Haven’t had Covid yet? It could be more than just luck

Covid, who have somehow managed to avoid testing positive.

The simplest explanation is that these people have never come into contact with the virus, a report by The Conversation said.  And, this could be because such people have been shielded during the pandemic.

A theory around why certain people have avoided infection is that, although they are exposed to the virus, it fails to establish an infection even after gaining entry to the airways. This could be due to a lack of the receptors needed for SARS-CoV-2 to gain access to cells.

Once a person does become infected, differences in the immune response to SARS-CoV-2 play a role in determining the severity of symptoms. It is possible that a quick and robust immune response could prevent the virus from replicating to any great degree in the first instance, researchers said.

The efficacy of our immune response to infection is largely defined by our age, lifestyle and genetics.

Scientists studying the underlying causes of severe Covidhave identified a genetic cause in nearly 20% of critical cases. Just as genetics could be one determining factor of disease severity, our genetic makeup may also hold the key to resistance to SARS-CoV-2 infection.

There’s also the possibility that previous infection with other types of coronaviruses results in cross-reactive immunity. This is where our immune system may recognise SARS-CoV-2 as being similar to a recent invading virus and launch an immune response. Seven coronaviruses infect humans: four that cause the common cold, and one each that causes Sars (severe acute respiratory syndrome), Mers (Middle East respiratory syndrome), and COVID.

How long-lasting this immunity maybe is another question. Seasonal coronaviruses that

New video of Vladimir Putin twisting toes and heels sparks more health rumours
Vladimir Putin fidgeting his feet has sparked more health fear of the despot's health.The Russian despot was meeting with Tajikistan's President Emomali Rahmon yesterday (Monday, May 16) to discuss the trade and commercial connections between the two countries.During the televised rendezvous as shared by Russian media, the 69-year-old Russian leader is seen erratically moving his left foot and twisting his toes and heels while talking to Rahmon.The unusual behaviour is also spotted by Rahmon, who can be seen looking down at Putin during his odd foot movement. Putin keeps his right arm on the chair while keeping his left hand on his lap.Rumours over Putin's deteriorating health have strengthened in recent months.Last month, the Russian president was seen shaking his hands "uncontrollably" when he met his close ally, Belarus' leader Alexander Lukashenko.During a meeting with his defence minister Sergei Shoigu, Putin also appeared unwell as he gripped the corner of the desk throughout the entire session and appeared to be slightly slumped in his chair.People on social media also noticed a change in Putin's physical appearance, describing him as "ashen and bloated".One Royal Navy admiral claimed the president, 69, may have cancer.Retired Royal Navy Admiral Chris Parry said: "He has been using these very long tables to interview people."I think his immune system might be suppressed at the moment.
