COVID-19 New Symptoms: Delta Variant Can Cause Runny Nose And More Issues; Check If You Have Them – TheHealthSite
It is more than 18 months now that the world is in the grip of the deadly coronavirus which has infected millions of people worldwide. As the vaccination drive is taking the lead, there is a new COVID-19 variant that has become a major cause of concern among people. Earlier this month the World Health Organisation declared the rapid spread of the Delta variant which was also a possible reason for the second coronavirus wave in India. This strain which was first identified in India has now mutated to form another highly transmissible variant Delta Plus. At the outset of the pandemic, government agencies and health authorities scrambled to inform people on how to identify symptoms of the virus. However, some common symptoms such as fever, headache, and loss of smell were identified as the warning symptoms of coronavirus infection. But as the virus has evolved, it seems the most common symptoms have changed too.
Beware! New COVID-19 Symptoms Linked To Delta Variant Is Here
Emerging data suggest people infected with the Delta variant the variant possibly behind the spike in the infections in the second wave of COVID-19 around the world are experiencing symptoms different to those we commonly associated with COVID earlier in the pandemic.
Humans are dynamic. With our differences come different immune systems. This means the same virus can produce different signs and symptoms in different ways. A sign is something that’s seen, such as a rash. A symptom is something that’s felt, like a sore throat. The way a virus causes illness is dependent on two key factors:

- Viral factors include things like speed of replication, modes of transmission, and so on. Viral factors change as the virus evolves.
- Host factors are specific to the individual. Age, gender, medications, diet, exercise, health, and stress can all affect host factors.
Common Signs And Symptoms of Delta Variant
As the coronavirus is mutating, the experts have warned that the most common COVID symptoms may have changed from those that were traditionally associated with the virus infection. While fever and cough have always been common COVID symptoms, and headache and sore throat have traditionally presented for some people, a runny nose was rarely reported in earlier data. Meanwhile, loss of smell, which was originally quite common, now ranks ninth.
There are a few reasons we could be seeing the symptoms evolving in this way. It may be because data were originally coming mainly from patients presenting to the hospital who were, therefore, likely to be sicker. And given the higher rates of vaccination coverage in older age groups, younger people are now accounting for a greater proportion of COVID cases, and they tend to experience milder symptoms.
The reason why younger ones could experience milder symptoms of coronavirus infection could be because of the evolution of the virus, and the different characteristics (viral factors) of the Delta variant. But why exactly symptoms could be changing remains uncertain.
While we still have more to learn about the Delta variant, this emerging data is important because it shows us that what we might think of as just a mild winter cold a runny nose and a sore throat could be a case of COVID-19. The reports from the recent research have also highlighted the power of public science. At the same time, we need to remember the results haven’t yet been fully analysed or stratified. That is, “host factors” such as age, gender, other illnesses, medications, and so on haven’t been accounted for, as they would in a rigorous clinical trial. And as is the case with all self-reported data, we have to acknowledge there may be some flaws in the results.
Does COVID-19 Vaccination Affect The Symptoms?
Although new COVID-19 variants can compromise the effectiveness of vaccines, for Delta, the vaccines such as Pfizer and AstraZeneca still appear to offer good protection against symptomatic COVID-19 after two doses. according to the reports, both vaccines have been shown to offer greater than 90% protection from a severe disease requiring hospital treatment.
A recent “superspreader” event in New South Wales highlighted the importance of vaccination. Of 30 people who attended this birthday party, reports indicated none of the 24 people who became infected with the Delta variant had been vaccinated. The six vaccinated people at the party did not contract COVID-19. In some cases, the infection may still possible after vaccination, but it’s highly likely the viral load will be lower and symptoms much milder than they would without vaccination.
Delta Is Spreading Here’s What You Can Do
Evidence indicating Delta is more infectious compared to the original SARS-CoV-2 and other variants of the virus are building. It’s important to understand the environment is also changing. People have become more complacent with social distancing, seasons change, vaccination rates vary all these factors affect the data. But scientists are becoming more confident the Delta variant represents a more transmissible SARS-CoV-2 strain.

Grande Prairie RCMP issued a warning Friday after it was revealed fentanyl linked to a deadly overdose was mixed with a chemical that doesn’t respond to naloxone treatment.
The drugs were initially seized on Feb. 28 after a fatal overdose, and this week, Health Canada reported back to Mounties that the fentanyl had been mixed with Bromazolam, which is a benzodiazepine.
Article content
Mounties say this is the first recorded instance of Bromazolam in Alberta. The drug has previously been linked to nine fatal overdoses in New Brunswick in 2022.
The pills seized in Alberta were oval-shaped and stamped with “20” and “SS,” though Mounties say it can come in other forms.
Naloxone treatment, given in many cases of opioid toxicity, is not effective in reversing the effects of Bromazalam, Mounties said, and therefore, any fentanyl mixed with the benzodiazepine “would see a reduced effectiveness of naloxone, requiring the use of additional doses and may still result in a fatality.”
From January to November of last year, there were 1,706 opioid-related deaths in Alberta, and 57 linked to benzodiazepine, up from 1,375 and 43, respectively, in 2022.
Mounties say officers responded to about 1,100 opioid-related calls for service, last year with a third of those proving fatal. RCMP officers also used naloxone 67 times while in the field, a jump of nearly a third over the previous year.

CFIA continues surveillance for HPAI in cattle, while sticking with original name for disease – RealAgriculture
The Canada Food Inspection Agency will continue to refer to highly pathogenic avian influenza in cattle as HPAI in cattle, and not refer to it as bovine influenza A virus (BIAV), as suggested by the American Association of Bovine Practitioners earlier this month.
Dr. Martin Appelt, senior director for the Canadian Food Inspection Agency, in the interview below, says at this time Canada will stick with “HPAI in cattle” when referencing the disease that’s been confirmed in dairy cattle in multiple states in the U.S.
The CFIA’s naming policy is consistent with the agency’s U.S. counterparts’, as the U.S. Animal and Plant Health Inspection Service has also said it will continue referring to it as HPAI or H5N1.
Appelt explains how the CFIA is learning from the U.S. experience to-date, and how it is working with veterinarians across Canada to stay vigilant for signs of the disease in dairy and beef cattle.
As of April 19, there has not been a confirmed case of HPAI in cattle in Canada. Appelt says it’s too soon to say if an eventual positive case will significantly restrict animal movement, as is the case with positive poultry cases.
This is a major concern for the cattle industry, as beef cattle especially move north and south across the U.S. border by the thousands. Appelt says that CFIA will address an infection in each species differently in conjunction with how the disease is spread and the threat to neighbouring farms or livestock.
Currently, provincial dairy organizations have advised producers to postpone any non-essential tours of dairy barns, as a precaution, in addition to other biosecurity measures to reduce the risk of cattle contracting HPAI.

Canada has seen a concerning rise in measles cases in the first months of 2024.
By the third week of March, the country had already recorded more than three times the number of cases as all of last year. Canada had just 12 cases of measles in 2023, up from three in 2022.
