- 新冠肺炎, the flu, a cold, and allergies have different symptoms.
- The main symptoms of COVID-19 are fever, tiredness, cough, and shortness of breath.
- 过敏具有更长期的症状，包括打喷嚏，喘息和咳嗽。
- COVID-19流感症状相似,如fever and body aches, but it doesn’t usually cause shortness of breath.
如果你有流鼻涕或痒的眼睛，它并不一定意味着你有Covid-19。
But if you have a cough, fatigue, a fever, shortness of breath, or loss of taste or smell, there’s a much greater chance you have COVID-19.
Then again, it could also be the seasonal flu.
That’s why a good rule of thumb is, when in doubt, you may want to consider getting tested for COVID-19.
“Not all symptoms are created equally. While it might seem like you have coronavirus, you may simply be experiencing seasonal allergies or influenza,”Lindsey Elmore，专门，董事会认证的药物疗法专家和主持人“Lindsey Elmore展”，讲作健康线。雷竞技app官网
It’s worth noting, however, that the 2020-21 flu season was unusually mild, according to the
“There are many symptoms of cold, flu, and COVID-19 that are similar, and it may be difficult to distinguish,” saidRamzi Yacoub, PharmD, chief pharmacy officer of the prescription savings service SingleCare. “They’re all caused by viruses, but different viruses cause each of these infections.”
“However, one key difference between the three is a symptom of [COVID-19] is shortness of breath,” Yacoub told Healthline. “Shortness of breath is a common symptom of COVID-19, which occurs prior to the development of pneumonia.”
“一般来说，流感或寒冷不会造成呼吸急促，除非它已经进入肺炎，在这种情况下，您也希望联系您的医疗保健专业人士，”Yacoub说。
Dr. Subinoy DasTivic Health的首席医务人员表示，普通感冒很少引起发烧后发烧后的呼吸急促。
“Influenza does mimic COVID-19 very closely, but the shortness of breath is not usually as severe as it is with COVID-19,” Das told Healthline.
DAS说，随着Covid-19，呼吸急促经常发生在发烧的第一个迹象后5至10天。
卫生官员正在表达担忧
TheOmicron variant，首次报道11月下旬提出了担忧，但到目前为止似乎似乎相对温和。
The Delta variant still accounts for more than 90 percent of new infections.
TheDelta variantwas first detected in the United States in March 2021. Delta — like the others — appears to be more infectious. It causes particularly severe symptoms, although vaccinated people are still highly protected against it.
Delta变体导致更多年轻人开发Covid-19感染的青少年比以前的变种，也可能导致稍微不同的症状而不是其他变体。
“If you talk with pediatricians in the field, they tell you that kids are presenting with symptoms associated with the common cold and other upper respiratory infections, such as headache, runny nose, sinus congestion, and sore throat,”Dr. Inci Yildirim是康涅狄格州耶鲁医学的儿科传染病专家和患有疫苗学家，告诉健康线。雷竞技app官网
这些症状更常见与普通感冒相关，并且通常与Covid-19的早期呈现不相关。
However, Yildirim cautioned that these reports don’t necessarily mean that the Delta variant causes different symptoms, but rather may reflect COVID-19’s differing impact on younger people.
Vaccinated individuals also can get COVID-19, although their risk of infection is far lower than for unvaccinated individuals. Unvaccinated people are
When vaccinated people do get COVID-19, they typically exhibit symptoms that are less severe than those experienced by unvaccinated people who have the infection. Research from theZoe COVID Study, which tracks symptoms of the disease among people in the United Kingdom, found that the top symptoms for vaccinated people who get COVID are headache, runny nose, sneezing, sore throat, and persistent cough.
Vaccinated people were less likely to experience some other “traditional” symptoms of COVID-19 infection, such as shortness of breath, fever, and loss of sense of smell.
“Generally, we saw similar symptoms of COVID-19 being reported overall … by people who had and hadn’t been vaccinated,” according to a report from the Zoe COVID Study. “However, fewer symptoms were reported over a shorter period of time by people who had already had a vaccine, suggesting that they were feeling less seriously ill and getting better more quickly.”
Here’s a look at common symptoms of COVID-19, the flu, a cold, and allergies.
A runny nose, facial pain, postnasal drip, and itchy eyes are common symptoms of allergies or the common cold.
But itchy eyes and facial pain are not typical symptoms of COVID-19.
“The most common symptoms of COVID-19 are fever, tiredness, and dry cough,” according to the
“In a report from China of more than 1,000 patients, nasal congestion was seen in only 1 out of every 20 patients,”Kristine S. Arthur博士, an internist at MemorialCare Medical Group in Laguna Woods, California, told Healthline.
然而，一些研究表明Covid-19症状随着疾病突变而改变并且影响了不同的群体。
例如，打喷嚏曾经被认为是Covid-19感染的令人罕见的症状。现在，它是最常见的症状。
新冠肺炎symptomsusually appear 2 to 14 days after exposure — a window that can be wider than is typical for the flu, which usually presents symptoms within 1 to 4 days of transmission.
The

- cough
- 呼吸急促或呼吸困难
- 疲劳
- muscle or body aches

- new loss of taste or smell
- 咽喉痛
- congestion or runny nose
- 恶心或呕吐
- diarrhea
So far, thesymptoms of the Omnicron variantappear to closely resemble those of the Delta variant.
Many of the initial people to contract this variant report muscle aches as well as fever, coughing, and shortness of breath.
然而，其中一些人表示他们没有经历味道或嗅觉的损失。
Some people who develop a COVID-19 infection don’t have any symptoms or feel unwell. Nevertheless, these people can still transmit the coronavirus to people around them.
新冠肺炎, like the flu or common cold, is an acute illness, meaning people feel fine until symptoms start showing up.
Allergies, on the other hand, “are usually chronic, presenting with symptoms off and on for weeks, months, or even years,”Dr. David M. Cutler, family medicine physician at Providence Saint John’s Health Center in Santa Monica, California, told Healthline.
“过敏不应该引起发烧或身体疼痛，”亚瑟说。“一般来说，除非你有很多鼻引流，否则没有咳嗽。”
Conversely, itchy eyes and facial pain are more typical of allergies than a COVID-19 infection.
过敏也可能导致喘息,她说,易翔ially in people with asthma.
“Allergy symptoms tend to vary with the environment: worsening with exposure to dust, pollen, or animal dander, whereas cold symptoms tend to persist regardless of time of day, weather, locality, or other environmental factors,” Cutler said.
Also, as with COVID-19, “colds are more likely to have generalized symptoms like fever, headache, and body aches, whereas allergies usually affect only the respiratory tract,” Cutler said.
“Allergy symptoms tend to improve with antihistamine and other allergy-specific medication,” he said. “Colds are more likely to respond to decongestants, acetaminophen, fluids, and rest.”
The
原子能机构表示，诸如呼吸急促，咳嗽，疲劳，头痛和喉咙痛等事物可以是Covid-19或过敏的症状。
但发热，肌肉酸痛，味道或气味，恶心和腹泻与Covid-19无过敏。
新冠肺炎is not the flu.
As one of a class of pathogens known as coronaviruses, COVID-19 is actually more closely related to the common cold than the seasonal flu.
However, despite some overlap, the typical symptoms of COVID-19 are more similar to the flu (fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, fatigue) than the common cold (runny or stuffy nose, sore throat, cough, congestion, slight body aches, mild headache, sneezing, low-grade fever, malaise).
The Delta variant, however, may have more cold-like symptoms.
“In terms of differentiating between flu and COVID-19, it can be almost impossible to distinguish,”Dr. Jake Deutsch，纽约治愈紧急护理及专业输注的联合创始人和临床主任。“这就是为什么人们建议有流感疫苗接种，所以它至少可以消除鉴于其他一切的流感风险。”
“Fevers, body aches, coughing, sneezing could all be equally attributed to them both, so it really means that if there’s a concern for flu, there’s a concern for COVID-19,” Deutsch said.
Yildirim说，当你生病的时间和地点可能是您感冒，流感或Covid-19的最佳预测因子。
生活在疫苗接种率低的社区的人和Covid-19“的高率更有可能有Covid-19，”她说，特别是在寒冷和流感季节之外。
然而，她说，当所有三种疾病可能都是普遍的时，冬季变化变化变得更加困难。
如果皮带器说，如果您有轻度COVID-19，流感或寒冷，患有症状的治疗措施。
“Generally, acetaminophen is recommended for fevers,” he said. “Cough drops and cough syrups can also help keep mucous secretions thinner. If there is associated nasal congestion, antihistamines may be useful.”
Another good reason to get a flu shot is that it may help protect against severe COVID-19 symptoms like sepsis, stroke, and deep vein thrombosis, according to research from the Netherlands published in the journal PLoS One.
Also, someinfectious disease experts worrythat because so few people got flu infections during the 2020-21 flu season, weak natural immunity rates could cause a surge in flu infections during the 2021-22 flu season.
卡特勒认为，Covid-19的轻度案例是持续约2周。
“Fortunately, the vast majority of cases are mild,” he said.
如果您完全接种疫苗，这尤其如此。
几乎没有人死于感冒。和最seasonal allergies are more annoying than dangerous.
Influenza, however, causes between
新冠肺炎can cause more serious illness, especially among unvaccinated people, although treatments have improved in the past year. An estimated97 percent与Covid-19疾病住院的人都没有被解雇，而是来自英国的一项研究发现就是0.5％of COVID-19 deaths were among vaccinated individuals.
Severe symptoms of COVID-19 that require immediate medical attention include:
- difficulty breathing
- persistent pain or pressure in the chest
- confusion or inability to arouse
- bluish lips or face
蓝色嘴唇或面部表明血液中的氧气短缺。

“People ages 60 years and over, and people with underlying medical problems like high blood pressure, heart and lung problems, diabetes, obesity or cancer, are at higher risk of developing serious illness,” the WHO said.
