Are smokers more likely to develop severe disease with COVID-19?
Around the world, more than 8 million people lose their lives each year due to tobacco use. More over seven million of these fatalities are directly attributable to the use of tobacco, and approximately one and a half million are attributable to the exposure of non-smokers to second-hand smoke.
The use of tobacco products is a well-known risk factor for a wide variety of respiratory illnesses and can make respiratory ailments more severe. When compared with non-smokers, smokers have a much higher risk of developing severe COVID-19-related illness, according to the findings of a review of research carried out by experts in the field of public health and carried out by WHO on April 29, 2020.
The lungs are the primary organ targeted by the infectious illness known as COVID-19. The function of the lungs is negatively affected by smoking, which makes it more difficult for the body to fight against infections such as coronaviruses. Tobacco use is one of the most significant contributors to the development of noncommunicable diseases such as cardiovascular disease, cancer, respiratory disease, and diabetes.
People who already have one of these conditions have a greater likelihood of developing a severe illness if they are exposed to COVID-19. According to the study that has been done so far, those who smoke have a significantly increased chance of acquiring serious diseases and passing away.
The World Health Organization (WHO) continually assesses newly published research, including research that investigates the connection between tobacco use, nicotine usage, and COVID-19. The World Health Organization (WHO) strongly advises researchers, scientists, and the media to use extreme caution in spreading unverified assertions that tobacco or nicotine might lower the risk of COVID-19.
There is not enough evidence available at this time to establish any kind of connection between smoking cigarettes or using nicotine and preventing or treating COVID-19. Nicotine replacement treatments, such as gum and patches, are intended to assist smokers in quitting the habit of using tobacco.
The World Health Organization (WHO) encourages smokers to give up the habit as soon as possible by employing tried-and-true techniques including as toll-free quit lines, mobile text-messaging programs, and nicotine replacement medicines. When you stop smoking, your high heart rate and blood pressure will begin to decline within twenty minutes.
- After a period of 12 hours, the level of carbon monoxide in the bloodstream returns to its usual level;
- In a period of two weeks to twelve weeks, both circulation and lung function will improve;
- After one month to nine months, the coughing and shortness of breath begin to improve;
The World Health Organization (WHO) emphasizes the significance of systematic research that has been ethically sanctioned, is of high quality, and will contribute to the advancement of individual and public health. Furthermore, the WHO stresses that the promotion of unproven interventions may have a detrimental impact on health.
Which types of settings does COVID-19 spread more easily?
On December 23, 2021, the English edition was given a fresh coat of paint. We now understand that the SARS-CoV-2 virus, which may pass from person to person in a number of different ways, is the root cause of the disease.
The evidence that we have right now shows that the virus is most likely to transmit between persons who are in close touch with one another, such as when they are having a discussion with one another.
- When an infected person coughs, sneezes, speaks, sings, or breathes, the virus can disseminate from their mouth or nose in the form of microscopic liquid particles and spread to others;
- When infectious particles that are carried through the air are inhaled at close range by another person, this is often referred to as short-range aerosol transmission or short-range airborne transmission;
Another person can also become infected with the virus if infectious particles come into direct contact with the eyes, nose, or mouth (droplet transmission). The virus is also capable of spreading in interior environments that have inadequate ventilation and/or are congested, both of which are common in places where people prefer to spend more time.
- This is due to the fact that aerosols have the ability to float in the air or travel further than the average distance of a conversation (this is often called long-range aerosol or long-range airborne transmission);
When a person touches their eyes, nose, or mouth after touching surfaces or things that have been contaminated by the virus, they increase their risk of becoming infected with the virus.
More study is being done to get a better understanding of how the virus is spreading, as well as which environments are the most dangerous and why.
Research is also being conducted to investigate newly developing viral variations and the reasons why some viruses are more contagious than others. Please take the time to read the weekly epidemiologic updates for the most recent information on the SARS-CoV-2 variants.
Infected individuals are capable of spreading the virus to others, regardless of whether or not they are exhibiting any symptoms of infection themselves. According to the findings of certain laboratory tests, infected individuals tend to be at their most contagious right before they begin to exhibit symptoms (specifically, two days before they begin to exhibit symptoms), as well as early on in the course of their disease.
People who have serious illness are more likely to remain infectious for a longer period of time. Although it is possible for someone who has never shown signs of having the virus to transmit it on to others, the frequency with which this happens is still unknown, and more study is required in this area.
People who do not exhibit symptoms are referred to by both of these words. People who are infected but never develop any symptoms are referred to as “asymptomatic,” while infected people who have not yet developed symptoms but will go on to develop symptoms in the future are referred to as “pre-symptomatic.” The distinction lies in the fact that people who are infected but have not yet developed symptoms are referred to as “asymptomatic.” Yes, the danger of transmission is increased in any circumstance in which individuals are forced to remain in close quarters with one another for extended periods of time. One helpful approach to think about this is in terms of the “Three C’s.” They describe environments in which the COVID-19 virus is more likely to propagate, including the following:
Congested areas; Close-contact situations, particularly those in which individuals carry on talks very close to one another; places that are confined and enclosed, with little ventilation.
The possibility of COVID-19 becoming widespread is especially high in locations that have characteristics of these “3Cs.” During medical treatments that are collectively referred to as aerosol producing operations, there is an elevated risk of infection in healthcare institutions where patients are having treatment for COVID-19. These have the potential to create very minute droplets that are capable of remaining in the air for extended periods of time and spreading beyond the range of audible speech (typically 1 meter). This is the reason why medical professionals who execute these operations or work in environments where they are performed should adopt special airborne protection precautions.
- Indoor places, particularly those with inadequate ventilation, provide a higher danger than their outside counterparts;
- Singing and heavy breathing during exercise are two examples of activities that can increase the number of particles that are ejected from the mouth and contribute to an increased risk of transmission;
These measures include the use of suitable personal protective equipment such as respirators. In addition to this, visitors are not allowed in the locations where these operations are being carried out because of the potential risks involved. There are a lot of different steps you can take to protect yourself and the people you care about against COVID-19.
- Learn your risks in order to reduce those dangers;
- Observe these essential safety measures:
Follow local guidance: Check to see what recommendations are being made by national, regional, and local authorities so that you get the information that is most pertinent to where you are;
Maintain a safe distance: Maintain a distance of at least one meter from other individuals, even if they don’t appear to have any symptoms of illness, as it is possible for people to be infected with the virus yet not show any signs of illness. Wear a mask: Wear a three-layer mask that fits you properly, especially when you can’t physically isolate yourself from others or when you’re indoors.
It is important to wash your hands before putting on and removing a mask.
Check out our Frequently Asked Questions (FAQs) on Masks and COVID-19, as well as our tutorials on how to wear and construct masks.
A person should stay away from busy areas, indoor settings with low ventilation, and extended interaction with other people.
Spend the most of your time outside rather than within. Ventilation is important: Keep the windows open when you’re inside to let in more of the fresh air outside. When possible, avoid contacting surfaces, especially in public settings or health care institutions, as it is possible that COVID-19-infected persons have touched those surfaces.
Regular cleaning with common disinfectants should be done on all surfaces. You should often wash your hands with soap and water or use a hand massage that contains alcohol. Carry an alcohol-based rub with you at all times and make frequent use of it if you can.
You should cover your coughs and sneezes with your elbow or a tissue, and then immediately toss the used tissue into a container with a lid. After that, you should either wash your hands or apply a hand massage that contains alcohol. Get yourself immunized: Be sure to get vaccinated when it’s your turn.
Regarding immunization, it is important to follow the local instructions and recommendations.

Where did COVID-19 origin?
Transmission of SARS-CoV-1 and SARS-CoV-2 to humans from animals as biological carriers is the virus’s natural reservoir and point of origin. Before the development of SARS-CoV-2 as a pathogen capable of infecting people, there were two earlier zoonosis-based conoravirus outbreaks. These epidemics were caused by SARS-CoV-1 and MERS-CoV, respectively. In the Chinese city of Wuhan, the SARS-CoV2 virus was found to have caused its first known illnesses.
- There is still a lot of mystery around the initial point of viral transmission to humans, as well as the question of when the virus first became pathogenic—before or after the spillover event;
- It has been hypothesized that the Huanan Seafood Market may have been the source of the virus;
This hypothesis is based on the fact that the majority of the early victims were workers at the market. Other study, on the other hand, suggests that tourists could have been the ones to bring the virus into the market, which would have subsequently enabled the virus’s quick spread among customers.
- A report that was convened by the WHO in March 2021 said that the most plausible reason was human spillover via an intermediate animal host, with direct spillover from bats coming in as the next most likely explanation;
It was also speculated that the disease may have been spread through the food supply chain and the Huanan Seafood Market, although this theory was thought to be less plausible. An investigation conducted in November 2021 concluded that the oldest known case had been incorrectly identified, and that the overwhelming majority of early cases that were related to the Huanan Market provided evidence that it was the start of the outbreak.
Rapid evolution is to be anticipated for a virus that was only recently acquired by the transfer of another species. Early instances of SARS-CoV-2 were used to estimate the mutation rate, which was found to be 6.54 times 10-4 per site per year.
In general, coronaviruses have a high level of genetic flexibility; however, the RNA proofreading capabilities of SARS-replication CoV-2’s machinery slows the viral development of the SARS-CoV-2 virus. As a point of reference, it has been discovered that the viral mutation rate in vivo of SARS-CoV-2 is significantly lower than that of influenza.
Research into the natural reservoir of the virus that caused the SARS outbreak from 2002–2004 has led in the identification of several SARS-like bat coronaviruses, the majority of which originate in horseshoe bats.
This finding was made possible by research into the natural reservoir of the virus. The viruses BANAL-52, BANAL-103, and BANAL-236, which were collected in three distinct species of bats in Feuang, Laos, were reported in Nature (journal) in February 2022.
They had a likeness of 96.8% to SARS-CoV-2, which was the level of similarity that was considered to be the closest match. An earlier source that was published in February 2020 determined that the virus known as RaTG13, which was gathered from bats in the city of Mojiang in the province of Yunnan in China, bore a likeness of 96.1 percent to SARS-CoV-2.
None of the aforementioned are a direct ancestor of this one. The horseshoe bat species Rhinolophus sinicus, from which samples were collected, has a similarity to SARS-CoV2 that is 80 percent identical. It is generally agreed that bats are the natural habitat most likely to harbor SARS-CoV2.
- The differences between the SARS-CoV2 and the bat coronavirus imply that humans may have been infected via an intermediate host; nonetheless, the source of the virus’ entry into humans is still unknown;
Although early research suggested that pangolins could play a role as an intermediate host for SARS-like coronaviruses (a study published in July 2020 suggested that pangolins are an intermediate host for SARS-CoV-like coronaviruses), subsequent research has failed to provide evidence that pangolins are responsible for the spillover of the virus.
The fact that pangolin virus samples are too distant to SARS-CoV-2 is evidence against this idea. Isolates collected from pangolins that were apprehended in Guangdong were only 92% similar in sequence to the SARS-CoV-2 genome (matches above 90 percent may sound high, but in genomic terms it is a wide evolutionary gap ).
In addition, despite similarities in a few essential amino acids, samples of pangolin virus demonstrate poor interaction to the human ACE2 receptor. This is the case despite the similarities in certain amino acids.
