Covid-19 Widespread and the Fears of Fourth Wave

Some countries are reporting more new coronavirus cases compared with the ratio of few previous weeks. Global data trends show that the Covid 19 pandemic is not over yet. Recently, Moscow reported highest death toll of any Russian city, while Delta variant forced strict restrictions in the Asia-Pacific region as well as many other parts of the world. With gradually transmissible COVID-19 variants including the delta and delta plus variants and the novel lambda variant becoming more widespread and wavering vaccination campaigns, many places around the world are undergoing renewed outbreaks.

Recently, Southern African country of Namibia documented the maximum average rate of infections in the world. This wave of covid 19 in Namibia is the deadliest and has been driven by the delta variant as per the media reports. In Thailand, coronavirus cases and deaths have more than doubled. The health care system is under immense pressure after the increased demand. About 90% of Thailand’s cases and deaths have come since April a tenfold surge. Pakistan has also seen surge in positive cases. Prime Minister Imran Khan warned of a forthcoming fourth wave of Covid-19 in the country, naming the Delta variant, which is supposed to have originated in India, as the prime concern. The world has been in pandemic mode for a year and a half. The virus continues to spread at a slow burn; intermittent lockdowns are the new normal. The pandemic is not moving ahead in the same way from place to place. Countries such as China, New Zealand have reached a low level of cases after lockdowns of different lengths and are easing restrictions. To another places, such United States and Brazil, Bangladesh, India cases are increasing fast after governments lifted lockdowns rapidly or never started them nationwide. This pandemic also have psychological impacts. The hazard of infection can twist our psychological reactions to ordinary interactions, leading us to behave in surprising ways.

A person can develop immunity, which is the capability to fight infection in two ways.  Either after being infected with a virus or by being vaccinated. However, immune protection is not always identical. Vaccine immunity and natural immunity for SARS–CoV–2 can vary in terms of the forte of the immune response or the extent of time that the defense lasts. Furthermore, not everyone will get the same level of immunity from infection, while immune reactions to the vaccines are very reliable. The dissimilarity in immune response between vaccination and infection appears to be even bigger when dealing with new variants. In early July, two new studies were printed that show COVID-19 vaccines, though somewhat less actual than they are against the older strains of the virus, still appear to deliver outstanding immune response against the new variants. Researchers looked at how antibodies fix to new variants of the coronavirus and found that people who were formerly infected with coronavirus might be vulnerable to the new strains, while people who were vaccinated were more likely to be safe. COVID-19 vaccines offer a benign and steadfast path to immunity against both the older strains of coronavirus and against developing strains, particularly the new delta variant.
