Is the new variant of Coronavirus more dangerous?

Yes and No

The new mutant is more dangerous because it is more easily transmissible from person to person. The new variant is now spreading very rapidly in London and South East of England.

But, so far, the new variant has NOT been found to be more deadly than the original version. The new variant does NOT seem to have substantially increased the risk of hospitalisation and death anymore than the original version of coronavirus.

Emergence of this new mutant (called variant VUI-202012/01 fall) is a certainly a worrying development in this pandemic.

The mutations has made the new strain 70 per cent more transmissible but scientists do not expect these mutations to reduce the effectiveness of vaccines.

Tests are being carried out to confirm that the existing vaccines would still have a high degree of protective affect.

It is an evolving area and we have to hope that the new variant doesn’t make things worse than they are now !

How long can Coronavirus Virus Survive on doors, handles, furniture and fittings?

Coronavirus was previously known to survive for about 3 days at room temperatures. (On certain surfaces made of plastic and stainless steel).

Now an Australian team has found that Coronavirus can survive upto 28 days in Cold conditions. The results need to be interpreted with great caution as it tested virus under unusual artificial conditions and hence might not be relevant for real life situations

On the other hand , if the study is right, then it might indicate that the Pandemic can get worse during cold Winter before it gets better in Spring and Summer.

What can we do? In addition to Social distancing measures and Mask wearing, Frequent hand washing would stop the Virus from Spreading.

Every Week , we are learning more about the Virus. Let’s hope it comes to an end soon.

Can you catch Coronavirus infection from Soft drink cans, Sandwich wrapper and Amazon Parcels?

Yes. Possible but chances are very small according to reports.

If someone sneezed or coughed near a parcel or food package and you touch it within a few hours, it is possible to get Coronavirus infection from parcels and packages.

But, in practice, most parcels and food packaging seem safe and no conclusive real world evidence has been published so far to indicate that packages spread infection widely.

In experimental conditions, Coronavirus has been shown to survive for upto 72 hours. The virus is “more stable on plastic and stainless steel than on copper and cardboard”.

In laboratory conditions “On copper, no viable SARS-CoV-2 virus was measured after 4 hours . On cardboard, no viable SARS-CoV-2 virus was measured after 24 hours”.

In the artificial conditions of the lab “The longest viability of viruses was on stainless steel and plastic; the estimated median half-life of SARS-CoV-2 virus was approximately 5.6 hours on stainless steel and 6.8 hours on plastic”.

Solution: If you are worried , and if possible, you can try leaving parcels for 24hrs before touching them with bare hands. Alternatively, try wearing disposable gloves to remove packaging.

Can weather affect joint pain?

Yes, weather can affect joint pain.

A study involving 2500 people conducted by University of Manchester study showed that “people with arthritis feel more pain on humid days”

The study reports that “Damp and windy days with low pressure can increase risk of experiencing more pain than normal”

Cold, damp days also made pain worse but interestingly pain was not made by temperature alone”.

Other studies in the past have also found a “significant correlation between humidity and pain“.
