Scientists from the Zoe Covid Study in the UK claim that the symptoms of the Omicron variant of COVID-19 are similar to those of the common cold. There are five common symptoms reported by Omicron positive patients. Common Omicron symptoms include headaches, fatigue, sore throat, runny nose, and sneezing. The symptom data was obtained from 171 users of the Zoe Covid application as of Friday, December 24, 2021. Tim Spector, Professor of Genetic Epidemiology at King's College London and co-founder of Zoe, said: "For some people who test positive for the Omicron flu-like symptoms, ranging from sore throat, runny nose and headache. Spector said, some patients also reported general symptoms similar to COVID-19, such as fever, cough, or loss of sense of smell and taste. Researchers in Norway recently reported finding similar Omicron variants among fully vaccinated Christmas party guests. In the 87 confirmed or probable cases, the most common symptoms were cough, runny nose, stuffy nose, fatigue, sore throat and headache. More than half reported a fever, while 23 percent experienced a loss of taste, and 12 percent experienced a decrease in smell. This case is proof that the Omicron variant is the most infectious variant and can penetrate the immune system of the complete vaccine recipient. However, the sufferer did not experience severe illness, especially for the booster vaccine recipients. "We will continue to hear about more infected people being vaccinated. These people may get a mild or asymptomatic infection, and may unknowingly spread the infection to others," said Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky. In South Africa, widespread vaccination of people who have had COVID-19 could explain Omicron's symptoms tend to be milder. Vaccines are believed to be effective in preventing the severity of disease caused by Omicron. "We believe not only is omicron less virulent, but we believe this vaccination coverage, in addition to the natural immunity of people who have been in contact with the virus, also adds protection," South African Health Minister Joe Phaahla said recently. Even so, some people with Omicron can get very sick starting with a number of symptoms. According to the CDC, symptoms of COVID-19 due to infection with the omicron variant require medical treatment. Moreover, some symptoms need emergency treatment. The following symptoms can cause infection with the Omicron variant: 1. Sudden confusion 2. Easy to fall asleep 3. Pain 4. Hypertension 5. difficulty breathing 6. Lips, nail beds, and skin turn blue, pale, or gray. Symptoms of the Omicron Variant Are Different from the Common Flu Symptoms of the Omicron variant are more or less similar to those of the common cold. So that the two are quite difficult to distinguish because they both affect the respiratory system. However, there is a slight difference in the symptoms of the Omicron variant and the common cold. Experts warn that the Omicron variant has two different symptoms from the common cold. Initial studies conducted to understand the symptoms of the Omicron variant show that the Covid-19 corona virus does not have the same symptoms as other variants. According to experts, each variant of the corona virus is indeed have different symptoms. The same thing happened to the Omicron variant. Although the Omicron variant looks similar to the symptoms of the common cold, there are two symptoms of this corona virus variant that are slightly different from a cold, namely headaches and fatigue. According to the World Health Organization (WHO), the new variant can infect more people because it is three times more contagious than the previous variant. In some cases, this Omicron variant is also able to penetrate antibodies induced by the Covid-19 vaccine as well as natural infections in the past. , the symptoms of the Omicron variant may not be as severe as the Delta variant which caused a second wave and claimed millions of lives worldwide in early 2021. More research on the Omicron variant is still needed, some common symptoms include: Mild fever Fatigue Itchy throat body ache Unlike previous cases of Covid-19 coronavirus infection, the Omicron variant may not cause the loss of sense of smell and taste that is a sign of coronavirus infection. Experts have not been able to distinguish the symptoms of the Omicron and Delta variants. Data collected so far reveals that only 50 percent of people experience common symptoms of the coronavirus, namely high fever, persistent cough and anosmia.
