Study of twins reveals genetic effect on Covid-19 symptoms

Symptoms of Covid-19 appear to be partly down to genetic makeup, researchers at King’s College London have discovered. The finding is based on data collected through the Covid-19 Symptom Tracker app, launched by the team last month. The team then focused on data from just over 2,600 twins to try to establish whether the symptoms experienced by those predicted to have Covid-19 is related to genetic makeup. More specifically, the team found a substantial genetic influence for the symptoms of fever, diarrhoea, delirium, and losses of taste and smell. FAQs: Facts about COVID-19 as per World Health Organization (Microsoft) (Pictured) The Public Service Hall is disinfected to prevent the spread of COVID-19, in Tbilisi, Georgia, on March 3.  Coronaviruses are a large family of viruses which may cause illness in animals or humans. (Pictured) Commuters wear protective masks at Hankou railway station in Wuhan on Jan. 22. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. Older people, and those with underlying medicalproblems likehigh blood pressure, heart problems or diabetes, are more likely to develop serious illness. (Pictured) A health personnel monitors body temperature of passengers who arrived in a flight from Milan, Italy, in Balice, Poland, on Feb. 26. Studies to date suggest that the virus that causes COVID-19 is mainly transmitted through contact with respiratory droplets rather than through the air.  (Pictured) A pedestrian wears a face mask in Toronto, Canada, on Jan. 29.  The main way the disease spreads is through respiratory droplets expelled by someone who is coughing. While initial investigations suggest the virus may be present in feces in some cases, spread through this route is not a main feature of the outbreak. (Pictured) Bruce Aylward, team leader of the joint mission between WHO and China on COVID-19, speaks at a press conference in Geneva, Switzerland, on Feb. 25.  (Pictured) A sign reminding people to wash their hands is seen outside a dormitory at the Washington State Patrol Fire Training Academy in North Bend, U.S., on Feb. 6.  The risk depends on where you live or where you have traveled recently. For people in most other parts of the world, your risk of getting COVID-19 is currently low,however, it’s important to be aware of the situation and preparedness efforts in your area. (Pictured) A crew member sprays disinfectants on the seats of a Thai Airways plane on Jan. 28. Your healthcare provider, your national public health authority and your employer are all potential sources ofaccurateinformation on COVID-19 and whether it is in your area. (Pictured) Indians who were air-lifted from Wuhan following the outbreak wait to collect release certificates at a quarantine facility in New Delhi on Feb. 17. (Pictured) A customer checks face masks at a pharmacy in Buenos Aires, Argentina, on March 3.  Not yet. (Pictured) A researcher works in a laboratory to develop a vaccine at Philipps-University Marburg in Germany on Jan. 31.  People with no respiratory symptoms, such as cough, do not need to wear a medical mask. (Pictured) Workers pack protective face masks in Ahmedabad, India, on Feb. 3.  The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. (Pictured) Workers set up beds at an exhibition center that was converted into a hospital in Wuhan on Feb. 4.  Coronaviruses are a large family of viruses that are common in animals. There is no evidence that companion animals or pets such as cats and dogs have been infected or could spread the virus that causes COVID-19. (Pictured) Dogs wearing masks are seen in a stroller in Shanghai, China, on Feb. 19.  It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity ofthe environment). (Pictured) A professional in protective gear sprays antiseptic solution in Seoul, South Korea, on Feb. 26. (Pictured) Employees sort parcels at a Russian Post logistical center in Moscow on Feb. 5.  The following measures ARE NOT effective against COVID-2019 and can be harmful: In any case, if you have fever, cough and difficulty breathing seek medical care early to reduce the risk of developing a more severe infection and be sure to share your recent travel history with your health care provider. “I think you can say that your likelihood of getting it at all, or getting it severely, is under some genetic control.” The team hopes the findings will help scientists ascertain the mechanisms by which Covid-19 acts on the body, as well as offering a possible way to predict those most at risk from the disease. “Understanding how symptoms of [the disease] Covid-19 pass through the population may indicate the pathogenic mechanisms of [the virus] Sars-CoV-2 infection, as well as offering utility in the allocation of scarce healthcare resources, particularly intensive care beds,” the team writes. They say the results could also help researchers around the world identify genetic variants that play a role in explaining why some individuals show no, or only mild, symptoms of Covid-19, which could in turn aid the development of drugs for the disease. But there were other possible targets, Spector said, noting that genetics were closely linked to the immune system and microbes found in the gut.
