How Have People Been ‘classifying’ Covid
You will have heard in public health announcements and in the media that some people have had mild COVID-19 infections, and others moderate, severe or critical.
Yet, when you look up the symptoms, you are told to expect a cough, a temperature and a loss of your sense of smell and/or taste. How bad a cough is a mild case? How much of a temperature is severe?
The terms generally used to classify the illness are:
These classifications are consistent with published descriptions so far. If formal, agreed guidance on what we call mild, moderate and severe cases is published, these may differ slightly. For now, this seems to fit the way the terms are being used.
Each of these ‘levels’ of illness is considerably less common than the previous one .
In this article we will look at asymptomatic and mild infections. In part two of the series we explain moderate, severe and critical COVID-19.
How Long Do You Test Positive After Having Had Covid
Because the PCR test is so sensitive, it can detect very small amounts of virus material. This means that the test can continue to detect fragments of SARS-CoV-2 virus even after youve recovered from COVID-19 and are no longer contagious. So you may continue to test positive if you’ve had COVID-19 in the distant past, even though you cant spread the SARS-CoV-2 virus to others.
Prolonged infection in immunocompromised individuals can occur where they shed infectious virus for months. Also, healthy people can become reinfected. If you test positive for SARS-CoV-2 but you think you might have already recovered from COVID-19, please discuss with a healthcare provider.
Healthy Diet And Lifestyle
The Harvard T.H. Chan School of Public Health recommends a healthy diet, being physically active, managing psychological stress, and getting enough sleep.
Consistently meeting scientific guidelines of 150+ minutes per week of exercise or similar physical activity was shown to be associated with a smaller risk of hospitalisation and death due to COVID-19, even when considering likely risk factors such as elevated BMI.
As of March 2021, there is no evidence that vitamin D status has any relationship with COVID-19 health outcomes. The largest clinical trial on the subject, with over 6 000 participants and a dosage regime near the RDI, is set to conclude in July 2021.

Coronavirus Disease : How Is It Transmitted
We know that the disease is caused by the SARS-CoV-2 virus, which spreads between people in several different ways.
The virus can spread from an infected persons mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe. These particles range from larger respiratory droplets to smaller aerosols.
- Current evidence suggests that the virus spreads mainly between people who are in close contact with each other, typically within 1 metre . A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth.
- The virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time. This is because aerosols remain suspended in the air or travel farther than 1 metre .
People may also become infected by touching surfaces that have been contaminated by the virus when touching their eyes, nose or mouth without cleaning their hands.
Further research is ongoing to better understand the spread of the virus and which settings are most risky and why. Research is also under way to study virus variants that are emerging and why some are more transmissible. For updated information on SARS-CoV-2 variants, please read the weekly epidemiologic updates.
Arriving From A Designated Country
If you arrive from a designatedcountry outside the EU or EEA, the rules will depend on if you have beenvaccinated or have recovered from COVID-19 in the past 180 days.
If you have proof of vaccination or recovery
You need to:
- Show a negative result from a RT- PCR test taken within 72 hours before your arrival
- Take a post-arrival test – this is provided through the HSE
If you do not have valid proof of vaccination orrecovery
You need to:
- Produce evidence of a negative result from a RT- PCR test taken within 72 hours before your arrival

What Other Proof Of Recovery Is Acceptable
If you do not have a DCC, your proof must be in written or electronic formatin English or Irish. If it is in a language other than English or Irish, itneeds to be accompanied by a certified translation.
Your proof of recovery must contain the following:
- Your full name and date of birth
- The date of your first relevant positive test result
- The disease or variant from which you have recovered

- Details of the body that issued the certificate
- Dates the certificate is valid from and expires
Effect On Other Diseases And The Pharmacy Trade
There was a report on 3 March 2021, that social distancing and common wearing of surgical masks and similar as a common precaution against COVID-19 caused such a drop in the spread rate of the common cold and flu that in Britain the sale of cough liquids and throat lozenges and from 30 November 2020 to 21 February 2021, was about a half of the sale a year earlier, and that Public Health England reported no cases of flu in the year 2021 to date, and that there was an 89% rise in sales of Vitamin D to try to boost immunity.

Causes Of The New Coronavirus
Researchers arenât sure what caused it and investigations as to its origin are ongoing. . Thereâs more than one type of coronavirus. Theyâre common in people and in animals including bats, camels, cats, and cattle. SARS-CoV-2, the virus that causes COVID-19, is similar to MERS and SARS. They all came from bats.
The Disease That Caused The Global Pandemic Will Likely Circulate For The Foreseeable Future Public
Many public-health experts anticipate that the world will be dealing with Covid-19 for the foreseeable future. That doesnt mean the pandemic wont end.
Instead, the disease will likely become endemic, meaning Covid-19 would continue to circulate among the population more predictably. The disease could eventually become more similar to routine illnesses like the flu or colds, common ailments that are less destructive and deadly than Covid-19 is now, virologists and epidemiologists say. The viruss long-term foothold in society depends on factors including vaccination coverage and how it continues to evolve.

How Safe Is Intimacy With A Partner During The Covid
If both of you are healthy and feeling well, are practicing social distancing and have had no known exposure to anyone with COVID-19, touching, hugging, kissing, and relationship are more likely to be safe. Similarly, sharing a bed with a partner who is healthy should not be an issue.
Be aware, though, that the CDC reports that some people may have the virus and not yet have symptoms during the early part of the incubation period . Additionally, some people never develop obvious symptoms of COVID-19 . In either case, its possible that the virus might spread through physical contact and intimacy.

Billion Children Out Of School
United Nations Secretary-General António Guterres has called the impact of COVID-19 on childrens education a generational catastrophe. At the initial peak of the pandemic in 2020, some 1.5 billion children were out of school due to school closures. The average child lost around half of their normal annual contact time with teachers. UNESCO estimates that the number of children not reaching an age-appropriate level of reading proficiency could rise by nearly 100 million to 581 million.
The impact of this learning loss will last decades. Not only might it take years for children to catch up with what they have lost, but lost learning may have long-term implications for earnings potential and economic development. Inequalities are likely to be exacerbated. One factor is that poorer children are less likely to have access to the internet and less likely to be able to benefit from online classes, if these are provided. Another is that the rise in poverty triggered by the pandemic is likely to cause more children of very low-income families to drop out of school. Girls are often more likely to be withdrawn from school, so the negative impact on the education of girls may be even greater than that for boys. An end to this disruption of education cannot come soon enough.
Are Digital Platforms Changing Expertise
Beyond the current public anger over the UKs handling of Covid-19, what does all this mean for the relationship between experts and society? The Channel 4 News interview was highly unusual normally, esteemed experts can keep themselves above the fray of the blogosphere and social media platforms. And when one reaches a certain level of fame, one can certainly understand the desire to mute their mentions. However, as Turner describes, the blogosphere does perform a vital task in qualifying the claims of accredited experts. Perhaps part of Pueyos success was the absence of detailed evidence or reasoning to support the claims of the UK government, and it is notable that Pueyo did not seek to criticise specific expert claims as is generally the case in the blogosphere. Rather, he made his own passionate and effective argument that observers could not help but notice stood in stark contrast with the stories from government experts.

What Does Fully Vaccinated Mean
You are fully vaccinated when you get a vaccine approved by theEuropean Medicines Agency and it is:
- 15 days after the second AstraZeneca dose or second Covishield dose
- 7 days after the second Pfizer-BioNtech dose
- 14 days after the second Moderna dose
- 14 days after the single dose
If you got a vaccine other than those listed above, you are notconsidered âfully vaccinatedâ.
You are also not fully vaccinated if the interval between your first andsecond doses is less than the required period .
Survivors Of Symptomatic Covid
Given the above data, it can be reasonably assumed that survivors of a severe COVID-19 infection would have similar outcomes to survivors of ARDS who did not have COVID-19. Having said this, it may well be that survivors of severe COVID-19 could suffer more chronic residual effects given the unique cardiac, cardiovascular, thromboembolic, and inflammatory complications of COVID-19.
Only a small percentage of patients with COVID-19 are ever admitted to the ICU, and data is starting to emerge about long-term sequalae occurring in COVID-19 survivors irrespective of pneumonia severity. One study of 143 COVID-19 survivors of mean age 56.5 years, only 13% of whom had been admitted to an ICU, found that nearly 90% of the study group were experiencing persistent symptoms two months after the onset of their illness. At a mean of 60.3 days after onset of first COVID-19 symptoms, 12.6% were completely free of any COVID-19-related symptoms, 32% had one or two symptoms, and 55% had three or more. In addition, 44.1% reported a worsened quality of life post-COVID-19 onset.28

Financial Flows At Risk
Businesses in financial trouble could spell bad news for banks. Although they have so far proved resilient, banks often suffer in the aftermath of economic crises, as bad debts build up on their books, even as the rest of the economy starts to pick up. There is a strong risk that rising numbers of non-performing loans could increasingly constrain the ability of banks to lend to healthy businesses. Preliminary results from a survey of banks in Africa, carried out by the EIB Economics Department in early 2021, reveal what these banks see as the main ways the pandemic is affecting them so far. Those effects are declining asset quality as well as reduced demand for loans, mirroring what we see from surveying businesses.
In the end, the severity of the economic impact of the pandemic will depend a lot on whether governments are able to implement policy support that cushions the shock and supports recovery, keeping businesses afloat and people in employment. As well as aid to businesses, continued spending on public services, welfare systems and infrastructure is vital to support the recovery and prevent the negative consequences of the pandemic multiplying even further. This requires finance. On top of an annual $2.5 trillion gap to achieve the Sustainable Development Goals, the OECD estimates the gap in COVID-19 recovery spending for developing countries to be in the order of $1 trillion per year.
How Long Should Quarantine Or Isolation Last
Recommendations for how long people should quarantine or isolate change often and can vary depending on:
- where they live
For the latest updates, visit your local health department’s website or the Centers for Disease Control and Prevention website.
In general, the CDC recommends that unvaccinated people:
- Quarantine for 14 days after contact with an infected person. Newer guidelines recognize how hard it can be for someone to be out of work or school for that long. So, some local public health authorities allow for:
- a 10-day quarantine plus 4 more days of watching closely for symptoms
- a 7-day quarantine if a COVID-19 test result is negative after the 5th day
The CDC says that people who develop COVID-19 symptoms or get infected with coronavirus should:
- Isolate for 10 days from the time their COVID-19 symptoms started, or from the date they tested positive, as long as that includes 1 full day without a fever and other symptoms get better. Testing usually isn’t needed to decide when to stop isolation.
Someone who starts to feel sick during quarantine should switch to isolation and add 10 more days. If they start to feel sick near the end of their quarantine period, it could mean staying at home for as long as 24 days. This can be very hard, but it is important to do so to prevent spreading the virus to others.

Mitigation Strategies For Annual Programmes
Temporal microfilarial prevalence trends
Both models suggest that for a programme with a short treatment history, increasing treatment frequency, i.e. implementing remedial biannual MDA at 65% coverage upon resumption of MDA, will be more effective at reducing the impact of treatment disruptions than increasing treatment coverage . We illustrate these results after a 2-y interruption when MDA initially resumes at low annual coverage , returns to annual 65% coverage and then either increases to a 6-month frequency for 2 consecutive years at 65% coverage or increases to 75% annual MDA coverage also for 2 consecutive years . Remedial biannual treatment results in lower microfilarial prevalence leading up to 2030 than remedial increased coverage . The temporal microfilarial prevalence dynamics for a 1-y interruption with either remedial increased treatment frequency or coverage are shown in Supplementary Figures S7 and S8.
Elimination probabilities with remedial strategies
For a 2-y interruption, although neither remedial strategy is sufficient to achieve the same elimination probabilities found in the absence of an interruption, 2 y of remedial biannual MDA results in higher elimination probabilities than a remedial increase in coverage . For some treatment histories and pre-intervention endemicities , 1 y of missed MDA followed by 1 y of remedial biannual MDA gives similar elimination probabilities as those in the absence of MDA disruptions .
How To Get Tested For Current Covid
- Contact your healthcare provider or visit your state, tribal, localexternal icon, and territorial health departments website to find the latest local information on testing. The type of viral COVID-19 tests offered may differ by location.
You and your healthcare provider might also consider either an at-home collection kit or an at-home test if you have signs and symptoms of COVID-19 and if you cant get tested by a healthcare provider or public health official.

How To Use Results Of Viral Tests
- If you test positive, know what protective steps to take to prevent others from getting sick.
- If you test negative, you probably were not infected at the time your sample was collected. The test result only means that you did not have COVID-19 at the time of testing. Continue to take steps to protect yourself.
Does Coronavirus Spread Outside
Yes, but only slightly. When youre outdoors, youre not in a confined area with poor air circulation. Its important to wear a mask both inside and outside if you cannot guarantee proper social distancing, which is at least six feet of distance from other people.
