Hand hygiene: The best method to prevent infections

July 29, 2010

Infection is defined as lodgment and multiplication of a microorganism in or on the tissues of a host. An infection need not always result in a disease.

Source of infection: Humans (commonest), food and food products, animals and birds, insects, soil, and water.

Mode of spread: Contact (Commonest), inhalation, ingestion, inoculation (injections, blood transfusion), vectors (mosquitoes, flies etc), congenital (from pregnant lady to fetus), iatrogenic (due to medical procedures).

Contact with contaminated surfaces like desk, pens, door handles, tap handles, towels etc. is the easiest way of transmission of infection. Common cold (caused by a virus) is transmitted commonly by contact. Places like School, public places, offices etc. are places where humans can get infected. Even at home coming in contact with contaminated surfaces can spread infection. Infections can spread more effectively by contact than acts like sneezing or coughing. Commonly seen viral conjunctivitis (Madras eye) also spread by contact with contaminated surfaces and not by just seeing someone’s red eye. When a patient with viral conjunctivitis rubs fingers on eyes virus gets carried in hands and when they touch surfaces like table, door handles, towels etc. they can spread disease to those who come in contact with it. However such type of infections can be easily prevented by a simple method, “Hand washing”.

What happens when we cough or sneeze? Aerosols are created in the surroundings. The droplets may contain microbes which will sit on surfaces and hands. When a normal person comes in contact like touching the surfaces, shaking hands etc. the infection will spread to them.

When and how to wash hands? Hand washing must be effective and serve the purpose. Hand washing must be done before and after having food, after acts like sneezing or coughing, nose picking, cleaning ears, using toilet, before and after coming in contact with patients.

For everyday purpose hand washing should be done with clean water with soap. Soaps can be solid soaps and liquid soap. Some soaps are medicated (like dettol, savlon etc). Liquid medicated soaps are ideal for washing hands. Solid soaps have a disadvantage of getting contaminated after long use when multiple people use it. Ordinary soaps act the reducing surface tension and make the microbes and dirt to be washed away. They don’t kill the microbes. Medicated soaps have antiseptics like chlorhexidine, triclosan etc which can kill majority of harmful bacteria, viruses etc. Liquid medicated soaps are highly recommended for washing hands.

Method of washing. First take soap solution, spread on palms, moisten with water, rub the palms, then back of hand, fingers and knuckles, thumbs, finger tips and wrist. Commonly missed areas while washing hands are thumbs, web space & tips of fingers.

While washing hands with soap wash for at least 60 seconds or sing ABCD-Z twice or happy birthday song once in your mind.

Alcohol based hand rubs (containing ethyl alcohol or ethanol 70-80%) are the best. Hand washing with hand rubs takes about 20 seconds. But it’s used commonly in hospitals, clinical laboratories and some food industries. It can be also used at home, but expensive than soap.

Request your doctor to wash hands before examining you or your relative, if he has not done so.

To conclude regular and effective hand washing is the best and the cheapest method of preventing most infections.

Noam Chomsky is one of the leading peace workers in the world. In the wake of America’s attack on Vietnam, he brought out his classic formulation, ‘manufacturing consent’. The phrase explains the state manipulating public opinion to have the public approve of it policies—in this case, the attack of the American state on Vietnam, which was then struggling to free itself from French colonial rule.

In India, we are witness to manufactured hate against religious minorities. This hatred serves to enhance polarisation in society, which undermines India’s democracy and Constitution and promotes support for a Hindu nation. Hate is being manufactured through multiple mechanisms. For example, it manifests in violence against religious minorities. Some recent ghastly expressions of this manufactured hate was the massive communal violence witnessed in Mumbai (1992-93), Gujarat (2002), Kandhamal (2008) and Muzaffarnagar (2013). Its other manifestation was in the form of lynching of those accused of having killed a cow or consumed beef. A parallel phenomenon is the brutal flogging, often to death, of Dalits who deal with animal carcasses or leather.

Yet another form of this was seen when Shambhulal Regar, indoctrinated by the propaganda of Hindu nationalists, burned alive Afrazul Khan and shot the video of the heinous act. For his brutality, he was praised by many. Regar was incited into the act by the propaganda around love jihad. Lately, we have the same phenomenon of manufactured hate taking on even more dastardly proportions as youth related to Hindu nationalist organisations have been caught using pistols, while police authorities look on.

Anurag Thakur, a BJP minster in the central government recently incited a crowd in Delhi to complete his chant of what should happen to ‘traitors of the country...” with a “they should be shot”. Just two days later, a youth brought a pistol to the site of a protest at Jamia Millia Islamia university and shouted “take Azaadi!” and fired it. One bullet hit a student of Jamia. This happened on 30 January, the day Nathuram Godse had shot Mahatma Gandhi in 1948. A few days later, another youth fired near the site of protests against the CAA and NRC at Shaheen Bagh. Soon after, he said that in India, “only Hindus will rule”.

What is very obvious is that the shootings by those associated with Hindu nationalist organisations are the culmination of a long campaign of spreading hate against religious minorities in India in general and against Muslims in particular. The present phase is the outcome of a long and sustained hate campaign, the beginning of which lies in nationalism in the name of religion; Muslim nationalism and Hindu nationalism. This sectarian nationalism picked up the communal view of history and the communal historiography which the British introduced in order to pursue their ‘divide and rule’ policy.

In India what became part of “social common sense” was that Muslim kings had destroyed Hindu temples, that Islam was spread by force, and that it is a foreign religion, and so on. Campaigns, such as the one for a temple dedicated to the Hindu god Rama to be built at the site where the Babri masjid once stood, further deepened the idea of a Muslim as a “temple-destroyer”. Aurangzeb, Tipu Sultan and other Muslim kings were tarnished as the ones who spread Islam by force in the subcontinent. The tragic Partition, which was primarily due to British policies, and was well-supported by communal streams also, was entirely attributed to Muslims. The Kashmir conflict, which is the outcome of regional, ethnic and other historical issues, coupled with the American policy of supporting Pakistan’s ambitions of regional hegemony, (which also fostered the birth of Al-Qaeda), was also attributed to the Muslims.

With recurring incidents of communal violence, these falsehoods went on going deeper into the social thinking. Violence itself led to ghettoisation of Muslims and further broke inter-community social bonds. On the one hand, a ghettoised community is cut off from others and on the other hand the victims come to be presented as culprits. The percolation of this hate through word-of-mouth propaganda, media and re-writing of school curricula, had a strong impact on social attitudes towards the minorities.

In the last couple of decades, the process of manufacturing hate has been intensified by the social media platforms which are being cleverly used by the communal forces. Swati Chaturvedi’s book, I Am a Troll: Inside the Secret World of the BJP’s Digital Army, tells us how the BJP used social media to spread hate. Whatapp University became the source of understanding for large sections of society and hate for the ‘Other’, went up by leaps and bounds. To add on to this process, the phenomenon of fake news was shrewdly deployed to intensify divisiveness.

Currently, the Shaheen Bagh movement is a big uniting force for the country; but it is being demonised as a gathering of ‘anti-nationals’. Another BJP leader has said that these protesters will indulge in crimes like rape. This has intensified the prevalent hate.

While there is a general dominance of hate, the likes of Shambhulal Regar and the Jamia shooter do get taken in by the incitement and act out the violence that is constantly hinted at. The deeper issue involved is the prevalence of hate, misconceptions and biases, which have become the part of social thinking.

These misconceptions are undoing the amity between different religious communities which was built during the freedom movement. They are undoing the fraternity which emerged with the process of India as a nation in the making. The processes which brought these communities together broadly drew from Gandhi, Bhagat Singh and Ambedkar. It is these values which need to be rooted again in the society. The communal forces have resorted to false propaganda against the minorities, and that needs to be undone with sincerity.

Combating those foundational misconceptions which create hatred is a massive task which needs to be taken up by the social organisations and political parties which have faith in the Indian Constitution and values of freedom movement. It needs to be done right away as a priority issue in with a focus on cultivating Indian fraternity yet again.

As democracy is seeping in slowly all over the world, there is an organization which is monitoring the degree of democracy in the individual countries, The Economist Intelligence Unit. As such in each country there are diverse factors which on one hand work to deepen it, while others weaken it. Overall there is a march from theoretical democracy to substantive one. The substantive democracy will herald not just the formal equality, freedom and community feeling in the country but will be founded on the substantive quality of these values. In India while the introduction of modern education, transport, communication laid the backdrop of beginning of the process, the direction towards deepening of the process begins with Mahatma Gandhi when he led the non-cooperation movement in 1920, in which average people participated. The movement of freedom for India went on to become the ‘greatest ever mass movement’ in the World.

The approval and standards for democracy were enshrined in Indian Constitution, which begins ‘We the people of India’, and was adopted on 26th January 1950. With this Constitution and the policies adopted by Nehru the process of democratization started seeping further, the dreaded Emergency in 1975, which was lifted later restored democratic freedoms in some degree. This process of democratisation is facing an opposition since the decade of 1990s after the launch of Ram Temple agitation, and has seen the further erosion with BJP led Government coming to power in 2014. The state has been proactively attacking civil liberties, pluralism and participative political culture with democracy becoming flawed in a serious way. And this is what got reflected in the slipping of India by ten places, to 51st, in 2019. On the index of democracy India slipped down from the score of 7.23 to 6.90. The impact of sectarian BJP politics is writ on the state of the nation, country.

Ironically this lowering of score has come at a time when the popular protests, the deepening of democracy has been given a boost and is picking up with the Shaheen Bagh protests. The protest which began in Shaheen Bagh, Delhi in the backdrop of this Government getting the Citizenship amendment Bill getting converted into an act and mercilessly attacking the students of Jamia Milia Islamia, Aligarh Muslim University along with high handed approach in Jamia Nagar and neighbouring areas.  From 15th December 2019, the laudable protest is on.

It is interesting to note that the lead in this protest has been taken by the Muslim women, from the Burqa-Hijab clad to ‘not looking Muslim’ women and was joined by students and youth from all the communities, and later by the people from all the communities. Interestingly this time around this Muslim women initiated protest has contrast from all the protests which earlier had begun by Muslims. The protests opposing Shah Bano Judgment, the protests opposing entry of women in Haji Ali, the protests opposing the Government move to abolish triple Talaq. So far the maulanas from top were initiating the protests, with beard and skull cap dominating the marches and protests. The protests were by and large for protecting Sharia, Islam and were restricted to Muslim community participating.

This time around while Narendra Modi pronounced that ‘protesters can be identified by their clothes’, those who can be identified by their external appearance are greatly outnumbered by all those identified or not identified by their appearance.

The protests are not to save Islam or any other religion but to protect Indian Constitution. The slogans are structured around ‘Defence of democracy and Indian Constitution’. The theme slogans are not Allahu Akbar’ or Nara-E-Tadbeer’ but around preamble of Indian Constitution. The lead songs have come to be Faiz Ahmad Faiz’s ‘Hum Dekhenge’, a protest against Zia Ul Haq’s attempts to crush democracy in the name of religion. Another leading protest song is from Varun Grover, ‘Tanashah Aayenge…Hum Kagaz nahin Dikhayenge’, a call to civil disobedience against the CAA-NRC exercise and characterising the dictatorial nature of the current ruling regime.

While BJP was telling us that primary problem of Muslim women is Triple talaq, the Muslim women led movements has articulated that primary problem is the very threat to Muslim community. All other communities, cutting across religious lines, those below poverty line, those landless and shelter less people also see that if the citizenship of Muslims can be threatened because of lack of some papers, they will be not far behind in the victimization process being unleashed by this Government.

While CAA-NRC has acted as the precipitating factor, the policies of Modi regime, starting from failure to fulfil the tall promises of bringing back black money, the cruel impact of demonetisation, the rising process of commodities, the rising unemployment, the divisive policies of the ruling dispensation are the base on which these protest movements are standing. The spread of the protest movement, spontaneous but having similar message is remarkable. Shaheen Bagh is no more just a physical space; it’s a symbol of resistance against the divisive policies, against the policies which are increasing the sufferings of poor workers, the farmers and the average sections of society.

What is clear is that as identity issues, emotive issues like Ram Temple, Cow Beef, Love Jihad and Ghar Wapasi aimed to divide the society, Shaheen Bagh is uniting the society like never before. The democratisation process which faced erosion is getting a boost through people coming together around the Preamble of Indian Constitution, singing of Jan Gan Man, waving of tricolour and upholding the national icons like Gandhi, Bhagat Singh, Ambedkar and Maulana Azad. One can feel the sentiments which built India; one can see the courage of people to protect what India’s freedom movement and Indian Constitution gave them.

Surely the communal forces are spreading canards and falsehood against the protests. As such these protests which is a solid foundation of our democracy. The spontaneity of the movement is a strength which needs to be channelized to uphold Indian Constitution and democratic ethos of our beloved country.

In Minneapolis, US an African American, George Floyd lost his life as the white policeman, Derek Chauvin, caught hold of him and put his knee on his neck. This is a technique developed by Israel police. For nine long minutes the knee of the while policeman was on the neck of George, who kept shouting, I can’t breathe.

Following this gruesome murder America erupted with protests, ‘Black lives matter’. The protestors were not just African Americans but also a large section of whites. Within US one police Chief apologized for the act of this. In a touching gesture of apology the police force came on its knees. This had reverberations in different parts of the World.

The act was the outcome of the remnants of the racial hatred against blacks by the whites. It is the hatred and the perceptions which are the roots of such acts of violence. What was also touching that the state of democracy in US is so deep that even the police apologized, the nation, whites and blacks, stood up as a sensitive collective against this violence.

US is not the only country where the brutal acts of violence torment the marginalized sections of society. In India there is a list of dalits, minorities and adivasis who are regularly subjected to such acts. But the reaction is very different. We have witnessed the case of Tabrez Ansari, who was tied to the pole by the mob and beaten ruthlessly. When he was taken to police station, police took enough time to take him to hospital and Tabrez died.

Mohsin Sheikh, a Pune techie was murdered by Hindu Rashtra Sena mob, the day Modi came to power in 2014. Afrazul was killed by Shambhulal Regar, videotaped the act released on social media. Regar believed that Muslims are indulging in love Jihad, so deserve such a fate. Mohammad Akhlaq is one among many names who were mob lynched on the issue of beef cow. The list can fill pages after pages.

Recently a young dalit boy was shot dead for the crime of entering a temple. In Una four dalits were stripped above waste and beaten mercilessly. Commenting on this act the Union Minister Ramvilas Paswan commented that it is a minor incident. Again the list of atrocities against dalits is long enough. The question is what Paswan is saying is the typical response to such gruesome murders and tortures. In US loss of one black life, created the democratic and humane response. In India there is a general silence in response to these atrocities. Some times after a good lapse of time, the Prime Minister will utter, ‘Mother Bharati has lost a son’. Most of the time victim is blamed. Some social groups raise their voice in some fora but by and large the deafening silence from the country is the norm.

India is regarded as the largest democracy. Democracy is the rule of law, and the ground on which the injustices are opposed. In America though the present President is insensitive person, but its institutions and processes of democratic articulations are strong. The institutions have deepened their roots and though prejudices may be guiding the actions of some of the officers like the killer of George, there are also police officers who can tell their President to shut up if he has nothing meaningful to say on the issue. The prejudices against Blacks may be prevalent and deep in character, still there are large average sections of society, who on the principles of ‘Black lives matter’. There are large sections of vocal population who can protest the violation of basic norms of democracy and humanism.

In India by contrast there are multiple reasons as to why the lives of Tabrez Ansari, Mohammad Akhlaq, Una dalit victims and their likes don’t matter. Though we claim that we are a democracy, insensitivity to injustices is on the rise. The strong propaganda against the people from margins has become so vicious during last few decades that any violence against them has become sort of a new normal. The large populace, though disturbed by such brutalities, is also fed the strong dose of biases against the victims. The communal forces have a great command over effective section of media and large section of social media, which generates Hate against these disadvantaged groups, thereby the response is muted, if at all.

As such also the process of deepening of our democracy has been weak. Democracy is a dynamic process; it’s not a fixed entity. Decades ago workers and dalits could protest for their rights. Now even if peasants make strong protests, dominant media presents it as blocking of traffic! How the roots of democracy are eroded and are visible in the form where the criticism of the ruling dispensation is labelled as anti National..

Our institutions have been eroded over a period of time, and these institutions coming to the rescue of the marginalized sections have been now become unthinkable. The outreach of communal, divisive ideology, the ideology which looks down on minorities, dalits and Adivasis has risen by leaps and bounds.

The democracy in India is gradually being turned in to a hollow shell, the rule of law being converted in to rule of an ideology, which does not have faith in Indian Constitution, which looks down upon pluralism and diversity of this country, which is more concerned for the privileges of the upper caste, rich and affluent. The crux of the matter is the weak nature of democracy, which was on way to become strong, but from decades of 1980s, as emotive issues took over, the strength of democracy started dwindling, and that’s when the murders of the types of George Floyd, become passé. One does complement the deeper roots of American democracy and its ability to protect the democratic institutions, which is not the case in India, where protests of the type, which were witnessed after George Floyd’s murder may be unthinkable, at least in the present times.
