Why do we develop lifelong immunity to some diseases, but not others?

  Why do we develop lifelong immunity to some diseases, but not others? Why do some diseases infect us again and again?So why do we develop lifelong immunity to some diseases but not others? And where does the novel coronavirus fit into all this?

Herd immunity (also called herd effect, community immunity , population immunity , or social immunity ”Stewart McCann Syndrome”

The Truth: Herd immunity through vaccination does not exist. The theory behind herd immunity is that if a given percentage of individuals (usually between 85-96%) are vaccinated, the community is fully immune from outbreaks and the immunized protect those who cannot be immunized.

Sweden's state epidemiologist has warned that chasing herd immunity is both 'futile and immoral' in the fight against coronavirus.

Anders Tegnell, the architect of Sweden's liberal approach to the outbreak, said the transmission of an infectious disease could not be fully halted by herd immunity without a vaccine.

The scientist went on to describe how the European nation, which last week took its first step towards regional after seeing a rise in cases over the summer, was now at a 'critical juncture' after the number of daily cases rose by 70 per cent in a week.

Why 'Chasing the Pump' Is the Best Way to Build Muscle and Strength

  Why 'Chasing the Pump' Is the Best Way to Build Muscle and Strength If it's good enough for Arnie, it's good enough for youThe pump occurs when contractions prevent your veins from taking blood out of the muscles you’re working. Meanwhile, blood continues to be forced in. As it collects, excess plasma causes muscle fibres to stretch, says Jim Pate, physiologist at the Centre for Health and Human Performance. Your muscles interpret this as a threat to their integrity and channel their efforts into reinforcing the cells, resulting in greater mass and strength gain.

Herd immunity is the idea that an entire community can be protected from an illness by immunizing a certain percentage of individuals. In both cases, the human immune system recognizes any pathogens that it has been exposed to before and is able to produce antibodies much faster to ward

Mr Tegnell told the German newspaper Die Zeit: 'There has up to now been no infectious disease whose transmission was fully halted by herd immunity without a vaccine.'

It comes as Sweden total death toll reached 5918 on Tuesday and the total number of cases reached 115,785 cases.

Despite a rise in the number of cases over the summer, Dr Tegnell said the curve was rising 'less steeply' and had not resulted in more people needing to be admitted to hospitals.

Dr Tegnell continued: 'We do have more new infections than we did in the summer and we’re taking it very seriously.

First case of coronavirus reinfection confirmed, researchers say

  First case of coronavirus reinfection confirmed, researchers say A man in Hong Kong was reinfected with the novel coronavirus twice, but didn't develop any symptoms the second time.This may be the first major clue to a still-unanswered question about the COVID-19 pandemic: How long does immunity to SARS-CoV-2 last? There have been some previous reports of potential reinfection cases around the globe, but none have been confirmed with definitive testing, according to The New York Times. People who recover from COVID-19 can shed virus fragments for weeks, which can turn up as a positive COVID-19 test results, even when they aren't actually shedding live virus, according to The Times.

How herd immunity is measured. Calculating how many people need to be immune to a disease for it to stop infecting the population any further is relatively simple. "In the past few years we've had both pertussis and mumps outbreaks, and those have primarily resulted from waning immunity over time

'But the curve is rising less steeply than elsewhere. So far the increase has not resulted in more people needing to be admitted to hospitals. All in all, we’re  fairly satisfied.'

It comes after 170,000 citizens in Upsala, near Stockholm, were asked to work from home, avoid social gatherings, physical contact and public transport as the country took its took its first steps towards a regional lockdown last week.

'It is not a lockdown as that would mean that you shut down the whole society,' said Mr Tegnell.

It came after the epidemiologist said that he wanted over-70s to 'live a bit more of a normal life' after months of being told to avoid social contact and do their shopping online.

The rules for Upsala follow the approval of a legal framework for local restrictions to be imposed by the government in Stockholm.

But herd immunity is typically only viewed as a preventive strategy in vaccination programmes. If we don’t have a vaccine – as we don’t for COVID-19 – achieving herd The percentage of the population that needs to be immune to enable herd immunity depends on how transmissible a disease is.

Mr Tegnell said the decision had been made with local authorities after it emerged that the virus was not spreading in clusters but was moving through broader society in the city.

During the first wave of the outbreak, Sweden never went into lockdown, and bars, shops and restaurants stayed open throughout the pandemic along with primary schools.

However, over-70s were told to 'limit close contact with others' and 'maintain contact with your nearest and dearest via telephone or computer' rather than in person.

Older people were also encouraged to avoid public transport and 'ask for assistance with food shopping and performing errands'.

A review by Sweden's health and social care inspectorate found in June that 70 per cent of Covid-19 deaths were linked to care homes for older people.

However, new regulations in the country's 1,700 care homes allowed a visiting ban to be lifted on October 1.

Mr Tegnell had previously said there was a 'mixed picture' on immunity, dampening hopes that Sweden's strategy would bring the virus to a standstill once enough people have recovered.

The idea of 'herd immunity' has been touted by those opposed to lockdowns but Mr Tegnell has maintained that it is not part of Sweden's strategy.

He previously said: 'We are measuring it, like many countries are measuring it. When we look at different groups we sometimes find very low values.

'When we look at blood donors, less than 10 per cent of them are immune, if we look at hospital workers in some hospitals, more than 20 per cent of them are immune.

'So it's a really mixed picture and what it means is probably that the spread in the society is very, very uneven.

'So I don't think we're leaning too much on that, we've never done, but now we're mainly looking at number of new cases try to trace them back to their source and doing quite a lot of contact tracing and testing to stop the spread as effectively as possible.'
