of natural sweeteners like honey or agave nectar to enhance flavour without resorting to refined sugars. Such finishes not only improve taste but also boost nutritional value, aligning with a healthier lifestyle.

Incorporating fruits into your desserts is an enjoyable way to make your sweet dishes healthier and more flavourful. By using fruits in various forms, from frozen to dried, and employing them in creative ways, such as natural sweeteners or vibrant toppings, you can transform any dessert into a delightful and nutritious treat. So next time you prepare a dessert, remember these tips and enjoy the added benefits of fruits in your culinary creations.

Everyone wants to make the most out of life. From personal life to establishing a successful career, enjoyment is all that people crave the most. But the key to happiness is having fun most of the time. It can be challenging to find time and moments of fun in the routine as life becomes boring and dull for many.

However, you can cultivate your mindset and embrace more pleasure and laughter in your everyday routine. To transform your boring and dull life into a fun-filled one, here are a few tips that you can consider in this blog.

Read on to explore!

 

1.    Start Enjoying Little Moments

The fun doesn’t need to come from an extensive and spectacular event happening around your life all the time. There are so many small moments in your life that can turn into more fun. All you have to do is embrace those little times in your life and be happy.

For example, you can give yourself a little break from a hectic day and enjoy some chocolate. Or you can make time to enjoy things that you like.

 

2.    Be Spontaneous In Life

Just like life becomes unexpected most of the time, you can be a little unpredictable with it as well. To bring fun to your life, you can work on being more open to new and unplanned experiences.

If you get an invitation for any activity, event, or sport, don’t say no to it. Getting to indulge in more social activities will help you create new memories and experience new thrills in life.

 

3.    Bring a Furry Friend in Life

A boring life can easily distance you from fun. To embrace joy in life, having a furry company can do wonders. You can cherish love and warmth and have little moments of joy with a furry one.

If you don’t have a furry companion, you’re majorly missing joy. It’s time for you to look for the best puppy-selling company, such as Fou Fou Puppie’s website, to bring a cute puppy into your life.

 

4.    Practice Mindfulness

Practicing mindfulness will help you to live the present to the fullest. As most people worry more about their future, it makes them overlook the current joys of life.

What you can consider best to bring fun to your life is practicing mindfulness for at least 2 minutes. Let go of all the thoughts that pop into your head and focus on the positive aspects of living.

 

5.    Participate More in Fun Activities

There should be no excuse for having fun in life as there are many low-cost fun activities for the community that you can explore to have fun. It can be simple, but it prevents you from living a boring and less-inspiring life.

For example, you can call your group of friends to have coffee together and share more laughter, or you can go to the movies to unwind yourself. These activities will not cost you a fortune and allow you to make the most out of your day, week, and month.
