As the world marks tuberculosis (TB) day tomorrow, one of the things animal health specialists will be discussing is how to curb the spread of the disease from animals to human.

Bovine TB, which affects animals, remains a serious threat to livestock and human health.

The World Organisation for Animal Health (WOAH) notes that the chronic respiratory disease is caused by a bacteria called Mycobacterium bovis (M. bovis), which is closely related to the bacteria that causes human tuberculosis (M. tuberculosis)

Bovine TB is a zoonotic disease, which means that it can be naturally transmitted between animals and humans.

However, it is more serious and harder to treat than human tuberculosis. This is because the bacteria is resistant to the antibiotic pyrazinamide used to treat human TB.

Dr Joseph Mugachia, a veterinarian at the Garden Veterinary Services in Nairobi, says Bovine TB is an infectious disease among cattle and affects other domesticated animals, and certain wildlife populations.

It causes persistent coughing, bleeding through the nose or mouth, nodules of the skin and udder (at advance stage of illness) and eventually death.

He says that the infectious Bovine TB is not treatable in cows. “TB is a neglected disease whose diagnosis and control is not given much attention. The emphasis is only at the slaughterhouse when checking the safety of meat for consumption,” says Dr Mugachia.

He adds that the disease is not treatable because the risk analysis on cost, time and spread shows that it is not practicable to treat.

“It is too expensive because cows have bigger mass than human hence need more drugs. It takes too long to treat, which increases the risk of transmission to humans and other animals. The best thing, therefore, is to destroy the affected animals.”

INHALING DROPLETS FROM COUGHS OR SNEEZES

In dogs and cats, Dr Mugachia says skin reaction test and X-rays are used to detect the disease. “In cattle, we use only the skin reaction test. The reason being X-ray is logistical difficulty in cattle due to large body mass which is poorly penetrable by the rays.”

Animals too can get infected with human TB and that chicken TB can also affect both cows and humans and vice versa, he offers.

Dr Dave Muthama, who deals with human TB at the Elizabeth Glaser Pediatric AIDS Foundation, says that Bovine TB in human is treatable, just like the ordinary type, through a combination of antibiotics that kill the Mycobacterium bovis bacteria.

However, one complication is that M. bovis is always resistant to the TB drug pyrazinamide, although other first line TB drugs can still be used.

And like the human disease, Bovine TB is spread through inhaling tiny droplets from the coughs or sneezes of an infected animal or person and through contaminated food, making it gradually a greater threat to human health than previously thought.

It mainly affects the lungs, but it can also affect any part of the body, including the abdominal glands, bones and nervous system.

In human, its symptoms include fever, night sweats, persistent cough, diarrhoea, weight loss and abdominal pain.

According to the World Health Organisation (WHO), of the things that makes it difficult to know how much human disease is caused by M. bovis is because most commonly used laboratory processes can’t distinguish between M. bovis and M. tuberculosis.

The organisation further notes that the true burden of zoonotic TB is likely to be underestimated due to lack of routine surveillance data from most countries.

Dr Muthama, however, says that with advance in technology, it is possible to detect the rare forms of TB using gene expert tests.

“Gene expert test is like looking at the DNA of the organisms. We have found out that these rare forms of TB are in small proportion among human beings.”

In 2016, there were an estimated 147,000 new cases of zoonotic TB in people globally, and 12,500 deaths due to the disease with most developed countries recording a much smaller number of cases of TB caused by M. bovis in humans, according to WHO.

Africa is the highest hit with an incidence of 71,000 and mortality of 9,270. It is followed by South East Asia with 44,900 incidences against 2,090 deaths. Western Pacific is third with 10,000 incidences and 309 death.

In 2018, Kenya listed Bovine TB among the 36 priority zoonoses diseases to be tackled. Others were anthrax, brucellosis, avian influenza and other pandemic influenza viruses and plague.

According to Dr Mugachia, the best way to save both humans and livestock from Bovine TB is to control its spread.

“I would advise that animals in high risk areas be tested for TB. Animals should be housed with good air circulation and people who are suspected to have TB should be tested and treated as soon as possible to avoid spreading it to the livestock,” says Dr Mugachia.

High risk areas, he says, are arid and semi-arid, and places like Kiambu, Vihiga and Kisii where families live close to animals due to small acreages of land.

He adds that whenever TB is diagnosed on the farm, milk should be tested to rule out contamination.

Cattle can spread Bovine TB to other cattle directly via respiratory route, via infected milk, during birth through the placenta and contamination of grazing areas or natural water sources.

Others measures outlined in the document include the provision of personal protective equipment to staff, provision of sanitizers and access to washing facilities fitted with soap and water, temperature checks for all staff and clients entering public offices regular fumigation of office premises and vehicles and minimizing of visitors except by prior appointments.
Officers who contract the virus and come back to work after quarantine or isolation period will be required to follow specific directives such as obtaining clearance from the isolation facility certified by the designated persons indicating that the public officer is free and safe from Covid-19. The officer will also be required to stay away from duty station for a period of seven days after the date of medical certification.
“The period a public officer spends in quarantine or isolation due to Covid-19, shall be treated as sick leave and shall be subject to the Provisions of the Human Resource Policy and procedures Manual for the Public Service(May,2016),” read the document.
The service has also made discrimination and stigmatization an offence and has guaranteed those affected with the virus to receive adequate access to mental health and psychosocial supported offered by the government.
The new directives targeting the Public Services come at a time when Kenyans have increasingly shown lack of strict observance of the issued guidelines even as the number of positive Covid-19 cases skyrocket to 13,771 and leaving 238 dead as of today.

Globally, one in four people is affected by mental or neurological disorders at some point in their lives, this is according to the WHO.

Currently, around 450 million people suffer from such conditions, placing mental disorders among the leading causes of ill-health and disability worldwide.

The pandemic has also been known to cause significant distress, mostly affecting the state of one’s mental well-being.

With the spread of the COVID-19 pandemic attributed to the novel Coronavirus disease, millions have been affected globally with over 14 million infections and half a million deaths as to date. This has brought about uncertainty coupled with difficult situations, including job loss and the risk of contracting the deadly virus.

In Kenya the first Coronavirus case was reported in Nairobi by the Ministry of Health on the 12th March 2020.  It was not until the government put in place precautionary measures including a curfew and lockdown (the latter having being lifted) due to an increase in the number of infections that people began feeling its effect both economically and socially.

A study by Dr. Habil Otanga,  a Lecturer at the University of Nairobi, Department of Psychology says  that such measures can in turn lead to surge in mental related illnesses including depression, feelings of confusion, anger and fear, and even substance abuse. It also brings with it a sense of boredom, loneliness, anger, isolation and frustration. In the post-quarantine/isolation period, loss of employment due to the depressed economy and the stigma around the disease are also likely to lead to mental health problems.

The Kenya National Bureau of Statistics (KNBS) states that at least 300,000 Kenyans have lost their jobs due to the Coronavirus pandemic between the period of January and March this year.

KNBC noted that the number of employed Kenyans plunged to 17.8 million as of March from 18.1 million people as compared to last year in December. The Report states that the unemployment rate in Kenya stands at 13.7 per cent as of March this year while it stood 12.4 per cent in December 2019.

Mama T (not her real name) is among millions of Kenyans who have been affected by containment measures put in place to curb the spread of the virus, either by losing their source of income or having to work under tough guidelines put in place by the MOH.

As young mother and an event organizer, she has found it hard to explain to her children why they cannot go to school or socialize freely with their peers as before.

“Sometimes it gets difficult as they do not understand what is happening due to their age, this at times becomes hard on me as they often think I am punishing them,”

Her contract was put on hold as no event or public gatherings can take place due to the pandemic. This has brought other challenges along with it, as she has to find means of fending for her family expenditures that including rent and food.

“I often wake up in the middle of the night with worries about my next move as the pandemic does not exhibit any signs of easing up,” she says. She adds that she has been forced to sort for manual jobs to keep her family afloat.

Ms. Mary Wahome, a Counseling Psychologist and Programs Director at ‘The Reason to Hope,’ in Karen, Nairobi says that such kind of drastic life changes have an adverse effect on one’s mental status including their family members and if not addressed early can lead to depression among other issues.

“We have had cases of people indulging in substance abuse to deal with the uncertainty and stress brought about by the pandemic, this in turn leads to dependence and also domestic abuse,”

Sam Njoroge , a waiter at a local hotel in Kiambu, has found himself indulging in substance abuse due to challenges he is facing after the hotel he was working in was closed down as it has not yet met the standards required by the MOH to open.

“My day starts at 6am where I go to a local pub, here I can get a drink for as little as Sh30, It makes me suppress the frustration I feel.” he says.

Sam is among the many who have found themselves in the same predicament and resulted to substance abuse finding ways to beat strict measures put in place by the government on the sale of alcohol so as to cope.

Mary says, situations like Sam’s are dangerous and if not addressed early can lead to serious complications, including addiction and dependency, violent behavior and also early death due to health complications.

She has, however, lauded the government for encouraging mental wellness and also launching the Psychological First Aid (PFA) guide in the wake of the virus putting emphasis on the three action principal of look, listen and link. “When we follow this it will be easy to identify an individual in distress and also offer assistance”.

Mary has urged anyone feeling the weight of the virus taking a toll on them not to hesitate but look for someone to talk to.

“You should not only seek help from a specialist but also talk to a friend, let them know what you are undergoing and how you feel, this will help ease their emotional stress and also find ways of dealing with the situation they are facing,” She added

Mary continued to stress on the need to perform frequent body exercises as a form of stress relief, reading and also taking advantage of this unfortunate COVID-19 period to engage in hobbies and talent development.

“Let people take this as an opportunity to kip fit, get in touch with one’s inner self and  also engage in   reading that would  help expand their knowledge.
