WHAT IS THE DELTA VARIANT OF COVID?

Delta variant is a newly mutated variant of SARS-CoV-2 (the virus responsible for COVID in man). It is named as B.1.617.2 (Delta). This variant came out in India and get widely spread and is potentially transmitted faster than other variants. 



HOW MUTATION OCCUR IN COVID 19?

It has mutations in the gene encoding the SARS-CoV-2 spike protein causing the substitutions T478K, P681R and L452R (different variants of COVID 19), which affects the ability of a virus of getting transmitted as well as the extent of affect of antibodies on it. 


HOW DO VARIANTS OCCUR?

The genome (genetic information) of virus is packed inside an envelope that contains proteins, including the spike protein.


Mutations are changes in the genetic code of a virus that naturally occur over time when an animal or person is infected. Many mutations do not affect the virus’s ability to spread or cause disease because they do not alter the major proteins involved in infection; however becoming a virulent (extremely severe or harmful) strain depends upon the virus, whether the mutation is beneficial for the virus or not.


HOW MANY CONFIRMED CASES OF DELTA VARIANT OF COVID-19 ARE REPORTED BY DIFFERENT COUNTRIES?


WHEN AND WHERE DID THE FIRST OUTBREAK OF COVID-19 DELTA VARIANT WAS REPORTED?

During 15th April & 3rd May 2021, 21 laboratories confirmed 47 B.1.617.2 cases that emerged from a gymnastics facility of Oklahoma, US and and  26 epidemiologically linked cases. The household attack rates were 53%, respectively.


WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?

In indoor sports settings and households the B.1.617.2 variant is highly transmissible. Vaccination and reduce the spread of SARS-COV-2 among people in indoor sports and their contacts.

According to CDC, all eligible persons, including athletes and athletic staff members, should receive COVID-19 vaccination, especially those engaging in strenuous sports with limited ability to maintain physical distancing. In addition, multicomponent prevention strategies (e.g., testing, symptom monitoring, and other setting-specific measures) remain important to reduce SARS-CoV-2 transmission among persons participating in indoor sports and their contacts.


WHAT ARE THE RISK FACTORS?

According to CDC,

    1. Not to use treatment or follow treatment recommendations of being quarantine and testing guidance

    2. Ignoring minor symptoms and delayed recognition of infection or confusing the symptoms to other causes.

    3. Not using masks among active participants.

    4. Coupled with increased respiration during active sport participation (further, facility A policy was that all persons not actively participating wear masks, but this policy was not always observed). 

    5. Poor facility ventilation; staff members training multiple cohorts; low COVID-19 vaccination coverage among participants (partly related to age eligibility).

    6. Inadequate cleaning of high-touch surfaces between participant use.

    7. Overlapping cohort practice times, facilitating transmission between cohorts. 




WHAT ARE THE SYPMTOMS OF COVID 19?

    Most common symptoms:

    1. Fever

    2. Dry cough

    3. Tiredness

    Less common symptoms:

    1. Aches and pains

    2. Sore throat

    3. Diarrhoea

    4. Conjunctivitis

    5. Headache

    6. Loss of taste or smell

    7. Rash on skin, or discoloration of fingers or toes



WHAT ARE THE PRECAUTIONS FOR THE DELTA VARIANT?

    1. Don't go outside without any essential work

    2. Don't forget to wear double mask

    3. Maintain social distancing

    4. Sanitize and disinfect things

    5. Wash your hands with soap

    6. The most important thing is to get vaccinated as soon as possible
