What do we know about the different groups who are susceptible to the virus?
The ICNARC (Intensive Care National Audit & Research Centre) data certainly seems to show that BAME individuals have a predisposition for severe illness with Covid-19. For example, we know that over 90% of doctors who died of Covid-19 during the pandemic were from BAME backgrounds. An investigation has been conducted into the impact of Covid-19 on BAME communities, after it was discovered that people from black and Asian backgrounds had the highest death rates. People of Bangladeshi origin had twice the risk of dying compared with someone of white British ethnicity. Unfortunately, we know that healthcare inequalities do exist, even in this day and age. While this could be contributing there are also other factors like socio-economic inequalities, differing risks at work, and also the impact of other diseases such as diabetes, obesity, high blood pressure and asthma. We also know that vitamin D deficiency markedly increases your risk of developing severe Covid-19 symptoms. Vitamin D deficiency is more common in the BAME population, as their skin’s higher melanin content means they absorb less UV radiation and therefore produce less vitamin D.
Is there any reason to limit contact with children you don’t live with?
We know that children are at low risk of suffering badly with Covid-19, but what’s not yet clear is the impact of children on transmission. Schools and nurseries have implemented strict structures to minimise the risk of spread between children, and most have created bubbles within the school to help this happen. If you are vulnerable or elderly, then it is prudent to be careful. But we now have emerging studies which suggest that children are rarely the first person to bring the virus into a household. Take the opportunity to teach them good hand hygiene and spend time with them outdoors where possible. This pandemic has been particularly difficult for children – it’s important for them to return to education and to have social interaction again – we just need to be considered in how we do it.
How sensible is it to stay at a close family member’s house overnight?
It is now permitted for adults who live alone to form a social bubble with another household, and this can include staying overnight. It’s important to take sensible measures to decrease risk – consider bringing your own bed linen for example, and wash it afterwards. Continue to practice good hand hygiene. Make sure that before you meet up neither party is unwell in any way. The important thing to remember is that if one member of the bubble gets symptoms of Covid-19, then you will all need to self-isolate.
What are the medical risks when it comes to dating right now?
Dating is going to raise some interesting questions moving forwards. Rather than sitting next to each other on a couch in a bar, at what point will it become socially acceptable to enter each other’s personal space? There are the obvious risks of aerosol transmission as discussed above, but when we kiss or have sex we come into even more intimate contact. The chances of contracting the virus by kissing someone who is infected would be high. My advice would be to stick to dating one person at a time and don’t hop from partner to partner, as the risks of that behaviour could be high and you could be at the centre of your very own virus hotspot.
By resuming international travel are we risking a second wave?
Planes actually have better air quality than most offices. The air on a plane is completely changed every two minutes, which is reassuring. But what we do know is that when it comes to spreading other viruses (such as the common cold or flu), the passengers most at risk are those within two rows in front or behind an infected person, and in the row to the side. It is going to be impossible for airlines to block entire rows of seats, which is why wearing a mask while flying is so important. In an airport and on a plane there are also many surfaces which are touched by multiple people, so good hand hygiene is crucial. Also, be extremely careful when choosing where to fly to – monitor local infection rates and make a judgement call. The onus is on airlines and airports to effectively screen their travellers. Probably the biggest risk is that a second spike happens while you are on holiday, the country closes its airspace and you get stuck and/or have a lengthy quarantine – most of us cannot afford that much time out. There are also so many beautiful places to see in the UK, and taking staycations will help to boost the UK economy.
There are worrying reports about the US buying up medical supplies. Can you tell us more?
This is definitely concerning. The latest news is that the USA has bought almost the entire world supply of remdesivir, a drug which seems to reduce the duration of Covid-19 symptoms in clinical trials. The USA has a vast population and is, of course, one of the world’s wealthiest nations. By bulk buying they are depriving other countries of resources to protect and treat their population. That’s an issue even for wealthy but smaller countries like the UK who need lower volumes of stock, but it’s an even greater issue for less developed countries who will be unable to compete with the USA when buying PPE and medication.
What’s the latest update you can give us on a vaccine?
There are now over 200 vaccines in development around the world. A vaccine is extremely complex to develop, and the process usually takes several years. The scientists at Oxford University have been able to modify an existing vaccine, and they seem optimistic. One scientist has quoted an 80% chance of this being successful by September, and another scientist has quoted 50% – either way, those are positive numbers. The UK has already ordered 30m doses. If it’s successful, it will probably be given to vulnerable people first, and would not be given to anyone who has already had the virus due to the risk of immune reactions.
Is a vaccine the only way to eradicate Covid-19 for good?
The hope is that this would be enough to control the current outbreak, although complete eradication of Covid-19 is unrealistic at present. Although this may be possible in the long-term it would require vaccination programmes all over the world including in less developed countries without the resources to pay for expensive new vaccines. My verdict is that I’m hopeful, but there are no guarantees.
