Introduction:

Enteroviruses are common viruses which cause

a variety of symptoms ranging from mild illness, such as fever,

rash, and cold-like symptoms, to more severe conditions, such as

viral meningitis or encephalitis. Non-polio enteroviruses (EV) are

a group of ssRNA viruses with over 100 different serotypes. They

are the major aetiological agent of childhood meningitis as well as,

rarely, encephalitis and acute flaccid paralysis

[1,2] .

Methods:

In-house PCR is used for the detection of

enteroviruses (including polioviruses) and parechoviruses in

faeces, throat swabs, CSF and blood specimens. All significant

enterovirus or parechovirus positive results (i.e. detected in CSF

or with significant symptoms) are recommended to be submitted

for typing. All EV PCR positive CSF, faecal and throat swab isolates

were typed by sequencing of VP1 or VP4

[3] .

Epidemiological

information and typing data were compared for the specimens

received in the 24 month period between 1st January 2013 and

31st December 2015.

Results:

A total of 329 specimens, representing 315 patients,

were submitted to the laboratory for typing between 1st January

2013 and 31st December 2015. The majority of samples were

cerebrospinal fluid samples (66%) or throat swabs (19%). Age and

gender data was available for >99% of the cases. Thirty-nine per-

cent of the cases were female. Median age of patients was 1 month

(range: 16 days–81 years)

.

Interestingly, half of the samples were

from patients <1 year old. Typing results were available for 80% of

all samples. Twenty-seven different EV serotypes were detected.

The commonest enterovirus types were coxsackievirus B5 (12.8%),

echovirus 6 (12.1%), echovirus 30 (5.5%), coxsackievirus A6 (5.5%)

and Echovirus 9 (4.0%). Distinct seasonality of enterovirus was

observedwith peaks of infection occurring in September 2013, June

2014 and October 2015. Most notable was the predominance of

Echovirus 6 and Coxsackievirus B5 in autumn 2015.

Discussion:

EV surveillance is important not only for monitor-

ing the changing epidemiology of these infections but also for the

rapid identification of spread of emerging EV. In Europe within the

last decade, echovirus 30was the cause of themajority of outbreaks

associatedwith CNS infections

[4] . I

n 24months of enterovirus typ-

ing in Scotland we have identified peaks of infection predominated

by echovirus 6 and coxsackievirus B5 in autumn 2015.

Ebola virus outbreak in West Africa –

Portuguese laboratory response overview

and Biopreparedness Unit, Department of Infectious

Diseases, Portugal

The Ebola outbreak inWest Africawas the largest andmost com-

plex outbreak since the virus was discovered in 1976. First cases

were notified in March of 2014 and the last ones were reported in

April of 2016 in Liberia.

To respond to the epidemic of Ebola virus, Portugal cre-

ated an coordination committee where the National Institute of

Health, through the Emergency Response and Biopreparedness

Unit (UREB), participated integrating the “Platform Response to

Ebola Virus Disease”.

This unit is the national reference laboratory for biological

events or catastrophes and has skilled professionals, know-how,

BSL-3 facilities, capacity to work 24 h/7 d and trained human

resources to increase lab capacity in emergency situations. The lab-

oratory diagnosis capacity includes the detection of bacteria, virus

and toxins, which are considered bioterrorism agents, using Micro-

biology, Immunology and Molecular Biology techniques. In order

to ensure quick and reliable results, a laboratory algorithm was

developed taking in account the available human and technical

resources. UREB also participates regularly in International Exter-

nal Quality Assessments, training courses and simulation exercises.

Although Portugal does not have a BSL-4 facility, the partici-

pation in European projects as QUANDHIP, allowed the upgrade

of Biosafety procedures, technical skills and the use of a glove con-

tainer for samples inactivation permitting the analysis of suspected

samples, avoiding the need to send suspected samples to abroad.

In Portugal 15 samples from suspected cases concerning

patients who were traveling from African countries were received

at UREB. All samples were negative for Ebola virus, and the dif-

ferential diagnosis was performed in parallel which includes the

detection of

Plasmodium

spp., Marburg and Lassa virus. Forty per-

cent of suspected cases were positive for

Plasmodium falciparum

.

The algorithmof laboratory procedures for samples suspected to

Ebola virus it was well implemented and was several times tested

through the participation in simulation exercises. The communica-

tion of the results to the competent authorities occurred in 4–5 h

from the reception of the sample in the laboratory.

The experience gained and work accomplished enabled a quick

and effective laboratory response and permitted to increase train-

ing actions, BSL-3 facility upgrading, development of national
