An epidemic of acute haemorrhagic conjunctivitis in Belém, Pará, Brazil, was investigated. From 83 patients, 73 samples of virus was isolated in cultures of HEP-2 cells from conjunctival swab and throat swab. The virus isolates were identified in Centers for Disease Control, Atlanta, Georgia, USA, as an antigenic variant of coxsackievirus A24.(More)
During three years (1988-1990) blood samples from 307 people were taken to test antibodies for Human Immunodeficiency Virus type 1 (HIV-1) in homo and bisexual males living in Belém, being 149 (48.5%) of the former and 158 (51.5%) of the later. All patients requested examinations spontaneously to find out their status. The ages of tested people ranged from(More)
Seismo-volcano source localization is essential to improve our understanding of volcano systems. The lack of clear seismic wave phases prohibits the use of classical location methods. Seismic antennas composed of one-component (1C) seismometers provide a good estimate of the back-azimuth of the waveeld. The depth estimation, on the other hand, is difcult or(More)
Seismo-volcano source localization is essential to improve our understanding of eruptive dynamics and of magmatic systems. The lack of clear seismic wave phases prohibits the use of classical location methods. Seismic antennas composed of one-component (1C) seismometers provide a good estimate of the backazimuth of the wavefield. The depth estimation, on(More)
