[7,200 mucormycosis cases reported,
usually in patients with diabetes or compromised immune systems]
The fungal disease, called
mucormycosis, has a 50% mortality rate. It affects patients initially in the
nose but the fungus can then spread into the brain, and can often only be
treated by major surgery removing the eye or part of skull and jaw.
It is usually a rare disease, but
more than 7,200 people in India have now been reported with mucormycosis and
219 have lost their lives. The rise in black fungus infections, mostly in
patients who had severe cases of Covid-19, has been linked to an overuse of
steroids in the treatment of the coronavirus, which can acutely compromise the
immune system if taken over a prolonged period. The high incidence of diabetes
in India has also been blamed, with high blood sugar levels linked to
susceptibility. India has the second highest rate of diabetes in the world.
It has also been reported in Covid
patients who were on ventilators in intensive care units, due to their airways
being exposed to humidity and moisture.
The disease is caused by fungal
spores found in soil and organic matter, usually inhaled by humans from the
air. The mould enters the body and then manifests around the nose and eye
sockets, causing the nose to blacken, and if not stopped will move fatally into
the brain. Healthy individuals will usually fight off the fungus but it can
spread fast in those with compromised immunity.
So far five states, Tamil Nadu,
Odisha, Gujarat, Rajasthan and Telangana, have declared black fungus to be an
epidemic, and more states are expected to follow. The Indian Council of Medical
Research has issued an advisory on the diagnosis and treatment of the disease.
Maharashtra, the first state to be
hit hard by India’s second Covid wave, has already reported upwards of 1,500
cases and 90 deaths, the highest in the country. Hospitals in Delhi have also
begun reported an unprecedented rise in cases – as much 15 to 20 new cases a
day in some hospitals, compared with previous rates of one or two cases a
month. In Delhi and Bangalore, there are now waiting lists for beds for
treatment for the disease.
Dr Amit Thadhani, the director of
Niramaya hospital in Mumbai, said colleagues had begun to see cases of black
fungus in severe Covid patients. “Nearly all patients are diabetic or
immunocompromised,” he said.
The health minister in Delhi,
Satyendar Jain, said on Friday that there were 197 cases of black fungus in
hospitals across the city, and special black fungus wards have now been set up
in the large government hospitals to deal with the influx of patients. Jain
blamed the “very dangerous” misuse of steroids to treat Covid-19 as a cause of
the epidemic.
Balram Bhargava, the director of
the the Indian Council of Medical Research, said of the black fungus: “If a
person’s immunity is suppressed, it will infect them. If the spores have access
to high sugar [levels], it will grow. We have seen this happen with Covid-19
patients with diabetes and uncontrolled sugar, or who are immunocompromised or
have been given immune-suppressants.”
The epidemic is spreading fast. In
Gujarat, there were 371 cases in the state capital, Ahmedabad, and another 400
in Rajkot, a city hit hard by Covid-19. Goa has so far recorded six cases of
mucormycosis. The first case in Kashmir was detected on Friday.
The rise in cases has led to a
shortage of drugs. On Thursday, the Delhi high court told the central
government to procure vital anti-fungal drugs from “wherever it is available in
the world … time is at a premium and so are human lives”. The government said
the shortage was being tackled and more pharmaceutical firms had been granted
approval to produce the injections.
