Enveloped virus infectivity recovery after lyophilization.

<p>Chikungunya virus and Herpesvirus type 1 were freeze dried with/without different stabilizers using two different protocols (LP1 and LP2). After seven days at different temperature storage (-20°C, +4°C, +20°C), infectivity of each virus formulation were determinate by TCID₅₀ assays. Chikungunya virus infectivity after storage at -20°C, +4°C, +20°C. Herpesvirus type 1 infectivity after storage at -20°C, +4°C, +20°C.* TCID50/ml >10⁸.</p

Non enveloped virus infectivity recovery after lyophilization.

<p>Human Echovirus 13 and Human Adenovirus type C were freeze dried with/without different stabilizers using two different protocols (LP1 and LP2). After seven days at different temperature storage (-20°C, +4°C, +20°C), infectivity of each virus formulation were determinate by TCID₅₀ assays. Human Echovirus 13 infectivity after storage at -20°C, +4°C, +20°C. Human Adenovirus type C infectivity after storage at -20°C, +4°C, +20°C.</p

Zika virus seroprevalence in Bolivian volunteer blood donors.

<p>Samples were collected in December 2016 (Beni) and from March to April 2017 (other regions). The figure shows in each of the five regions investigated the proportion of samples positives in both ELISA and Virus Neutralisation Test (the black circle represents the proportion of positives): Santa Cruz (altitude ~400m) and Beni (alt. ~150m) have tropical climate; Cochabamba (alt. ~2500m), Tarija (alt. ~1850m), and especially La Paz (alt. ~3650m) have colder subtropical highland climates.</p
