the Delta variant at the origin of the new explosion of cases?

From June 30 to July 7, 2021, Senegal recorded 1,308 new cases. For the day of Wednesday, July 1 alone, that is to say today, 356 contaminations were identified out of 2,388 tests carried out. However, the number of cases did not exceed 2,095 from June 1 to 30. The previous month, namely from May 1 to June 1, there was less contamination, precisely 1,045, that is to say less than what was observed this week. Simply alarming!

But the situation is likely to get worse if nothing is done to reverse the trend. During the meeting of the National Epidemic Management Committee, Professor Moussa Seydi alerted the public to the fact that more and more young people without comorbidities are presenting serious forms.

The Senegalese scientist, responsible for medical care, insisted a lot on vaccination against the circulation of variants. Most worrying, Delta is unfortunately present in Senegal.

Delta reported in Senegal

In Senegal, this variant was detected by the Pasteur Institute in Dakar (IPD) and the Institute for Health Research, Epidemiological Surveillance and Training (IRESSEF).

From April to May 2021, the IPD claims to have carried out a sampling of outgoing travelers. Thus, out of a total of 275 sequenced samples, the Nigerian variant was identified in the majority of samples, i.e. 95 cases, or 35%), followed by the British variant known as Alpha with 63 cases, or 23%.

The same press release informs that a new case of the South African variant was detected while the analyzes made it possible to identify the Indian variant called Delta in two foreign travelers. In addition to these known variants, 10 other lines have been detected by the Institut Pasteur in Dakar.

“To date, 900 samples have been sequenced with 300 SARS-COV-2 positive samples from the first wave and 600 positive SARS-COV-2 samples from the second wave.

Regarding the first wave, no variant of concern was identified. Regarding the second wave, we found a greater variability of the virus with 30 different variants with 10% of the strains consisting of so-called worrying variants ”, for his part, Professor Souleymane Mboup informed, according to whom, 95% of these variants found are of the Alpha class better known under the nickname of Briton while 5% belong to the family of the Indian variant or Delta.

As a result, these two reference laboratories insisted on respecting the barrier measures but above all on the need to vaccinate as many people as possible to protect themselves from a third wave in Senegal.

60% more contagious than the British variant

Appeared for the first time in India, it is 60% more contagious than the English variant. According to euronews read in Dakaractu, this variant would include mutations allowing the new coronavirus to attach more easily to the cells of our body.

Another concern is related to the symptoms that are specific to it. Professor Tim Spector who leads the Zoe COVID Symptom Study in the UK has revealed that for the Delta variant, the dominant symptoms are headache and runny nose. In young people, the scientist makes it known that the disease presents itself in the form of a “bad cold”.

According to the World Health Organization (WHO), the Delta variant has been identified in 16 countries, 9 of which are experiencing an increase in cases.

In Africa, this new variant is present in 3 of the 5 countries where contamination has experienced a worrying increase on June 27.

In the Democratic Republic of the Congo where the third wave has settled since last May, the Delta variant dominates in 79% of the samples while in Uganda it is seen in at least 97% of the samples.
