[New cases have occurred over the past few days in several states.
Providing adequate surveillance and timely treatment over such a large
geographic area is challenging. Fortunately, there is international
help participating in treatment and surveillance. The maps and graphs
in the above report are interesting and provide a good picture of how
the outbreak has progressed over time. They can be accessed at the
above URL.

[2] Ekiti state

The Ekiti State Government has uncovered fresh cases of Lassa fever,
which has claimed 3 lives. The victims were a patient who tested
positive to the disease, and 2 others who had contact with the
deceased.

Commissioner for Health, Rotimi Ojo, who made this disclosure in
Ado-Ekiti yesterday [Tue 13 Mar 2018], said 5 of the 8 other suspected
cases in the state tested negative, one was uncertain and the last was
pending as at press time. He, however, stressed that there was no
cause for alarm, noting that the state government was taking proactive
steps in surveillance activities that would involve all residents due
to some recorded cases and deaths in neighbouring states.

He assured that the State Disease Control team had been activated,
while the process of sensitising the people with jingles, adverts and
other communication media were ongoing. Ojo said similar actions taken
during the 2016 outbreak were successful, adding that the epidemic was
perfectly controlled while the patient, who was properly managed,
survived.

He disclosed that the isolation centre's at Ido Federal Teaching
Hospital, Ido-Ekiti; Oba Adejuyigbe General Hospital and the Ekiti
State University Teaching Hospital, Ado-Ekiti were still operational.
He urged health practitioners, teachers, traditional rulers, religious
leaders, as well as community and opinion leaders to join hands with
the state government to prevent a further spread of the disease in the
state.

Meanwhile, the Cross River State government is set to commission a
pharmaceutical company- CalaPharm that would manufacture drugs for the
treatment of Lassa fever, meningitis and other diseases next month
[April 2018].

The team, which was led by the Commissioner for Information and
Orientation, Mrs. Rosemary Achibong, also visited Rice City and
Industrial Zone, which would house private companies under APZ.

Consultant in charge of the project, Farhan Khan, made this known
yesterday [Tue 13 Mar 2018] in Calabar during inspection of projects
undertaken by the present administration. He said the factory, which
would be of World Health Organisation (WHO) standard would complement
the Governor Ben Ayade Care and also focus on mother and childcare.
Khan said: "Production is coming up soon, so we will be producing
drugs of WHO standards and by next month, it should be commissioned
because the machines are already here."

[Active participation of individual households is essential for
prevention of Lassa fever virus infections. Preventing Lassa virus
transmission requires getting local people to understand that virus
spread to humans occurs when people are in contact with the reservoir
rodent host, the multimammate mouse (in the genus _Mastomys_) or its
excreta; and this can be difficult. Preventing this contact requires
understanding that leads to action. This requires an extensive and
continuous public education effort. Transmission of the virus also
occurs in health facilities when personal protective equipment is not
employed, and barrier-nursing practices are not adequate to protect
staff from blood and secretions of infected patients. Although no
vaccine is available, Ribavirin has been used to successfully treat
patients and is most effective if patients are treated early in the
course of infection.

virus, can be seen at
