Know The Basic Difference Between Omicron, Flu and Common Cold in 2022

Know The Difference Between Omicron, Flu and Common Cold

There has been a major upheaval caused by the COVID-19 pandemic that has affected the whole world. It only seems to get worse as the situation gets worse with the new variant, Omicron, and the daily increase in Covid-19 cases.The World Health Organization (WHO) denied that the new strain is mild, although it appears to be milder than Delta, especially among those who are vaccinated. On January 6, experts speculated that the new strain was milder than Delta.

The Omicron mutation is a highly mutated variant with a rather unusual combination of genetic mutations that is unlike those seen in other variants over the past two years. In fact, the Centre for Epidemic Response and Innovation in South Africa found Omicron to have more than 30 mutations on the spike protein and over 50 mutations overall.


 The symptoms of Omicron are similar to the symptoms of the common cold and influenza. This disease has several symptoms, including a sore throat, runny nose, body pain, and fever. When influenza strikes, people usually experience similar symptoms. The flu usually peaks in the middle of winter, between early October and mid-February. As the symptoms of respiratory infections are mild and similar, it is difficult to distinguish between them.

Several reasons have been attributed to its widespread spread, including the outbreak of Omicron – a new variant of SARS-CoV-2 coronavirus – which has resulted in incredible increases in daily Covid-19 numbers. Despite a debate currently raging among public health professionals and infectious diseases experts regarding Omicron’s lethality, a number of studies indicate that its feeble attack on the lungs could make it less dangerous than predecessors like Delta, which were much more lethal.

Despite this, almost all scientists and medical professionals warn of caution, given the highly mutated state of the virus and the enormous amount of evolutions this variant has been capable of. As a result of such a scenario, it is sometimes difficult to make a precise diagnosis of whether someone has Omicron when experiencing symptoms that also resemble those of a common cold or influenza.

All three types of colds, influenza, or Coronavirus (Covid-19), which are caused by Omicron, result in symptoms such as runny nose, sore throat, fever, and body ache. The common cold is almost always the prime suspect in most of these cases. During the winter, the influenza virus peaks from early October to mid-February, so it might also be tempting to consider this option.


As a result, given that Omicron cases have risen dramatically over the past few days, the possibility also exists that the person may have contracted the variant spreading rapidly.

Despite this, experts believe that there is no quick and sure-fire test to determine whether someone has Omicron. There are a few workarounds to guide an educated guess, however the importance of testing here is highlighted more than ever since it is very difficult to tell Omicron from the common cold, especially, based simply on symptoms.

The media publication quoted Professor Eskild Petersen from the Aarhus University Hospital in Denmark as saying,  ” I consider it impossible to differentiate a common cold from Omicron. “

Coronavirus-19, influenza, and the common cold manifest themselves as the following symptoms, in order of frequency:

  • Dry cough: Covid-19 (frequently), flu (frequently), cold (occasionally)
  • A fever is usually caused by Coronavirus-19 (very common), influenza (regular), or a cold (rare)
  • Stuffy nose: covid-19 (rarely), flu (sometimes), cold (frequently)
  • A sore throat can be caused in Covid-19 (sometimes), flu (sometimes), or cold (often).
  • Breathing problems: COVID-19 (from time to time), flu (not observed), cold (not observed)
  • Headache: Covid-19 (rarely), flu (often), cold (not seen)
  • Aches in the body: Covid-19 (sometimes), flu (frequently), cold (frequently)
  • Frequently sneezing: Covid-19 (not observed), flu (not observed), cold (frequent)
  • Exhaustion: Covid-19 (occasionally), influenza (frequently), cold (occasionally)
  • Diarrhea: Covid-19 (rarely), flu (occasionally), cold (rarely)

A professional will usually recommend getting tested and undergoing self-isolation at home if you are experiencing symptoms. Nonetheless, the best course of action is simply to get tested. The sensitivity of rapid tests in detecting Omicron might be a little lower, but RT-PCR (reverse transcription-polymerase chain reaction) tests are frequently seen as being the most accurate and reliable way to determine whether an individual has Covid-19. Should the patient’s sample be detected to be Covid-19, the sample will be sent to a specialized laboratory to determine which variant of the infection is present.

As Dr. Jill Weatherhead of Baylor College of Medicine in Houston tells the magazine,  ”  the most important thing to do is to assess our risk tolerance, and to make sure we are making the right decisions, especially during this highly contagious period. ” 


It has been reported that mild infections caused by the Omicron variant cause a number of symptoms similar to those associated with the common cold. In addition to headaches, a sore throat, a runny nose, fatigue and frequent sneezing, there are frequently associated symptoms that seem like a typical cold or flu.

Even though reports claim Omicron is similar to a common cold, the World Health Organization (WHO) did not believe it was the flu and warned that it should not be dismissed.

A UK research group recently added nausea and loss of appetite to the list of symptoms listed by its app.

According to sources, there have been several studies from South Africa, the United States, and the United Kingdom showing that infections caused by the highly transmissible variant are in general mild, requiring less hospital care.

According to WHO epidemiologist Dr Maria Van Kerkhove’s tweet about the micron, it is not the common cold.

The health hazards associated with Omicron (and Delta) continue to kill too many people, she said.  In comparison to Delta, Omicron (and Delta) seem to cause fewer hospitalizations, but there are still far too many people who are infected, hospitalized, and die from exposure to these chemicals. 


It has been reported that fourteen deaths have occurred in the UK due to the Omicron variant, but only one in the U.S. and one in South Korea. Unvaccinated individuals are nearly exclusively responsible for the deaths.

Soumya Swaminathan, WHO’s chief scientist, reiterated his tweet from earlier this week:  ” Omicon is not a common cold! Health systems can get overwhelmed. ” .

 ” It’s very important to have systems in place that are capable of testing, advising, and monitoring a large number of patients, since large backlogs of patients can occur suddenly and with little warning, ”  she said.

In his remarks, Kerkhove stated that ensuring vaccine equity will allow us to  ” prevent infections and save lives today. ” .

During Tuesday’s press conference, the WHO confirmed that newly emerging evidence indicates the Omicron has affected the upper respiratory tract, causing milder symptoms than previous variants.

According to the growing body of research showing that Omicron causes serious pneumonia, it has primarily affected the upper part of the body, not the lower, said WHO Incident Manager Abdi Mahamud to Geneva-based journalists.

Media reports also mentioned that the global health body was warning that a spike in Omicron infections may lead to the development of new variants of the disease. A variant that spreads more rapidly is more likely to be able to replicate and create a new variant with more lethal characteristics.

French researchers have discovered a new variant, dubbed IHU. Scientists have documented 12 cases of infections with this new variant, which has 46 mutations, both for vaccinated and unvaccinated people. Omicron, which is touted to be highly transmissible, mildly infectious, and less lethal than Delta, could pose a greater threat to the world, but  ” it is far too early to draw any conclusions about its virological, epidemiological, or clinical characteristics given that so few cases have been reported. “
