Does sleep apnea make Covid worse?
Rachel Ellis
Published Jan 17, 2026
In conclusion, patients with OSA have the same risk of contracting COVID-19 than non-OSA individuals. Meanwhile, in this study, patients with OSA had 2.93 times higher risk to be hospitalised when affected by COVID-19 than non-OSA individuals.
Who are at higher risk of developing serious illness from COVID-19?
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
Can you get COVID-19 more than once?
Yes, it is possible to get Covid-19 two, three or even more times. As new variants have emerged, and immunity from previous infection and immunisation has reduced over time, reinfection with Covid-19 has become increasingly common.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19
How do I know if Im clinically vulnerable for COVID-19?
You may previously have received a letter or email identifying you as someone who is clinically extremely vulnerable ( CEV ), and you may have been advised to shield during earlier stages of the pandemic.
How long after having COVID-19 can I get the spring booster vaccine?
If you are unwell, wait until you have recovered to have your vaccine. If you have had confirmed COVID-19 you should ideally wait 4 weeks before having your spring booster.
Does obesity put me at high risk for COVID-19?
Living with excess weight puts people at greater risk of serious illness or death from COVID-19, with risk growing substantially as body mass index (BMI) increases. Nearly 8% of critically ill patients with COVID-19 in intensive care units have been morbidly obese, compared with 2.9% of the general population.
What are the complications of COVID-19?
Complications may include pneumonia, acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and death.
In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
What should I do if I have COVID-19 vaccine side effects?
Most side effects are mild or moderate and go away within a few days of appearing. If side effects such as pain and/or fever are troublesome, they can be treated by medicines for pain and fever such as paracetamol.
Can you still catch COVID-19 after having the booster vaccine?
Can you still catch COVID-19 after having the vaccine? The COVID-19 vaccination will reduce the chance of you suffering from COVID-19. It may take a few days for your body to build up some protection from the booster.
Can you still get Covid after vaccine?
Like all medicines, no vaccine is completely effective, so you should continue to take recommended precautions to avoid infection. Some people may still get COVID-19 despite having a vaccination, but this should be less severe.
Can I become infected with COVID-19?
COVID-19, along with many other respiratory infections such as influenza (flu), can spread easily and cause serious illness in some people. You may be infected with a respiratory virus such as COVID-19 and not have any symptoms but still pass infection onto others.
Are the elderly more vulnerable to the coronavirus disease?
The COVID-19 pandemic is impacting the global population in drastic ways. In many countries, older people are facing the most threats and challenges at this time.
Although all age groups are at risk of contracting COVID-19, older people face significant risk of developing severe illness if they contract the disease due to physiological changes that come with ageing and potential underlying health conditions.
Are smokers at higher risk of developing severe respiratory disease from COVID-19?
The evidence clearly shows COVID-19 virus attacks the respiratory system, which explains why smokers are at greater risk. A small but highly impactful survey from China finds that smokers with COVID-19 are 14 times more likely to develop severe disease.
Who can get a spring booster for the coronavirus disease?
People aged 75 years and older, residents in care homes for older people, and those with weakened immune systems will be offered a spring booster of coronavirus (COVID-19) vaccine. Appointments will be available from the National Booking Service shortly.
Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).
The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
How long have coronaviruses existed?
The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.
Can COVID-19 spread through water while swimming?
Fact: Water or swimming does not transmit the COVID-19 virus
The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person.
WHAT YOU CAN DO:
Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.
What are the common side effects of the COVID-19 vaccine?
Common side effects
- having a painful, heavy feeling and tenderness in the arm where you had your injection. This tends to be worst around 1 to 2 days after the vaccination
- feeling tired
- headache
- general aches, or mild flu like symptoms
Can COVID-19 lead to mental and neurological complications?
Meanwhile, COVID-19 itself can lead to neurological and mental complications, such as delirium, agitation, and stroke. People with pre-existing mental, neurological or substance use disorders are also more vulnerable to SARS-CoV-2 infection ̶ they may stand a higher risk of severe outcomes and even death.
Can people with mild COVID-19 symptoms recover at home?
People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
What is a healthy diet during the COVID-19 pandemic?
• Every day, eat a mix of wholegrains like wheat, maize and rice, legumes like lentils and beans, plenty of fresh fruit and vegetables , with some foods from animal sources (e.g. meat, fish, eggs and milk).
• Choose wholegrain foods like unprocessed maize, millet, oats, wheat and brown rice when you can; they are rich in valuable fibre and can help you feel full for longer.
• For snacks, choose raw vegetables, fresh fruit, and unsalted nuts.
Who is eligible for the domestic NHS COVID-19 pass?
The domestic NHS COVID Pass is available to those aged 18 and above.
Can I develop immunity to COVID-19 after testing positive for PCR?
If you have previously tested positive for COVID-19, you will probably have developed some immunity to the disease. However, it cannot be guaranteed that everyone will develop immunity, or how long it will last. It is possible for PCR tests to remain positive for some time after COVID-19 infection.
